Optineurin (OPTN) is an autophagy receptor that interacts with numerous proteins. It is involved in regulating many cellular functions, including vesicular trafficking from the Golgi to plasma membrane, endocytic trafficking, and signaling leading to NF-kappa-B (see 164011) activation [1]
Optineurin has been shown to interact with huntingtin [2], transcription factor IIIA [3], and RAB8 [4] and may therefore function in cellular morphogenesis and membrane trafficking, vesicle trafficking, and transcription activation. Alternative splicing of the gene results in multiple transcript variants encoding the same protein.
Optineurin mutations are associated with Glaucoma and Amyotrophic lateral sclerosis (ALS).

Protein standard buffer composition: Protein standard buffer composition: Glycerol 10%, Tris Base 141 mM, Tris HCl 106 mM, LDS 2%, EDTA 0.51 mM, SERVA® Blue G250 0.22 mM, Phenol Red 0.175 mM, pH 8.5, 0.1mg/ml PefaBloc protease inhibitor (Roche), 50mM DTT.
Application Details:
Positive control: a 2 μL load per well is optimal for most chemiluminescent detection systems. Standard curve: 3 loads are recommended (eg. 0.5, 2 and 4μL). For most applications a sample load of 0.2 μg of chlorophyll will give a PsaC signal in this range. Exact loads can vary with the sensitivity of your system and the abundance of the target protein in your samples. Note: Optimal quantitation is achieved using moderate sample loads/well, generally 1 to 5 ug total protein. A trial experiment may be required i) to bring your sample load within the standard curve range and ii) to obtain a signal that is strong enough to reliably quantify but not so strong as to consume ECL reagents too quickly or saturate your detection system. These goals may achieved by adjusting both sample and standard loads.
Reconstitution:
For reconstitution add 95 µl of sterile water. Note that due to glycerol in buffer, the lyophilized product appears as a dense liquid rather than a powder. Allow the product several minutes to solubilize after adding water. Mix thoroughly but gently. Avoid vigorous vortexing, as buffer contains detergent. Upon reconstitution, this standard is ready-to-load and does not require any additions or heating. See additional Handling Instructions below. PsaC standard protein concentration: 0.10 pmol/µl.

Handling Instructions*IMPORTANT: In our experience, viscous liquids are surprisingly stable; insufficient mixing is the most common reason for unsatisfactory results. Following mixing, briefly pulse in a microcentrifuge to collect material from cap.Standard needs to be fully thawed and thoroughly mixed before each use. Proteins tend to stratify with the more dense layer after freezing. We recommend bringing the product to room temperature and either mixing by inverting or flicking tube 5-10 times. Pipetting up and down may also provide sufficient mixing, provided the tip is moved within the tube while taking up and expelling the liquid.

The RbcL (Rubisco large subunit) protein is hyperabundant and regulation of RbcL content under different conditions or stress responses sets a limit on the maximum capacity for CO2 uptake in a population or community.Proteins involved in conversion of solar energy into chemical bonds:PsaC protein of multisubunit protein complex - Photosystem I, which harnesses light energy required for photosynthesis to occur.PsbA protein of multisubunit complex - Photosystem II - the ultimate source of almost all biosynthetic reductant in the biosphere. PsbA (D1) protein is rapidly cycled under illumination in all oxygenic photobionts. Tracking PsbA pools using the Global PsbA Antibody shows the functional content of Photosystem II in a wide range of samples.Lhcb1 - harnesses light energy for photosynthesis (Photosystem II)AtpB highly conserved across the beta subunits of known F-type ATP Synthases from chloroplasts, mitochondria and most bacteria. The ATP Synthase complex is essential for the synthesis of ATP from ADP and free phosphate

Suggested experimental treatments for student labs: - Low light vs. High lightShift from low or moderate light (50-100 umol photons m-2 s-1) to high light (500-2000 umol photons m-2 s-1, or nearly full sunlight). Note: Depending on the species and the developmental stage this will lead to large changes in protein profiles, usually within a few hours and is reflected in detectable differences in LHC & RbcL content, and also differences in the PsbA/PsaC ratio (PSII:PSI).-PsbA breakdown products will become more prominent, and the pool of mature PsbA usually declines -there may be declines in antenna proteins, and sometimes increases in RbcL, if the stress is not too harsh. For higher crop plants, it is probably the most generally reliable, rapid way to provoke detectable changes in protein content, since the PsbA/D1 pool will usually decline. - Changes in nutritional statusShifting from nutrient replete to low-nutrient conditions will cause gradual declines in LHC & RbcL content. Etiolation vs. greening Characteristic change, usually PSI (PsaC) accumulates before PSII (PsbA) and LHCII can be observed. Developmental stagesNewly emerged, young & old leaves will show different profiles, as will (of course) leaves & roots.Suggested material: Plants (spinach, sunflower, pea), Algae or cyanobacteria.Material preparation and extraction: Tissue samples of the size required for later extraction can be frozen in foil sachets and stored at â80ºC. Extraction buffer: LiDS is recommended over SDS for extraction involving cold steps. Protease inhibitor: PEFABLOC. For a teaching lab, this may not be strictly necessary, however if extracts are to be refrozen and reused, degradation becomes an issue and addition of protease inhibitor is advised.Recommended extraction volume: 150 mg of leaf tissue into 500 ul of extraction buffer (see appendix). After the extraction by grinding and/or sonication the mixture is centrifuged (full speed in microfuge for 2 min) to separate solubilized extract from bulk leaf material. The recovery of extract should be about 300 ul, depending on the type of leaves. This gives an extract at a concentration of roughly 100 ug chl/ml (0.1 ug chl/ul). Load per well: ca. 0.5 ug chl (so ca. 5 ul of the extract). So 150 mg of leaf tissue should give a recovered extract of 300 ul @ 0.1 ug chl/ul = 30 ug chl, sufficient for about 60 lane loads of 0.5 ug chl/lane for immunoblotting The loads can be reduced easily down to 0.2 ug chl (for mini gels) or even lower (down to 0.01 ug chl in some cases using ultrasensitive detection methods). Lighter loads are recommended for some abundant proteins detected with strong antibodies (like anti-RbcL). Alternatively, for ease of extraction it can be scaled up to 1 g of tissue in 4 ml of extraction buffer. Loads can be prepared based on: chlorophyll, protein or leaf area.Chlorophyll is suitable and simple loading parameter for determination of the level of the photosynthetic apparatus, which accounts for most leaf protein. Therefore loading by equal chlorophyll can show both qualitative and quantitative changes in a protein profile. For leaves, loads by equal area are recommended, as a leaf is nearly 2-dimensional and photosynthetic capacity per leaf area is a useful ecophysiological parameter.Spectrophotometric chl determinationExtract chl from ca. 100 ul of aqueous extract into 900 ul of 80% acetone saturated with MgCO3. Measure at A663 and A750 (Blank=1 ml 80 % acetone). [Chla](μg.ml-1) = 12.7 (A663-A750)x 1000/xQuantitationIt is recommended to run 3 lanes of quantitated standard to generate a standard curve. It can be helpful to perform trial runs to get the quantitation standards and samples in the same range. Immunoblottting with primary and secondary antibodies and ECL shows linearity of detection over about 1 order of magnitude. Bands are detected over a much wider range, but the pseudo-linearity load/response region is only about 10 fold.Agrisera Western blot protocols and additional information about antibodies

Phosphoenolpyruvate carboxylase (PEPC; EC 4.1.1.31) serves as an important control element in the regulation of photosynthetic carbon metabolism in C4 and CAM plants. This is the first enzyme of the pathway, and PEPC enzymes are encoded by a small multigenic family. Several isoforms of PEPC have been characterised in maize, sorghum and sugarcane. These isoforms are involved in several functions such as the initial fixation of atmospheric CO2 (= C4 PEPC) and anaplerotic functions associated with nitrogen assimilation or amino acid biosynthesis (Lepiniec et al. 1994).

Concentration: after re-constitution with sterile milliQ water final concentration of the standard is 0.15 pmoles/µlProtein standard buffer composition: Glycerol 10%, Tris Base 141 mM, Tris HCl 106 mM, LDS 2%, EDTA 0.51 mM, SERVA® Blue G250 0.22 mM, Phenol Red 0.175 mM, pH 8.5, 0.1mg/ml PefaBloc protease inhibitor (Roche), 50 mM DTT.This standard is ready-to-load and does not require any additions or heating. It needs to be fully thawed and thoroughly mixed prior to using. Avoid vigorous vortexing, as buffers contain detergent. Following mixing, briefly pulse in a microcentrifuge to collect material from cap.This standard is stabilized and ready and does not require heating before loading on the gel. Please note that this product contains 10% glycerol and might appear as liquid but is provided lyophilized. Allow the product several minutes to solubilize after adding water. Mix thoroughly but gently Take extra care to mix thoroughly before each use, as the proteins tend to settle with the more dense layer after freezing.
Application Details:
Standard curve: 3 loads are recommended (0.5, 2 and 4μl).For most applications a sample load of 0.2 μg of chlorophyll/well will give a RbcL signal in this range.Positive control: a 2 μl load per well is optimal for most chemiluminescent detection systems. Higher standard concentration needs to be used to allow detection by Coomasie stains. Such gels with higher standard concentration can not be used for quantitation using chemiluminescence.This standard is stabilized and ready and does not require heating before loading on the gel.Please note that this product contains 10% glycerol and might appear as liquid but is provided lyophilized. Allow the product several minutes to solubilize after adding water.
