The areas above are those we cover right now, but we will be adding new research areas over time. Need an antibody to a new protein... Why not get in early?

 

For each focus areas we continually review the latest publications with the aim of identifying new target proteins of interest to make antibodies to. We develop many new antibodies each year.

Tdp 43 3 cat aa17 100105

TDP43 Antibodies

 

TAR DNA-binding protein 43 (TDP43) binds DNA and RNA and has multiple functions in transcriptional repression, pre-mRNA splicing and translational regulation.

 

Characterisation of transcriptome-wide binding sites shows that thousands of RNAs are bound by TDP43 in neurons.

 

Hyperphosphorylated, fragmented and ubiquitinated forms of TDP-43 have been identified as core components of cytosolic inclusions in ALS (amyotrophic lateral sclerosis) and FTLD (frontotemporal lobar degeneration). As well as...  read more

 



New antibody for Alzheimer’s research: Learn how the enzyme CYP46A1 controls brain cholesterol levels

 

Brain cholesterol is an important membrane building component of glial cells, neurons and myelin sheaths. Unable to cross the blood-brain-barrier, cholesterol is synthesised in situ, transported between the various cells and eliminated via oxidative pathways to maintain appropriate levels.

 

Key to regulating brain cholesterol homeostasis the CNS-specific cytochrome P450 enzyme, cholesterol 24-hydroxylase (CYP46A1) is mostly expressed in the brain, converting excess cholesterol to membrane-permeable 24HC (oxysterol, 24S-hydroxycholesterol). This oxidised product diffuses through the blood-brain-barrier entering the systemic circulation to reach the liver where it is degraded to bile acids. Accumulation of cholest... read more and find out about our CYP46A1 antibodies.

 



RNA-binding Proteins and Stress granules in ALS-FTD

 

Cytoplasmic stress granules are membrane-less aggregates that form through liquid phase separation as a protective response to physiological or pathological conditions such as oxidative stress, hypoxia or virus infection. They are transient and usually disappear after the stress is removed.

 

Stress granules are mainly composed of messenger RNAs (mRNAs) stalled in translation initiation, translation initiation components such as eukaryotic initiation factor 4G (eIF4G), RNA-binding proteins (RBPs) and ribonucleoproteins. Formation of stress granules can be initiated by the Ras GTPase-activating protein-binding protein 1 (G3BP1), which is commonly used as a stress granule marker.

 

Mutations in genes that encode RNA binding proteins (RBPs) such as FUS/TLS, TDP-43, Ataxin 2, TAF15, EWSR1, hnRNPA1 and hnRNPA2, MATR3 and TIA-1 have recently been linked to ALS/FTD. Some of these RNA binding proteins... read more.

 



The role of retromer component VPS-35 in neurodegenerative diseases

 

Endosomes are important protein sorting stations contributing to cell homeostasis. Cargoes, originating from the plasma membrane or the biosynthesis pathways and entering the endosomal system, are either retained in endosomes for subsequent lysosomal degradation or exported from the endosomes for reuse or recycling. Deficiencies in the endosomal sorting system have been linked to neurodegenerative diseases such as Alzheimer’s and Parkinson’s.

 

Retromer is an evolutionarily conserved protein essential for the transport of transmembrane proteins from the endosomes back to the trans-Golgi network or to the plasma membrane via the recycling pathway. Retromer is a pentameric complex composed of a cargo-selective trimeric complex, with the major subunit being VPS-35 (vacuolar protein sorting 35)... read more and find out about our anti VPS35 antibodies.

 



Anti-RAMP Antibodies (1, 2 and 3)

 

Receptor Activity Modifying Proteins (RAMPs) transport calcitonin-receptor-like receptors (CRLR or CALCRL) to the cell surface. CRLR is a G protein-coupled receptor with seven transmembrane domains, which can function as either a calcitonin-gene-related peptide (CGRP) receptor or an adrenomedullin receptor, depending on which member of the RAMP family transports it to the cell surface. Wth RAMP1 it produces a CGRP receptor with RAMP2 it produces an adrenomedullin (AM) receptor (AM1) with RAMP3 it produces a dual CGRP/AM receptor (AM2).
