Specificity
Clone 4B20 is a ZooMAb rabbit recombinant monoclonal antibody that specifically detects GRB2-associated-binding protein 1 (Gab1). It targets an epitope within 30 amino acids from the C-terminal region.
KLH-conjugated Linear Peptide corresponding to 30 amino acids from the C-terminal region of Human Gab1.
Western Blotting Analysis: A 1:1,000 dilution from a representative lot detected Gab1 in fetal bovine heart endothelial (FBHE) cell lysate.
Immunohistochemistry (Paraffin) Analysis: A 1:100 dilution from a representative lot detected Gab1 in human small intestine tissue sections.
Affinity Binding Assay: A representative lot of this antibody bound Gab1 peptide with a KD of 4.0 x 10-6 in affinity binding assay.
Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user.
Anti-Gab1, clone 4B20 ZooMAb, Cat. No. ZRB1348, is a recombinant Rabbit monoclonal antibody that specifically targets GRB2-associated-binding protein 1 (Gab1) and has been tested for use in Affinity Binding Assay, Immunohistochemistry (Paraffin), and Western Blotting.
Target description
GRB2-associated-binding protein 1 (UniProt: Q13480; also known as GRB2-associated binder 1, Growth factor receptor bound protein 2-associated protein 1; Gab1) is encoded by the GAB1 gene (Gene ID: 2549) in human. Gab1 is a scaffolding protein that plays a role in intracellular signaling cascades triggered by activated receptor-type kinases. It recruits PI-3 kinase and other effector proteins in response to the activation of many receptor tyrosine kinases (RTKs). Gab1 can be phosphorylated on at least 16 sites by multiple receptor tyrosine kinase (RTKs), including: insulin receptor (IR), platelet derived growth factor receptor beta, hepatocyte growth factor/scatter factor receptor, and epidermal growth factor receptor. Phosphorylation of Gab1 on tyrosine 627 and tyrosine 659 is shown to be critical for its binding to SHP2, and for activation of the ERK/MAPK pathway in response to EGF. Tyrosine phosphorylation of Gab1 mediates interaction with several proteins that contain SH2 domains. Gab1 plays important roles in embryonic development and cell migration and is shown to be a critical component in the interaction between focal adhesion kinase and Met in cancer cell invasion. Gab1 is also reported to be a major target in linoleic acid (LA)-induced enhancement of tumorigenesis. Mutations in GAB1 gene are known to cause autosomal recessive deafness that is characterized by severe to profound hearing loss resulting from damage to the neural receptors of the inner ear or the nerve pathways to the brain. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
