Description: This Human Paxillin (PXN) ELISA Kit employs a two-site sandwich ELISA to quantitate PXN in samples. An antibody specific for PXN has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any PXN present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for PXN is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of PXN bound in the initial step. The color development is stopped and the intensity of the color is measured.

Background: Paxillin is a signal transduction adaptor protein and should not be confused with the neurotoxin paxilline.Glenney and Zokas (1989) used an antiphosphotyrosine antibody to identify proteins that are phosphorylated in Rous sarcoma virus-transformed chick embryo fibroblasts, and found a 76-kD protein that localizes to focal adhesions at the ends of actin-containing stress fibers in nontransformed cells. Turner et al. (1990) purified this protein from chicken gizzard smooth muscle, and named it paxillin ('paxillus' means 'small stake' or 'peg' in Latin) as a protein tethered to the membrane at focal adhesions.Paxillin migrates as a diffuse 65- to 70-kD band on SDS-PAGE. Salgia et al. (1995) stated that transmembrane integrin molecules connect the actin cytoskeleton to the extracellular matrix within focal adhesions.

NCBI Description

This gene encodes a cytoskeletal protein involved in actin-membrane attachment at sites of cell adhesion to the extracellular matrix (focal adhesion). Alternatively spliced transcript variants encoding different isoforms have been described for this gene. These isoforms exhibit different expression pattern, and have different biochemical, as well as physiological properties (PMID:9054445). [provided by RefSeq, Aug 2011]

Uniprot Description

PXN: a multi-domain cytoskeletal protein involved in actin-membrane attachment that localizes primarily to focal adhesion sites to the extracellular matrix. Phosphorylated by focal adhesion kinase (FAK) and is a component of integrin signaling. Its phosphorylation provides docking sites for recruitment of signaling molecules to focal adhesions. Binds in vitro to vinculin as well as to the SH3 domain of c-SRC and, when tyrosine phosphorylated, to the Crk SH2 domain. Interacts with GIT1, NUDT16L1/SDOS, PARVA and TGFB1I1. Component of cytoplasmic complexes, which also contain GIT1, ARHGEF6 and PAK1. Binds DDEF2. Interacts with unphosphorylated ITGA4. Interacts with RNF5.Three alternatively-spliced isoforms have been described. Isoform beta binds to focal adhesion kinase but weakly to vinculin. Isoform gamma binds to vinculin but only weakly to focal adhesion kinase.
