Descrizione generale

Platelet endothelial cell adhesion molecule (UniProt P16284; also known as CD31, EndoCAM, GPIIA′, PECA1, PECAM-1) is encoded by the PECAM1 gene (Gene ID 5175) in human. PECAM-1 (CD31) is a 130 kDa cell adhesion molecule that is expressed at the junctions of all continuous endothelia, as well as most bone marrow-derived hematopoietic cells, including platelets, monocytes, granulocytes and some lymphocytes. The human PECAM1 and murine Pecam1 genes both produce multiple spliced isoforms with varying lengths in cytoplasmic domain, with the isoform Long being the major form expressed in human tissues and endothelial cells (ECs), and isoform delta 14-15 being the predominantly expressed murine form. PECAM-1 plays an import role in maintaining vascular integrity and function by mediating ECs interactions with pericytes and smooth muscle cells (SMCs). PECAM-1 is initially produced with a signal peptide (human a.a. 1-27, murine a.a. 1-17) sequence, the removal of which yields the mature protein with a large extracellular region (human a.a. 28-601, mouse a.a. 18-590) composed of six C2-type Ig-like domains, followed by a transmembrane seqment (human a.a. 602-620, mouse a.a. 591-609) and a cytoplasmic tail (human a.a. 621-738, mouse a.a. 610-727) that plays an essential role in PECAM-1-mediated cellular signaling.

Specificità

Clone 4A8.1 was raised against the cytoplasmic domain of PECAM-1 (CD31) isoform Long. Reactivity toward spliced isoforms Delta12, Delta13, Delta14, Delta14-15, and Delta15 with various cytomplasmic domain deletions is possible, but has not not been confirmed.

Descrizione del bersaglio

~130 kDa observed. Target band size appears larger than the calculated molecular weights of 79.58/77.52/77.25/77.46/76.30/78.42 kDa (mature isoform Long/Delta12/Delta13/Delta14/Delta14-15/Delta15) and 82.54/80.48/80.21/80.42/79.26/81.38 kDa (isoform Long/Delta12/Delta13/Delta14/Delta14-15/Delta15 pro-form) due to glycosylation. Uncharacterized bands may be observed in some lysate(s).
