Background:
Plexins are a family of large integral membrane proteins that complex with neuropilins to form semaphorin co-receptors. The extracellular region of plexins contains a semaphorin domain, multiple glycine-rich motifs, and MET-related sequences. The cytoplasmic region contains a Sex/Plexin domain and putative tyrosine phosphorylation sites that mediate signal transduction after activation. Plexin D1 is a type I transmembrane protein that may be expressed as multiple isoforms in many cell types, including neurons and endothelial cells. Semaphorin 3E (Sema-3E) and semaphorin 4A can bind Plexin D1, and ligand binding leads to phosphorylation of Tyr-1642 and activation of Plexin D1. Sema-3E and its receptor are important for angiogenesis that occurs during blood vessel development and repair. In cancers, Sema-3E and Plexin D1 are expressed in tumor tissues and cancer cells, and the interaction of these molecules may promote cancer cell migration and metastic spreading. Thus, Plexin D1, and its ligand Sema-3E, may be important regulators of angiogenesis and metastasis.
Sequence: Plexin D1 synthetic peptide corresponds to amino acids in the cytoplasmic domain from human Plexin D1. This sequence is well conserved in rat and mouse Plexin D1, and has low homology to other Plexin family members.
Specificity: The peptide is specifically recognized by anti-Plexin D1 (Cytoplasmic domain) antibody (PP4401) in ELISA, and has been shown to block the reactivity of PP4401 during Western blot. In addition, the peptide is recommended for use in blocking PP4401 reactivity in immunocytochemistry.
Buffer/Storage:
Blocking Peptide is supplied in 50µl phosphate-buffered saline and 0.05% sodium azide. Store at –20°C. Stable for 1 year.
