Anti-Human TRGV9/Vγ 9(TCR) Polyclonal Antibody (HP264014)

Please refer to the specific buffer information in the hardcopy of datasheet or the lot-specific COA.

T cell receptor gamma variable 9 (TRGV9/Vγ 9) is a ~13 kDa protein. V region of the variable domain of T cell receptor (TR) gamma chain that participates in the antigen recognition. Gamma-delta TRs recognize a variety of self and foreign non-peptide antigens frequently expressed at the epithelial boundaries between the host and external environment, including endogenous lipids presented by MH-like protein CD1D and phosphoantigens presented by butyrophilin-like molecule BTN3A1. Upon antigen recognition induces rapid, innate-like immune responses involved in pathogen clearance and tissue repair. Binding of gamma-delta TR complex to antigen triggers phosphorylation of immunoreceptor tyrosine-based activation motifs (ITAMs) in the CD3 chains by the LCK and FYN kinases, allowing the recruitment, phosphorylation, and activation of ZAP70 that facilitates phosphorylation of the scaffolding proteins LCP2 and LAT. This lead to the formation of a supramolecular signalosome that recruits the phospholipase PLCG1, resulting in calcium mobilization and ERK activation, ultimately leading to T cell expansion and differentiation into effector cells.
