Human ITPRIPL1 Protein, His Tag

Inositol 1, 4, 5-triphosphate receptor interacting protein like 1 (ITPRIPL1) is a single transmembrane protein, exhibits normal testis-enriched expression and widespread overexpression in various human cancers. ITPRIPL1 is commonly found in tumors with low PD-L1 expression. ITPRIPL1 acts as a natural ligand for CD3 ε, evading immune surveillance, leading to decreased T cell activity and promoting tumor growth. Research has shown that inducing stable CD3E-NCK1 binding prevents CD3E-ZAP70 interaction, subsequently inhibiting downstream ERK-NFkB signaling cascade and calcium influx activation.

ITPRIPL1

This protein carries a polyhistidine tag at the C-terminus. The protein has a calculated MW of 11.2 kDa. The protein migrates as 11 kDa and 13 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
