AffiAB® Anti-Hu CD335 PE [9E2]

Overview

CD335 is a type I transmembrane glycoprotein, which serves as one of natural cytotoxicity receptors, and represents major receptor informing NK cells that they should kill particular virus-infected or tumor cell. Its sialic acids residues are involved in recognition of viral hemagglutinins, similarly it recognizes heparan sulphate proteoglycans on the surface of tumor cells. CD335 transfers the signal downstream via association with CD3 zeta chain, that contains intracellular ITAM motifs. Expression of CD335, a specific marker of NK cells (both resting and activated), is down regulated by cortisol, and up-regulated by prolactin.
