CD6 Antibody – Rabbit Polyclonal

This gene encodes a protein found on the outer membrane of T-lymphocytes as well as some other immune cells. The encoded protein contains three scavenger receptor cysteine-rich (SRCR) domains and a binding site for an activated leukocyte cell adhesion molecule. The gene product is important for continuation of T cell activation. This gene may be associated with susceptibility to multiple sclerosis (PMID: 19525953, 21849685). Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2011]

CD6: a type I membrane protein involved in cell adhesion. Binds to CD166. Expressed on thymocytes, peripheral T cells, a subset of B cells, and a subset of neurons. Mediates the binding of developing thymocytes with thymic epithelial cells. CD6- T cells are less autoreactive than CD6+ T cells. Phosphorylated on tyrosines and serines following T cell antigen receptor signaling. Five splice-variant isoforms have been described.
