This gene may be associated with susceptibility to multiple sclerosis. The encoded CD6 protein contains three scavenger receptor cysteine-rich (SRCR) domains and a binding site for an activated leukocyte cell adhesion molecule. Studies have shown CD6 regulates T-cell responses through activation-dependent recruitment of the positive regulator SLP-76. CD6 expression is found on the outer membrane of T-lymphocytes and important for continuation of T cell activation"}]}]}
