DomainThe CD6 binding site is located in the N-terminal Ig-like domain. {ECO:0000269|PubMed:8823162}.
FunctionCell adhesion molecule that binds to CD6. Involved in neurite extension by neurons via heterophilic and homophilic interactions. May play a role in the binding of T- and B-cells to activated leukocytes, as well as in interactions between cells of the nervous system.

SimilarityContains 2 Ig-like V-type (immunoglobulin-like) domains. {ECO:0000305}.
SimilarityContains 3 Ig-like C2-type (immunoglobulin-like) domains. {ECO:0000305}.
Subcellular LocationIsoform 3: Secreted {ECO:0000269|PubMed:15496415}.
Subcellular LocationMembrane; Single-pass type I membrane protein.
Tissue SpecificitySpleen, placenta, liver, and weakly in liver. Expressed by activated T-cells, B-cells, monocytes and thymic epithelial cells. Expressed by neurons in the brain. Restricted expression in tumor cell lines. Preferentially expressed in highly metastasizing melanoma cell lines. {ECO:0000269|PubMed:9502422}.
