Function

Cell adhesion molecule that mediates cell-cell contacts and regulates T-cell responses via its interaction with ALCAM/CD166. Contributes to signaling cascades triggered by activation of the TCR/CD3 complex. Functions as a costimulatory molecule; promotes T-cell activation and proliferation.

Biological Context

Subcellular Location: Secreted
Tissue Specificity: Detected on thymocytes. Detected on peripheral blood T-cells. Detected on natural killer (NK) cells. Soluble CD6 is detected in blood serum (at protein level). Detected in spleen, thymus, appendix, lymph node and peripheral blood leukocytes. Expressed by thymocytes, mature T-cells, a subset of B-cells known as B-1 cells, and by some cells in the brain

Function

Cell adhesion molecule that mediates cell-cell contacts and regulates T-cell responses via its interaction with ALCAM/CD166 (PubMed:15048703, PubMed:15294938, PubMed:16352806, PubMed:16914752, PubMed:24584089, PubMed:24945728). Contributes to signaling cascades triggered by activation of the TCR/CD3 complex (PubMed:24584089). Functions as a costimulatory molecule; promotes T-cell activation and proliferation (PubMed:15294938, PubMed:16352806, PubMed:16914752). Contributes to the formation and maturation of the immunological synapse (PubMed:15294938, PubMed:16352806). Functions as a calcium-dependent pattern receptor that binds and aggregates both Gram-positive and Gram-negative bacteria. Binds both lipopolysaccharide (LPS) from Gram-negative bacteria and lipoteichoic acid from Gram-positive bacteria (PubMed:17601777). LPS binding leads to the activation of signaling cascades and down-stream MAP kinases (PubMed:17601777). Mediates activation of the inflammatory response and the secretion of pro-inflammatory cytokines in response to LPS (PubMed:17601777)

Subunit

Interacts (via extracellular domain) with ALCAM/CD166 (via extracellular domain) (PubMed:15048703, PubMed:16352806, PubMed:16914752, PubMed:24945728, PubMed:26146185).
