Gene(ID):
Expression:
P30203 CD6_HUMAN:

Detected on thymocytes (PubMed:15294938). Detected on peripheral blood T-cells (PubMed:15048703, PubMed:16352806). Detected on natural killer (NK) cells (PubMed:16352806). Soluble CD6 is detected in blood serum (at protein level) (PubMed:17601777). Detected in spleen, thymus, appendix, lymph node and peripheral blood leukocytes (PubMed:9013954). Expressed by thymocytes, mature T-cells, a subset of B-cells known as B-1 cells, and by some cells in the brain.

Description:
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.

Research Backgrounds

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 costimulatory molecule; promotes T-cell activation and proliferation. Contributes to the formation and maturation of the immunological synapse. Functions as 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. LPS binding leads to the activation of signaling cascades and down-stream MAP kinases. Mediates activation of the inflammatory response and the secretion of pro-inflammatory cytokines in response to LPS.

PTMs:

After T-cell activation, becomes hyperphosphorylated on Ser and Thr residues and phosphorylated on Tyr residues.

Glycosylated.

Subcellular Location:

Cell membrane>Single-pass type I membrane protein.
Note: Detected at the immunological synapse, i.e, at the contact zone between antigen-presenting dendritic cells and T-cells (PubMed:15294938, PubMed:16352806). Colocalizes with the TCR/CD3 complex at the immunological synapse (PubMed:15294938).

Secreted.
Note: The origins of the secreted form are not clear, but it might be created by proteolytic shedding of the ectodomain.

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.

Subunit Structure:

Interacts (via extracellular domain) with ALCAM/CD166 (via extracellular domain). Interacts with the TCR/CD3 complex subunit CD3E. Interacts (via tyrosine phosphorylated C-terminus) with LCP2 (via SH2 domain). Interacts with VAV1 (By similarity). Interacts (via glycosylated extracellular domain) with LGALS1 and LGALS3. Interaction with LGALS1 or LGALS3 inhibits interaction with ALCAM.
