CC -!- FUNCTION: Cell adhesion molecule that mediates both heterotypic cell-
CC cell contacts via its interaction with CD6, as well as homotypic cell-
CC cell contacts. Promotes T-cell activation and proliferation via its
CC interactions with CD6 (By similarity). Contributes to the formation and
CC maturation of the immunological synapse via its interactions with CD6
CC (By similarity). Mediates homotypic interactions with cells that
CC express ALCAM. Mediates attachment of dendritic cells onto endothelial
CC cells via homotypic interaction. Inhibits endothelial cell migration
CC and promotes endothelial tube formation via homotypic interactions.
CC Required for normal organization of the lymph vessel network. Required
CC for normal hematopoietic stem cell engraftment in the bone marrow.
CC Plays a role in hematopoiesis; required for normal numbers of
CC hematopoietic stem cells in bone marrow. Promotes in vitro osteoblast
CC proliferation and differentiation (By similarity). Promotes neurite
CC extension, axon growth and axon guidance; axons grow preferentially on
CC surfaces that contain ALCAM (By similarity). Mediates outgrowth and
CC pathfinding for retinal ganglion cell axons (By similarity).
CC {ECO:0000250|UniProtKB:P42292, ECO:0000250|UniProtKB:Q13740,
CC ECO:0000250|UniProtKB:Q61490}.
CC -!- SUBUNIT: Homodimer. Interacts (via extracellular domain) with CD6 (via
CC extracellular domain). Homodimerization and interaction with CD6
CC involve the same region and cannot occur simultaneously. The affinity
CC for CD6 is much higher than the affinity for self-association.
CC Interacts (via glycosylated extracellular domain) with LGALS1 and
CC LGALS3. Interaction with LGALS1 or LGALS3 inhibits interaction with
CC CD6. {ECO:0000250|UniProtKB:Q13740}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:Q61490};
CC Single-pass type I membrane protein {ECO:0000250|UniProtKB:Q61490}.
CC Cell projection, axon {ECO:0000250|UniProtKB:Q61490}. Cell projection,
CC dendrite {ECO:0000250|UniProtKB:Q61490}. Note=Detected at the
CC immunological synapse, i.e, at the contact zone between antigen-
CC presenting dendritic cells and T-cells. Colocalizes with CD6 and the
CC TCR/CD3 complex at the immunological synapse.
CC {ECO:0000250|UniProtKB:Q13740}.
CC -!- DOMAIN: The CD6 binding site is located in the N-terminal Ig-like
CC domain. {ECO:0000250|UniProtKB:Q13740}.
CC -!- PTM: Glycosylated. {ECO:0000250|UniProtKB:Q13740}.
