General annotation (Comments)

Function

One of the major glycoproteins of thymocytes and T lymphocytes. Plays a role in the physicochemical properties of the T-cell surface and in lectin binding. Presents carbohydrate ligands to selectins. Has an extended rodlike structure that could protrude above the glycocalyx of the cell and allow multiple glycan chains to be accessible for binding. Is a counter-receptor for SN/Siglec-1. During T-cell activation is actively removed from the T-cell-APC (antigen-presenting cell) contact site thus suggesting a negative regulatory role in adaptive immune response. Ref.7

Subunit structure

Interacts with HIPK2 via the cytoplasmic domain. Interacts with RDX. Ref.5 Ref.6

Subcellular location

Membrane; Single-pass type I membrane protein.

Tissue specificity

Cell surface of thymocytes, T-lymphocytes, neutrophils, plasma cells and myelomas.

Post-translational modification

Has a high content of sialic acid and O-linked carbohydrate structures.
