Havcr1
Function
Phosphatidylserine receptor that plays an important functional role in regulatory B-cells homeostasis including generation, expansion and suppressor functions (By similarity). As P-selectin/SELPLG ligand, plays a specialized role in activated but not naive T-cell trafficking during inflammatory responses. Controls thereby T-cell accumulation in the inflamed central nervous system (CNS) and the induction of autoimmune disease (By similarity). Regulates also expression of various anti-inflammatory cytokines and co-inhibitory ligands including IL10. Acts as a regulator of T-cell proliferation (By similarity). May play a role in kidney injury and repair (By similarity).
Sequence Similarities
Belongs to the immunoglobulin superfamily. TIM family.
Tissue Specificity
Expressed at a low level in normal kidney but are increased dramatically in postischemic kidney. Expressed in proliferating bromodeoxyuridine-positive and dedifferentiated vimentin-positive epithelial cells in regenerating proximal tubules.
Cellular localization
- Cell membrane
- Single-pass type I membrane protein
