Biological function summary
The LILRB3 protein participates in downregulating immune cell activation and preventing overactivation that might lead to tissue damage. It belongs to the family of leukocyte immunoglobulin-like receptors. LILRB3 cooperates with other molecules on the cell surface to form a complex that modulates immune response via the transmission of inhibitory signals.
Pathways
The LILRB3 protein is involved in the immune checkpoint pathways that regulate immune cell activity and tolerance. It has important connections with the NF-κB pathway influencing the inflammatory response and maturation of dendritic cells. LILRB3's function relates to the PD-1 pathway which is another regulatory mechanism that ensures immune cells do not become overly active.
일반 정보
기능
May act as receptor for class I MHC antigens. Becomes activated upon coligation of PIRB and immune receptors, such as FCGR2B and the B-cell receptor. Down-regulates antigen-induced B-cell activation by recruiting phosphatases to its immunoreceptor tyrosine-based inhibitor motifs (ITIM).
Post-translational modifications
Phosphorylated on tyrosine residues by LYN. Phosphorylation at Tyr-794 and Tyr-824 by LYN is important for interaction with PTPN6/SHP-1 and PTPN11/SHP-2.
