Supplementary information

The 'LILRB3' protein also known as Leukocyte Immunoglobulin Like Receptor B3 is an inhibitory receptor that plays a role in immune response regulation. It weighs approximately 60 kDa and expresses mainly on myeloid cells such as monocytes macrophages and dendritic cells. The receptor interacts with MHC class I molecules and helps in maintaining immune system balance by transmitting inhibitory signals to the immune cells.
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.

Malfunction or dysregulation of LILRB3 can lead to autoimmune diseases and affect inflammation levels. It is associated with diseases such as rheumatoid arthritis and systemic lupus erythematosus where immune regulation becomes compromised. The interaction of LILRB3 with proteins like human leukocyte antigen (HLA) systems implies a role in autoimmunity making it a target of interest for therapeutic strategies aiming to restore immune balance.

Product protocols

Target data

May act as receptor for class I MHC antigens. Becomes activated upon coligation of LILRB3 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).
