Activity summary

LAIR1 also known as Leukocyte-Associated Immunoglobulin-like Receptor 1 is a transmembrane protein with a molecular weight of approximately 32 kDa. It expresses mainly on immune cells including T cells B cells and myeloid cells. This receptor by binding to collagen plays a significant role in controlling immune cell signaling. It acts as an inhibitory receptor which helps in maintaining immune system balance and prevents excessive immune responses.

Biological function summary

LAIR1 functions by modulating immune responses and maintaining homeostasis in the immune system. It is a part of a complex pathway involved in inhibitory signaling. When LAIR1 binds to its ligand such as collagen it transduces a signal that reduces activation of immune cells. This inhibition ensures that immune cells do not become overactive which could otherwise lead to tissue damage.

Pathways

LAIR1 participates in immune checkpoint regulation and collagen interaction pathways. It interacts with proteins such as ITIM-containing molecules which transmit inhibitory signals essential for regulating immune cell activation. It also indirectly connects to the TGF-beta signaling pathway which is vital for controlling cell differentiation and immune regulation.

Associated diseases and disorders

LAIR1 is of interest due to its connection to autoimmune diseases and certain cancers. In autoimmune diseases such as rheumatoid arthritis dysregulated LAIR1 signaling may contribute to inflammation. The protein is also linked to cancer where its inhibitory signaling might affect tumor immune evasion. The connection between LAIR1 and these conditions involves proteins like autoimmune-related genes and tumor-associated surface molecules.
