Generic protein structure example

Leukocyte-associated immunoglobulin-like receptor 1 is a protein that in humans is encoded by the LAIR1 gene.[1][2] LAIR1 has also been designated as CD305 (cluster of differentiation 305).

Function

The protein encoded by this gene is an inhibitory receptor found on peripheral mononuclear cells, including NK cells, T cells, and B cells.[3] Inhibitory receptors regulate the immune response to prevent lysis of cells recognized as self. The gene is a member of both the immunoglobulin superfamily and the leukocyte-associated inhibitory receptor family. The gene maps to a region of 19q13.4 called the leukocyte receptor cluster, which contains at least 29 genes encoding leukocyte-expressed receptors of the immunoglobulin superfamily.[2]

Interactions

LAIR1 has been shown to interact with PTPN11[1][4] and PTPN6.[1][4][5][6][7]
