LAIR1 Leukocyte-associated immunoglobulin-like receptor 1 is a protein that in humans is encoded by the ''LAIR1'' gene. LAIR1 has also been designated as CD305 (cluster of differentiation 305). Function The protein encoded by this gene is an inhibit ...

, an inhibitory receptor present on mononuclear leukocytes. This gene maps to a region of 19q13.4, termed the leukocyte receptor cluster, which contains 29 genes in the immunoglobulin superfamily, including LAIR1. The function of this protein is unknown, although it is thought to be secreted and may help modulate mucosal tolerance. Two

transcript variant Alternative splicing, or alternative RNA splicing, or differential splicing, is an alternative splicing process during gene expression that allows a single gene to code for multiple proteins. In this process, particular exons of a gene may be in ...
