Description
CD300 antigen-like family member A (CD300A) is also known as CMRF35-like molecule 8 (CLM-8), CMRF-35-H9, CMRF35-H, Immunoglobulin superfamily member 12 (IGSF12), NK inhibitory receptor, LMIR1, which belongs to the CD300 family. CD300A contains one Ig-like V-type (immunoglobulin-like) domain. CD300A is expressed not only by natural killer (NK) cells but also by T-cell subsets, B-cells, dendritic cells, mast cells, granulocytes and monocytes. CD300A is a inhibitory receptor which may contribute to the down-regulation of cytolytic activity in natural killer (NK) cells, and to the down-regulation of mast cell degranulation
