CD300A

CD300A (CD300a Molecule) is a Protein Coding gene. Diseases associated with CD300A include Kabuki Syndrome 1. Among its related pathways are Innate Immune System and Class I MHC mediated antigen processing and presentation. Gene Ontology (GO) annotations related to this gene include phosphatidylserine binding and signaling receptor activity. An important paralog of this gene is CD300C.

CD300a Molecule

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 (PubMed:10746781, PubMed:16339535, PubMed:9701027).
Negatively regulates the Toll-like receptor (TLR) signaling mediated by MYD88 but not TRIF through activation of PTPN6 (PubMed:22043923).
