Description
HCST (Hematopoietic Cell Signal Transducer, also known as DAP1) is a Protein Coding gene. HCST belongs to the DAP10 family. It is a transmembrane signaling adaptor that contains a YxxM motif in its cytoplasmic domain. The encoded protein may form part of the immune recognition receptor complex with the C-type lectin-like receptor NKG2D. HCST may be part of the immune recognition receptor complex. This receptor plays a major role in triggering cytotoxicity against target cells expressing cell surface ligands such as MHC class I chain-related MICA and MICB, and UL16-binding proteins (ULBPs). It may activate phosphatidylinositol 3-kinase dependent signaling pathways through its intracytoplasmic YxxM motif
