Rabbit anti-Human MICA Polyclonal Antibody

Uniprot Id

Q29983

Target Species

Human

Target Name

MICA

Target Full Name

MHC class I polypeptide-related sequence A

Target Function

Seems to have no role in antigen presentation. Acts as a stress-induced self-antigen that is recognized by gamma delta T-cells. Ligand for the KLRK1/NKG2D receptor. Binding to KLRK1 leads to cell lysis.

Target Involvement

Psoriasis 1 (PSORS1); Psoriatic arthritis (PSORAS)

Target Subcellular Location

Cell membrane; Single-pass type I membrane protein. Cytoplasm.

Target Protein Families

MHC class I family, MIC subfamily

Target Tissue Specificity

Widely expressed with the exception of the central nervous system where it is absent. Expressed predominantly in gastric epithelium and also in monocytes, keratinocytes, endothelial cells, fibroblasts and in the outer layer of Hassal's corpuscles within t

Target Synonyms

MHC class I chain-related protein A; MHC class I chain-related protein B; MHC class I polypeptide related sequence A; MHC class I polypeptide related sequence B; MHC class I polypeptide-related sequence A; MIC-A; micA; MICA_HUMAN; MICB

Target Background

This gene encodes the highly polymorphic major histocompatability complex class I chain-related protein A. The protein product is expressed on the cell surface, although unlike canonical class I molecules it does not seem to associate with beta-2-microglobulin. It is a ligand for the NKG2-D type II integral membrane protein receptor. The protein functions as a stress-induced antigen that is broadly recognized by intestinal epithelial gamma delta T cells. Variations in this gene have been associated with susceptibility to psoriasis 1 and psoriatic arthritis, and the shedding of MICA-related antibodies and ligands is involved in the progression from monoclonal gammopathy of undetermined significance to multiple myeloma. Alternative splicing of this gene results in multiple transcript variants.
