MHC class I polypeptide-related sequence A (MICA)

Target (abbrv.) MICA
Target (full name) MHC class I polypeptide-related sequence A
Somalogic ID (Sequence ID) SL005199 (2730-58_2)
Entrez Gene Symbol MICA
UniProt ID Q29983
UniProt Comment
  • 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.
Biomarker applications (based on IPA annotation)

All locus annotations are based on the sentinel SNP (rs4418214) and 1 proxy variant(s) that is/are in linkage disequilibrium r2 ≥ 0.8. Linkage disequilibrium is based on data from the 1000 Genomes Project, phase 3 version 5, European population and was retrieved using SNiPA's Block Annotation feature.
