Human leukocyte antigen A classical class I family consists of three members including HLA-A, HLA-B and HLA-C. Members of classical class I major histocompatibility complex (MHC) contain a peptide bound to a transmembrane glycoprotein subunit, the heavy chain, in association with a soluble light chain called β2-microglobulin. Class I MHC are present in changeable volumes on all nucleated cells.
The antibody MEM-81 reacts with human classical MHC Class I molecules in native cell-surface forms. MHC Class I molecules (MHC Class Ia) are expressed on the surface of human nucleated cell types.
The previously assigned protein identifier P01891 has been merged into P04439. Full details can be found on the UniProt database.

생화학적/생리학적 작용
Human leukocyte antigen A class I downregulation is implicated in tumor invasion and development. Genetic variations in the class I major histocompatibility complex (MHC) is associated with the development of melanoma. HLA-viral peptide interaction plays a major role in the regulation of human immunodeficiency virus (HIV) infection.
