Human Leukocyte Antigen Class I Histocompatibility Antigen Alpha Chain A*02 (HLA-A*02)

Target
HLA-A*02
Molecular classification
MHC class I molecule, Transmembrane glycoprotein, Histocompatibility antigen
01

Overview

HLA-A*02 is a specific allele group within the HLA-A locus, encoding a major histocompatibility complex (MHC) class I molecule. It presents intracellular peptides to CD8+ T lymphocytes, playing a crucial role in immune surveillance. HLA-A*02 is expressed on nearly all nucleated cells and is critical for tissue compatibility testing in organ transplantation. It is also associated with susceptibility to various infectious and autoimmune diseases.
