Human Leukocyte Antigen DR Beta Chain (HLA-DRβ)

Target
HLA-DRβ
Molecular classification
MHC Class II, Receptor
01

Overview

The human leukocyte antigen DR beta chain (HLA-DRβ) is a protein encoded by the HLA-DRB1 gene. It is a component of the HLA-DR molecule, a MHC class II protein that presents peptide antigens to T helper cells, initiating and regulating immune responses. HLA-DRβ is highly polymorphic, influencing disease susceptibility and transplant compatibility.
