Major histocompatibility complex, class II, DP alpha 1

n/an/an/an/anan/an/an/an/an/aMajor histocompatibility complex, class II, DP alpha 1, also known as HLA-DPA1, is a human gene.

[1] The protein encoded by this gene belongs to the HLA class II alpha chain paralogues.

The class II molecule is a heterodimer consisting of an alpha (DPA) and a beta chain (DPB), both anchored in the membrane.

It plays a central role in the immune system by presenting peptides derived from extracellular proteins.
