This gene has 1 transcript (splice variant), 1 gene allele, 542 orthologues, 13 paralogues and is associated with 1 phenotype. Broad expression in lymph node (RPKM 32.9), spleen (RPKM 26.8) and 20 other tissues.

Summary

This gene belongs to the HLA class II alpha chain family. The encoded protein forms a heterodimer with a class II beta chain. It is located in intracellular vesicles and plays a central role in the peptide loading of MHC class II molecules by helping to release the CLIP molecule from the peptide binding site. Class II molecules are expressed in antigen presenting cells (B lymphocytes, dendritic cells, macrophages) and are used to present antigenic peptides on the cell surface to be recognized by CD4 T-cells.
