About HHLA2

Cytogenetic location: 3q13.13 Genomic coordinates (GRCh38): 3:108,296,548-108,378,285 (from NCBI)

This gene has 9 transcripts (splice variants), 101 orthologues and 15 paralogues. Biased expression in small intestine (RPKM 36.3), colon (RPKM 25.6) and 4 other tissues.

Summary

This gene encodes a protein ligand found on the surface of monocytes. The encoded protein is thought to regulate cell-mediated immunity by binding to a receptor on T lymphocytes and inhibiting the proliferation of these cells. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Sep 2013]
