About BTN3A3

Cytogenetic location: 6p22.2 Genomic coordinates (GRCh38): 6:26,440,504-26,453,415 (from NCBI)

This gene has 15 transcripts (splice variants), 41 orthologues and 15 paralogues. Ubiquitous expression in spleen (RPKM 36.1), lymph node (RPKM 22.4) and 24 other tissues.

Summary

The butyrophilin (BTN) genes are a group of major histocompatibility complex (MHC)-associated genes that encode type I membrane proteins with 2 extracellular immunoglobulin (Ig) domains and an intracellular B30.2 (PRYSPRY) domain. Three subfamilies of human BTN genes are located in the MHC class I region: the single-copy BTN1A1 gene (MIM 601610) and the BTN2 (e.g., BTN2A1; MIM 613590) and BTN3 (e.g., BNT3A3) genes, which have undergone tandem duplication, resulting in 3 copies of each (summary by Smith et al., 2010 [PubMed 20208008]).[supplied by OMIM, Nov 2010]
