HGNC Approved Gene Symbol: PAQR9
Cytogenetic location: 3q23 Genomic coordinates (GRCh38): 3:142,949,164-142,964,008 (from NCBI)
By searching databases for sequences encoding a 7-transmembrane domain similar to those of ADIPOR1 (607945) and ADIPOR2 (607946), Tang et al. (2005) identified PAQR9. The deduced 377-amino acid protein shares significant similarity with ADIPOR1 and ADIPOR2 only in the central 7-transmembrane domain region. Database analysis revealed a mouse ortholog, which shares 91% amino acid identity with human PAQR9. RT-PCR analysis detected high PAQR9 expression in human brain, testis, liver, heart, and adult bone marrow. Weaker expression was detected in pancreas, lymph node, kidney, skin, and thymus, and little to no expression was detected in other tissues examined.
Tang et al. (2005) determined that the PAQR9 gene contains a single coding exon.
By genomic sequence analysis, Tang et al. (2005) mapped the PAQR9 gene to chromosome 3q23.
