Mapping of the P2U purinergic receptor gene to human chromosome 11q13.5-14.1

We mapped a human P2U purinergic receptor gene to chromosome 11q13.5-14.1. Oligonucleotide primers complementary to a part of the human P2U purinergic receptor cDNA were used to amplify a region from genomic DNAs from a panel of mouse/human somatic cell hybrid cell lines, each containing a single human chromosome. A PCR product of the expected size (378 bp) resulted from a single hybrid cell fine containing human chromosome II. The gene was further localized to a region of chromosome II using a sub-chromosomal hybrid panel containing different segments of chromosome II. Based on the specific PCR product obtained and its Southern hybridization to the P2U receptor cDNA, the human P2U receptor gene was localized to chromosome 11q13.5-14.1.
