title: Chromosomal localization of the human urothelial "tetraspan" gene, UPK1B, to 3q13.3-q21 and detection of a TaqI polymorphism.
abstract: The TI1/UPK1b gene codes for a protein of the "tetraspan" family and is expressed as a differentiation product of the mammalian urothelium. A partial genomic clone of the human homologue of the TI1/UPK1b gene was isolated and used as probe to localize the human gene to chromosome 3q13.3-q21 by in situ hybridization. Using the same probe, a TaqI restriction fragment length polymorphism, with 29% heterozygosity, was identified by Southern analysis.
