title: Mouse neurotensin receptor 2 gene (Ntsr2): genomic organization, transcriptional regulation and genetic mapping on chromosome 12.
abstract: We earlier isolated and characterized the mouse neurotensin receptor 1 (Ntsr1) gene and developed Ntsr1 null mice. In the present study, we isolated the mouse neurotensin receptor 2 gene (Ntsr2) and characterized the structure. The gene fragments available to us have 1.1 kb of 5' upstream promoter region and a 7 kb coding region composed of four exons. Transcription initiation sites, determined by primer extension analysis, are located at 286 and 303 bp upstream from initiation of the ATG codon. The promoter region contains a TATA-like box, a typical CAAT box and putative GATA-2, CREB, Oct-2 and Ikarous 2 binding elements. We also found novel splice donor-acceptor sites for alternative splicing, which could generate a short form of mRNA encoding a truncate-type receptor. In addition, we determined the chromosomal location of the Ntsr2 gene and mapped it at 6 cM from the centromere on chromosome 12.
