Genomic organization and 5'-flanking DNA sequence of the murine stomatin gene (Epb72).

Stomatin is a poorly understood integral membrane protein that is absent from the erythrocyte membranes of many patients with hereditary stomatocytosis. This report describes the cloning of the murine stomatin chromosomal gene, determination of its genomic structure, and characterization of the 5'-flanking genomic DNA sequences. The stomatin gene is encoded by seven exons spread over approximately 25 kb of genomic DNA. There is no concordance between the exon structure of the stomatin gene and the locations of three domains predicted on the basis of protein structure. Inspection of the 5'-flanking DNA sequences reveals features of a TATA-less housekeeping gene promoter and consensus sequences for a number of potential DNA-binding proteins.
