Genomic structure, chromosomal localization, and expression of human cathepsin W.
A 12 kb genomic fragment containing the entire open reading frame of the human cathepsin W was isolated and the genomic organization of this papain-like protease gene was determined. The 3.8 kb gene was mapped by fluorescence in situ hybridization to chromosome 11q13.1. The gene contained ten exons with introns ranging from 81 to 1119 bp. Four of the nine introns and a 5' untranslated exon were conserved when compared to related genes such as cathepsins L, K and S, whereas there was no similarity to the genomic organization of cathepsins B or C. In contrast to conserved splice site locations in other cysteine protease family members, the cathepsin W gene contained five unique locations. Furthermore, human cathepsin W cDNA was expressed, and was found to be localized within the rough endoplasmic reticulum in transiently transfected Cos-7 and Hela cells.
