  • Title: Mouse cathepsin F: cDNA cloning, genomic organization and chromosomal assignment of the gene.
    Author: Deussing J, Tisljar K, Papazoglou A, Peters C.
    Journal: Gene; 2000 Jun 27; 251(2):165-73. PubMed ID: 10876093.
    Abstract:
    A murine cysteine protease of the papain family was identified by dbEST-database search. A 1.87kb full-length cDNA encoding a predicted polypeptide of 462 amino acids was sequenced. Since the encoded polypeptide shows more than 80% sequence identity with human cathepsin F, it is most likely that this cDNA represents the murine homologue of cathepsin F, and it was therefore named accordingly. Murine cathepsin F exhibits a domain structure typical for papain-like cysteine proteases, a 20 amino acid N-terminal hydrophobic signal sequence followed by an extraordinarily long propeptide of 228 amino acids and the domain of the mature protease comprising 214 amino acids. The mature region contains all features characteristic of a papain-like cysteine protease, including the highly conserved cysteine, histidine and asparagine residues of the 'catalytic triad'. Genomic clones covering the murine cathepsin F gene were isolated. The mouse cathepsin F gene consists of 14 exons and 13 introns and spans 5.8kb. Murine cathepsin F was mapped to chromosome 19, a region with synteny homology to a region of human chromosome 11 to which human cathepsin F has been mapped previously. Northern blot analysis of RNA from multiple tissues revealed a ubiquitous expression of cathepsin F in mouse and man.
