Molecular Cloning and Complete cDNA Sequence of UBH1 in Mouse Testis

We have identified a full-length mouse UBH1 cDNA, encoding a putative deubiquitinating enzyme, from the testis by RT-PCR using primers prepared from sequences conserved amongst deubiquitinating enzymes. Sequence analysis predicts that the UBH1 cDNA encodes a 355 amino acid polypeptide with the molecular weight of approximately 39 kDa containing the highly conserved Cys, Asp, and His domains characteristic of the ubiquitin-specific processing proteases. Biochemical assay revealed that the mouse UBH1 has deubiquitinating enzyme activity and sequence analysis showed 98.3 % amino acid identity with human UBH1
