Cathepsin Z preproprotein, Cathepsin Z, CTSX, Cathepsin P, Cathepsin X, CTSZ, Cathepsin-Z.

Cathepsin-Z (CTSZ) is a lysosomal cysteine proteinase and member of the peptidase C1 family. CTSZ, which has been also known as cathepsin X and cathepsin P, exhibits carboxy-monopeptidase and carboxy-dipeptidase activities. CTSZ is expressed ubiquitously in cancer cell lines and primary tumors and, similar to other members of this family, takes part in tumorigenesis.

CTSZ Human Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 265 amino acids (62-303) and having a molecular mass of 29.5kDa.
CTSZ is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
