114-334aa, Full Length of Mature Protein. MW: 37,329 Da. Purity >85% (SDS-PAGE). This protein, a member of the peptidase C1 family, is a lysosomal cysteine proteinase that may play an important role in corneal physiology. This gene is expressed in colorectal and breast carcinomas but not in normal colon, mammary gland, or peritumoral tissues, suggesting a possible role for this gene in tumor processes.
