cystatin 12, pseudogene (CST12P)

Cystatin 12, pseudogene (CST12P) is a non-protein-coding sequence in the cystatin gene family. Pseudogenes like CST12P share sequence similarity with active cystatin genes, which are known inhibitors of cysteine proteases, but CST12P itself cannot produce a functional protein due to genetic disruptions. As such, CST12P does not participate in known biological processes or disease mechanisms and is not a molecular drug target. The numerous alternative names reflect historical and bioinformatics annotation practices rather than distinct biological functions. All functional and clinical roles described in the search results for cystatin family members refer to protein-coding genes such as CST3 (cystatin C) or other functional cystatins, not to CST12P or other pseudogenes. In databases and literature, pseudogenes are often listed due to sequence homology but do not have actionable pharmacological or diagnostic significance.
