Peptidylprolyl isomerase A pseudogene 47 (PPIAP47)

Peptidylprolyl isomerase A pseudogene 47 (PPIAP47) is classified as a pseudogene, meaning it is a nonfunctional segment of DNA that closely resembles the functional PPIA (peptidylprolyl isomerase A) gene but is not translated into a functional protein[1][2][6]. PPIAP47 is found in the human genome but lacks the ability to produce an active enzyme or serve as a direct molecular target for therapeutics. Pseudogenes like PPIAP47 may still have genetic or regulatory functions under some circumstances, such as acting as decoys for regulatory RNAs, but no functional or disease relevance has been demonstrated specifically for PPIAP47 to date[4][6]. The canonical abbreviation PPIAP47 should not be confused with the enzyme peptidylprolyl isomerase A (PPIA or cyclophilin A), which is a bona fide therapeutic target with a range of biological and pathological roles[3][5].
