Peptidylprolyl isomerase A pseudogene 5 (PPIAP5)

Peptidylprolyl isomerase A pseudogene 5 (PPIAP5) is a non-protein-coding pseudogene in the human genome, classified formally on genetic databases such as NCBI and GeneCards[1][3][5]. PPIAP5 bears sequence similarity to the active gene peptidylprolyl isomerase A (PPIA), which encodes the enzyme cyclophilin A involved in protein folding and is implicated in a range of biological and disease processes[4]. However, PPIAP5 itself does not produce a functional protein and has no known physiological role or therapeutic relevance. It is included in lists of pseudogenes under the caution flag indicating strong suspicion of non-coding status, and its annotation is stable across major databases[2]. There are no known aliases or alternative names beyond PPIAP5, and the gene has not been associated with any disease roles, drug interactions, mechanisms of action, biomarkers, or safety/tolerability issues. It should not be considered a therapeutic target or molecular receptor, and its inclusion in structured target lists would be incorrect[1][2][3][5].

None applicable; there are no pharmaceutical mechanisms targeting PPIAP5[1][3][5].
