Peptidylprolyl isomerase A pseudogene 41 (PPIAP41)

Peptidylprolyl isomerase A pseudogene 41 (PPIAP41) is a DNA sequence related to the PPIA gene (encoding cyclophilin A), classified as a pseudogene. Unlike its protein-coding parent, PPIAP41 does not produce a functional protein and is not recognized as a direct therapeutic target. While some pseudogenes can act as long non-coding RNAs with regulatory functions or serve as competitive endogenous RNAs sponging miRNAs, there is no documented evidence or research specifically characterizing PPIAP41’s biological role, therapeutic relevance, or disease associations. As such, PPIAP41's main classification in genomic databases is as a non-coding pseudogene, and it is not considered a classical target in drug discovery[5][2].
