PRR3 pseudogene 1 (PRR3P1)

PRR3 pseudogene 1 (PRR3P1) is a human pseudogene, meaning it is a segment of DNA resembling a protein-coding gene (in this case, likely related to PRR3/Proline Rich 3), but carries disabling mutations or structural features that prevent it from encoding a functional protein[1][4][5]. Pseudogenes were once considered genomic "junk," but many are now known to affect biological pathways by regulating their parent genes or participating as competing endogenous RNAs (ceRNAs), antisense RNAs, or sources of small interfering RNAs (siRNAs).[1] However, there is *no evidence that PRR3P1 acts as a therapeutic target, receptor, enzyme, or transporter*. Its relevance is limited to potential regulatory effects typical of pseudogenes in general, not as a functional protein or conventional molecular drug target.[1][4][5] As such, PRR3P1 is **not considered a therapeutic target** and should not be included in structured repositories of actionable drug targets.
