Proteasome subunit alpha 6 pseudogene 4 (PSMA6P4)

Proteasome subunit alpha 6 pseudogene 4 (PSMA6P4) is a processed pseudogene on the human genome that shares sequence similarity with the functional proteasome subunit alpha type-6 (PSMA6) gene[2][5]. Pseudogenes arise from duplication or retrotransposition events and typically accumulate mutations that prevent translation into functional protein, thus lacking the molecular activities of their canonical gene counterparts[8]. PSMA6P4 is annotated but does not have an established biological or clinical role—it is not an active participant in proteasome function nor a target for drugs or diagnostics. If you intended the *functional* protein-coding gene, you should refer to **Proteasome subunit alpha type-6 (PSMA6)**, which is a structural component of the proteasome complex involved in protein degradation, cellular regulation, and is considered a therapeutic target in some disease contexts[1][4][7].

None applicable; as a pseudogene, there is no mechanism of drug action involved.
