Mediator complex subunit 28 pseudogene 7 (MED28P7)

Mediator complex subunit 28 pseudogene 7 (MED28P7) is a human processed pseudogene related to the MED28 gene, which itself encodes a component of the Mediator complex, a multi-protein complex involved in transcriptional regulation by RNA polymerase II[1][5][7]. MED28P7 is not known to encode a protein nor to serve any canonical enzymatic, receptor, or transporter role. However, recent research in related ribosomal protein pseudogenes suggests some pseudogenes may regulate the expression of their parental genes at the RNA level, possibly by acting as competing endogenous RNAs (ceRNAs) that “sponge” microRNAs and alter the survival or prognosis of cancer patients when overexpressed[2]. For example, the RPS28P7 pseudogene has been implicated as a potential prognostic marker in pancreatic cancer by association with altered mRNA levels and outcomes, but no evidence exists for similar mechanistic or clinical significance for MED28P7 itself[2]. As such, MED28P7 should **not** be considered a direct molecular target for therapeutic intervention, and its name, structure, and biology should be noted as problematic in target selection pipelines: it is a pseudogene and not a meaningful drug target[1][7]. Summary judgment: MED28P7 is a *pseudogene*, not a classical target, has no protein product, and only theoretical or indirect biological significance. It is not an established or credible drug target. If MED28P7 appears in drug or biology pipelines, its presence likely reflects a data error, misannotation, or misinterpretation of biological significance. It should be labeled as *incorrect* in target frameworks[1][2][7].

None known (pseudogenes do not encode proteins or classical druggable targets)
