KCTD5 pseudogene 1 (KCTD5P1)

KCTD5 pseudogene 1 (KCTD5P1) is a non-protein-coding pseudogene related to the KCTD5 gene, which encodes a cytosolic adaptor protein involved in protein ubiquitination and neuronal signaling. Pseudogenes like KCTD5P1 generally do not produce functional proteins and are not considered therapeutic targets. Current databases and scientific literature do not support any direct molecular, biological, or clinical role for KCTD5P1[3]. The functional, protein-coding gene KCTD5 (not KCTD5P1) has roles in neuronal cAMP signaling and cell death regulation, and is being investigated as a cancer biomarker and for its role in protein ubiquitination[1][2][4]. However, KCTD5P1 is not KCTD5. Pseudogenes may serve as sources for RNA or regulatory elements in rare cases, but no such function is reported for KCTD5P1. KCTD5P1 is not a valid molecular target; it is a non-functional pseudogene and should not be used in therapeutic or biomarker research or as a structured molecular entity[3]. If you intend to refer to the functional potassium channel tetramerization domain-containing protein 5, you should consider "KCTD5," not "KCTD5P1."
