PTP4A1 pseudogene 1 (PTP4A1P1)

PTP4A1 pseudogene 1 (PTP4A1P1) is a processed pseudogene related to the PTP4A1 (Protein Tyrosine Phosphatase 4A1) gene family. Pseudogenes such as PTP4A1P1 arise from duplications or retrotranspositions of a functional gene but have typically lost the ability to encode a functional protein due to mutations, deletions, or the accumulation of stop codons[4]. Multiple pseudogenes for PTP4A1 are found on several chromosomes, but these do not produce functional protein and are generally not transcribed or translated[4]. PTP4A1 itself is a protein tyrosine phosphatase involved in cell signaling, proliferation, migration, and cancer, but pseudogenes like PTP4A1P1 have no confirmed biological function, and no data support their use as therapeutic targets, disease biomarkers, or drug interaction partners[1][4]. Key clarifications: - PTP4A1P1 refers specifically to a pseudogene—not to the functional PTP4A1 protein (which is also known as PRL-1, Protein Tyrosine Phosphatase 4A1, etc.)[1][3][4]. - Pseudogenes are not therapeutic targets since they do not encode active proteins involved in disease pathways or cellular physiology[4]. - Since this is a pseudogene, most categories (biological function, disease role, interacting drugs, etc.) are not applicable. If a therapeutic protein target is desired, refer to Protein tyrosine phosphatase type IVA 1 (PTP4A1, PRL-1), not the pseudogene[1][2][3]. For "PTP4A1 pseudogene 1," the entry is marked incorrect for target selection purposes.
