Selenophosphate synthetase 1 pseudogene 1 (SEPHS1P1)

Selenophosphate synthetase 1 pseudogene 1 (SEPHS1P1) is a *non-protein-coding pseudogene* related by sequence to the SEPHS1 gene, which encodes selenophosphate synthetase 1, an enzyme involved in cellular redox homeostasis and indirectly in selenoprotein biosynthesis[1][3]. SEPHS1P1 itself does not code for a functional protein and is not known to have direct biochemical or pharmacological activity. Like many pseudogenes, it could potentially exert regulatory effects on its parental gene's expression at the RNA level—for example, acting as a decoy for microRNAs that would otherwise bind to the functional SEPHS1 transcript[3]. However, there is currently no experimental literature establishing a direct functional or disease relevance specific to SEPHS1P1. In summary: **SEPHS1P1 is a pseudogene, not a functional molecular target.** The functional selenophosphate synthetase 1 gene is SEPHS1—not SEPHS1P1. If you intended to target or study the active enzyme, refer to SEPHS1 and not the pseudogene.
