Ribosomal protein SA pseudogene 75 (RPSAP75)

Ribosomal protein SA pseudogene 75 (RPSAP75) is an annotated human pseudogene located on chromosome 9. Pseudogenes like RPSAP75 typically do not encode functional proteins; instead, they are remnants or non-functional copies of related protein-coding genes (in this case, RPSA). There is no published functional characterization for RPSAP75, and available data from gene resources confirm only its annotated genomic location and status as a processed pseudogene[4][5][6]. Pseudogenes can sometimes have regulatory roles as non-coding RNAs, but there is currently no evidence for such a function for RPSAP75 specifically. RPSA, the gene family it is related to, is a multifunctional protein significant in various processes (such as acting as a laminin receptor and being involved in cancer progression), but these functions do not apply to RPSAP75[1][3]. RPSAP75 is a non-functional pseudogene and not a therapeutic target or active protein. It is recorded only as a pseudogene in major biological databases, with no evidence of protein product, therapeutic interest, or functional role[4][5][6].
