Ribosomal protein SA pseudogene 67 (RPSAP67)

Ribosomal protein SA pseudogene 67 (RPSAP67) is a processed pseudogene annotated in the genome as related to the functional ribosomal protein SA (RPSA) gene[4][3][7]. RPSA itself is a multifunctional protein, acting as a ribosomal subunit, cell surface receptor, and mediator of numerous biological processes including cell adhesion and pathogenesis in cancer and prion diseases[1][5][7]. However, RPSAP67 is not transcribed into a functional protein and does not serve as a biological target. There are many such RPSA-related pseudogenes across vertebrate genomes that can complicate genetic studies but have no independent biological or clinical significance[3][4][7]. Pseudogenes like RPSAP67 are DNA sequences similar to known genes but lack coding potential due to mutations or missing regulatory elements. The functional RPSA/67LR protein is therapeutically relevant, but this is not true for its pseudogenes. No literature supports roles for RPSA pseudogenes (such as RPSAP67) as disease modifiers, biomarkers, or drug targets in human health and therapeutics[3][4][7]. If your intended target is the biologically active **ribosomal protein SA/67 kDa laminin receptor (RPSA, 67LR, 37LRP)**, that is a recognized therapeutic and research target, distinct from RPSAP67[1][5][7].
