Argininosuccinate synthetase 1 pseudogene 4 (ASS1P4)

Argininosuccinate synthetase 1 pseudogene 4 (ASS1P4) is classified as a pseudogene in the human genome[1]. Pseudogenes are genomic DNA sequences similar to functional genes but nonfunctional due to mutations or lack of regulatory elements. ASS1P4 shares sequence similarity with the *argininosuccinate synthetase 1* (ASS1) gene, which encodes an enzyme critical for the urea cycle and arginine biosynthesis. However, unlike ASS1, ASS1P4 does not produce a functional protein and has no established biological function, disease association, or role as a drug target. Its presence reflects evolutionary duplication events, and it serves no current therapeutic or biomarker purpose[1].\n\nIf you intended the functional enzyme *argininosuccinate synthetase 1* (ASS1), please specify, as that protein is clinically and pharmacologically relevant[2][3][4][5][6][7][8].
