Phosphoribosylaminoimidazole carboxylase, phosphoribosylaminoimidazole succinocarboxamide synthetase pseudogene 4 (PAICSP4)

Phosphoribosylaminoimidazole carboxylase, phosphoribosylaminoimidazole succinocarboxamide synthetase pseudogene 4" (PAICSP4) is annotated as a pseudogene, not as a functional protein-coding gene. It is derived from genes involved in purine biosynthesis (likely from genes PAICS or similar), but does not produce a functional product and is not considered a therapeutic target, enzyme, receptor, transporter, or other druggable molecule. It has no defined molecular function, disease association, or pharmacological relevance. Its listing as a combined, compound name followed by "pseudogene 4" strongly suggests a database artifact, misannotation, or a nonstandard entry. If you require detailed information on the actual enzymes (not the pseudogene) from which this pseudogene is derived—such as phosphoribosylaminoimidazole carboxylase or phosphoribosylaminoimidazole succinocarboxamide synthetase—please specify, as those are functional enzymes in purine biosynthesis.
