RNA, U4 small nuclear 64, pseudogene (RNU4-64P)

RNU4-64P represents a predicted pseudogene related to U4 small nuclear RNA but does not encode a functional RNA or protein product[4]. In humans, there are multiple U4 small nuclear RNA genes (such as RNU4-1, RNU4-2, etc.), which are bona fide non-coding RNAs that play critical roles in the formation of the spliceosome—the complex responsible for removing introns from pre-mRNA. However, RNU4-64P is annotated as a pseudogene and not expressed as a functional molecule. Its sequence is similar to U4 snRNA genes but it does not contribute to spliceosome activity, does not have established biological function, is not implicated in disease as an active element, and does not interact with drugs or serve as a biomarker[4]. There is extensive recent research describing RNU4-2, a related gene that encodes functional U4 snRNA and is involved in pre-mRNA splicing, neurodevelopmental disorders (e.g., ReNU syndrome), and spliceosomal machinery[1][2][3][5][6][7]. However, RNU4-64P does not share these characteristics and is not considered a therapeutic target nor a functional gene product. Issues with this target: - RNU4-64P is a pseudogene (not a functional target); - No evidence of protein or functional RNA product; - No therapeutic relevance or role in disease as a target; - Not a receptor, enzyme, transporter, nor molecule relevant for drug targeting; - Query may be conflating pseudogene with canonical U4 snRNA genes that are functionally characterized (e.g., RNU4-2)[1][2][3][5][6][7]. If you intended to reference the active snRNA gene related to U4—which is a functional spliceosomal RNA and significant in disease—the correct molecular target is "RNA, U4 small nuclear 2" (RNU4-2), not the pseudogene RNU4-64P[1][2][3][5][6][7].
