RNA, U2 small nuclear 45, pseudogene (RNU2-45P)

**RNA, U2 small nuclear 45, pseudogene (RNU2-45P)** is classified as a *pseudogene* in the human genome[1][6]. It is a member of the RNU2 family, which includes genes encoding U2 small nuclear RNA (snRNA), a key RNA component of the spliceosome complex responsible for pre-mRNA splicing[1]. However, as a pseudogene, RNU2-45P is not known to produce a functional RNA or protein product, nor does it have a defined biological or disease role. It is annotated in gene databases purely as a non-coding, likely non-functional genomic element[1][6].\n\n**Essential context and supporting details:**\n- Unlike functional RNU2 genes (such as RNU2-2, which encode snRNA components of the spliceosome[5]), *RNU2-45P* is specifically labeled as a pseudogene, suggesting it was once functional but has lost its ability to express a functional product[1][6].\n- There is no evidence of its use as a therapeutic target, diagnostic biomarker, or role in disease.\n- Its only established classification is "Other," denoting it as a pseudogene within the non-coding RNA gene family.\n\nNo information was identified regarding interacting drugs, pathways, clinical relevance, or safety concerns[1][6]. If more detailed mapping is required (e.g., for the parent U2 snRNA family or spliceosomal components), this must be searched under the appropriately functional genes, not RNU2-45P.
