01
Overview
RNU1-33P (RNA, U1 small nuclear 33, pseudogene) is classified as a pseudogene of the U1 small nuclear RNA family. U1 small nuclear RNAs are integral to the function of the spliceosome in pre-mRNA splicing, but pseudogenes like RNU1-33P are characterized by sequence deviations (mutations, deletions, insertions) preventing them from encoding fully functional RNA molecules. Some U1 snRNA pseudogenes are transcriptionally active and may generate variant snRNAs capable of forming ribonucleoprotein complexes and exerting regulatory roles in specific cellular contexts, but the specific biological or pathological relevance of RNU1-33P itself has not been characterized. Karyotypically, it is located at 13q33.1 as annotated by HGNC[5]. No therapeutic interventions or disease associations are documented for this pseudogene[1][4][5][6].

02
Mechanism of action
Not applicable; no drugs target RNU1-33P
03
Biological functions
None established for RNU1-33P specifically. The functional U1 snRNAs participate in pre-mRNA splicing as part of the spliceosome, but most pseudogenes do not encode functional snRNA; some variant U1 pseudogenes may be transcribed and have potential regulatory functions, but these roles remain largely uncharacterized.
04
Disease associations
None known for RNU1-33P. No established role in disease. Variant U1 snRNAs have been implicated in RNA processing in development or cancer, but RNU1-33P itself has no documented association.
