How this entity was disambiguated
This entity first appeared as the object of triple T22692663 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Target entity: U1 snRNP Context triple: [Sm proteins, isComponentOf, U1 snRNP]
-
A.
U4 snRNA
U4 snRNA is a small nuclear RNA component of the spliceosome that pairs with U6 snRNA to help mediate pre-mRNA splicing in eukaryotic cells.
-
B.
fibrillarin
Fibrillarin is a highly conserved nucleolar protein that functions as a core component of small nucleolar ribonucleoproteins (snoRNPs), playing a key role in rRNA processing and ribosome biogenesis.
-
C.
Rpb7 subunit
The Rpb7 subunit is a conserved protein component of eukaryotic RNA polymerase II that forms a subcomplex with Rpb4 and plays key roles in transcription initiation, elongation, and mRNA processing.
-
D.
Rpb9 subunit
The Rpb9 subunit is a small accessory component of eukaryotic RNA polymerase II that contributes to transcription fidelity and proper enzyme function.
-
E.
RNA polymerase II
RNA polymerase II is the eukaryotic enzyme complex responsible for transcribing DNA into messenger RNA and many non-coding RNAs, playing a central role in gene expression.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
