How this entity was disambiguated
This entity first appeared as the object of triple T22692665 — 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: U4 snRNP Context triple: [Sm proteins, isComponentOf, U4 snRNP]
-
A.
U1 snRNP
U1 snRNP is a small nuclear ribonucleoprotein complex essential for recognizing the 5′ splice site and initiating pre-mRNA splicing in eukaryotic cells.
-
B.
U2 snRNP
U2 snRNP is a small nuclear ribonucleoprotein complex that recognizes the branch point sequence in pre-mRNA and plays a key role in spliceosome-mediated RNA splicing.
-
C.
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.
-
D.
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.
-
E.
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.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
