Protein Information (annotations from UniProt)

Database IDHIV0001947
UniProt IDP55769
Primary gene name(s)SNU13
Synonym gene name(s)NHP2L1
Protein nameNHP2-like protein 1
Protein functionBinds to the 5'-stem-loop of U4 snRNA and may play a role in the late stage of spliceosome assembly. The protein undergoes a conformational change upon RNA-binding. {ECO:0000269|PubMed:10545122, ECO:0000269|PubMed:17412961}.
Subcellular locationNucleus, nucleolus {ECO:0000269|PubMed:10593953, ECO:0000269|PubMed:12429849, ECO:0000269|Ref.7}. Note=Concentrated in the dense fibrillar component of the nucleolus.
