Also known as: FA1; FA-1; NHPX; 15.5K; OTK27; SSFA1; NHP2L1; SPAG12; SNRNP15-5
Summary: Originally named because of its sequence similarity to the Saccharomyces cerevisiae NHP2 (non-histone protein 2), this protein appears to be a highly conserved nuclear protein that is a component of the [U4/U6.U5] tri-snRNP. It binds to the 5' stem-loop of U4 snRNA. Two transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Jul 2008]

What's a GeneRIF?

Results solve the structure of a complex resulting from interaction between protein fragments of human NUFIP1 and its cofactor ZNHIT3, and emphasize their imbrication. Also, it seems that the complexes involving NUFIP1, ZNHIT3, and SNU13 share strong structural similarities between human and yeast, suggesting that the initial steps of the box C/D snoRNP assembly process are conserved among species.

Data show that binding of the 15.5 kD RNA binding protein to the box C/D motif of snoRNAs is essential for the association of other snoRNP-associated proteins.
Title: Conserved stem II of the box C/D motif is essential for nucleolar localization and is required, along with the 15.5K protein, for the hierarchical assembly of the box C/D snoRNP.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
