What's a GeneRIF?

LncRNA SNORD3A specifically sensitizes breast cancer cells to 5-FU by sponging miR-185-5p to enhance UMPS expression.
Title: LncRNA SNORD3A specifically sensitizes breast cancer cells to 5-FU by sponging miR-185-5p to enhance UMPS expression.
Data show that U3 snoRNP assembly, and therefore U3 snoRNA accumulation, is regulated through the U3-specific protein hU3-55K.
Title: A weak C' box renders U3 snoRNA levels dependent on hU3-55K binding.
U3 snoRNP is assembled and matures in the nucleoplasm in a large dynamic multiprotein complex

PHAX and CRM1 have roles in transporting U3 snoRNA to nucleoli
Title: PHAX and CRM1 are required sequentially to transport U3 snoRNA to nucleoli.

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.
