SSB-1 of the yeast Saccharomyces cerevisiae is a nucleolar-specific, silver-binding protein that is associated with the snR10 and snR11 small nuclear RNAs [PDF]
, 1990 SSB-1, the yeast single-strand RNA-binding protein, is demonstrated to be a yeast nucleolar-specific, silver-binding protein. In double-label immunofluorescence microscopy experiments antibodies to two other nucleolar proteins, RNA Pol I 190-kD and ...

Mud2 functions in transcription by recruiting the Prp19 and TREX complexes to transcribed genes [PDF]
, 2007 The different steps of gene expression are intimately linked to coordinate and regulate this complex process. During transcription, numerous RNA-binding proteins are already loaded onto the nascent mRNA and package the mRNA into a messenger ...

U1 snRNP regulates cancer cell migration and invasion in vitro
Nature Communications, 2020 U1 snRNP is a key regulator of mRNA biogenesis through its roles in splicing, and transcription and 3’-end processing. Here the authors show a tumor suppressor-like function of U1 snRNP using in vitro cell migration/invasion assays and transcriptome ...

Keratinocyte differentiation-dependent human papillomavirus gene regulation [PDF]
, 2017 Human papillomaviruses (HPVs) cause diseases ranging from benign warts to invasive cancers. HPVs infect epithelial cells and their replication cycle is tightly linked with the differentiation process of the infected keratinocyte.

p110, a novel human U6 snRNP protein and U4/U6 snRNP recycling factor [PDF]
The EMBO Journal, 2002 During each spliceosome cycle, the U6 snRNA undergoes extensive structural rearrangements, alternating between singular, U4-U6 and U6-U2 base-paired forms. In Saccharomyces cerevisiae, Prp24 functions as an snRNP recycling factor, reannealing U4 and U6 snRNAs.

In Vitro Studies of the Prp9·Prp11·Prp21 Complex Indicate a Pathway for U2 Small Nuclear Ribonucleoprotein Activation [PDF]
, 1996 Pre-mRNA splicing takes place on a large ribonucleoprotein particle, the spliceosome which contains the five small nuclear ribonucleoproteins (snRNPs), U1, U2, U4, U5, and U6. In Saccharomyces cerevisiae the mRNA splicing factors, Prp9, Prp11, and Prp21,

Involvement of U1 Small Nuclear Ribonucleoproteins (snRNP) in 5′ Splice Site-U1 snRNP Interaction [PDF]
Journal of Biological Chemistry, 1996 U1 small nuclear ribonucleoprotein (snRNP) is an important ribonucleoprotein involved early in the spliceosome formation to commit pre-mRNAs to the splicing pathway. We have determined the association and dissociation kinetics of the 5' splice site-U1 snRNP interaction using purified U1 snRNP and a short RNA oligonucleotide comprising the 5' splice ...

Identification of a PRPF4 loss-of-function variant that abrogates U4/U6.U5 tri-snRNP integration and is associated with retinitis pigmentosa. [PDF]
PLoS ONE, 2014 Pre-mRNA splicing by the spliceosome is an essential step in the maturation of nearly all human mRNAs. Mutations in six spliceosomal proteins, PRPF3, PRPF4, PRPF6, PRPF8, PRPF31 and SNRNP200, cause retinitis pigmentosa (RP), a disease characterized by ...

αCP binding to a cytosine-rich subset of polypyrimidine tracts drives a novel pathway of cassette exon splicing in the mammalian transcriptome. [PDF]
, 2016 Alternative splicing (AS) is a robust generator of mammalian transcriptome complexity. Splice site specification is controlled by interactions of cis-acting determinants on a transcript with specific RNA binding proteins.
