NAF1 | nuclear assembly factor 1 homolog (S. cerevisiae); RNA-binding protein required for the maturation of box H/ACA snoRNPs complex and ribosome biogenesis.

SHQ1 | SHQ1 homolog (S. cerevisiae); Required for the quantitative accumulation of H/ACA ribonucleoproteins (RNPs), including telomerase, probably through the stabilization of DKC1, from the time of its synthesis until its association with NOP10, NHP2, and NAF1 at the nascent H/ACA RNA (577 aa) | |||
KRI1 | KRI1 homolog (S. cerevisiae) (709 aa) | |||
NOP10 | NOP10 ribonucleoprotein homolog (yeast); Required for ribosome biogenesis and telomere maintenance. Part of the H/ACA small nucleolar ribonucleoprotein (H/ACA snoRNP) complex, which catalyzes pseudouridylation of rRNA.

PDCD11 | programmed cell death 11; Essential for the generation of mature 18S rRNA, specifically necessary for cleavages at sites A0, 1 and 2 of the 47S precursor. Directly interacts with U3 snoRNA (1871 aa) | |||
RRP12 | ribosomal RNA processing 12 homolog (S. cerevisiae) (1297 aa) | |||
NCBP1 | nuclear cap binding protein subunit 1, 80kDa; Component of the cap-binding complex (CBC), which binds cotranscriptionally to the 5’-cap of pre-mRNAs and is involved in various processes such as pre-mRNA splicing, translation regulation, nonsense-mediated mRNA decay, RNA-mediated gene silencing (RNAi) by microRNAs (miRNAs) and mRNA export. The CBC complex is involved in mRNA export from the nucleus via its interaction with ALYREF/THOC4/ALY, leading to the recruitment of the mRNA export machinery to the 5’-end of mRNA and to mRNA export in a 5’ to 3’ direction through the nuclear pore.
