BAIT

HRR25

KTI14, serine/threonine protein kinase HRR25, L000000810, YPL204W
Protein kinase; involved in regulating diverse events including vesicular trafficking, DNA repair, and chromosome segregation; binds the CTD of RNA pol II; phosphorylates the COPII coat; phosphorylates Tif6p which plays a critical role in 60S ribosomal subunit biogenesis; interacts with Sit4p phosphatase; homolog of mammalian casein kinase 1delta (CK1delta)
Saccharomyces cerevisiae (S288c)
PREY

RPS3

SUF14, ribosomal 40S subunit protein S3, rp13, YS3, S3, L000002161, L000001749, YNL178W
Protein component of the small (40S) ribosomal subunit; has apurinic/apyrimidinic (AP) endonuclease activity; essential for viability; homologous to mammalian ribosomal protein S3 and bacterial S3
Saccharomyces cerevisiae (S288c)

Biochemical Activity (Phosphorylation)

An interaction is inferred from the biochemical effect of one protein upon another, for example, GTP-GDP exchange activity or phosphorylation of a substrate by a kinase. The bait protein executes the activity on the substrate hit protein. A Modification value is recorded for interactions of this type with the possible values Phosphorylation, Ubiquitination, Sumoylation, Dephosphorylation, Methylation, Prenylation, Acetylation, Deubiquitination, Proteolytic Processing, Glucosylation, Nedd(Rub1)ylation, Deacetylation, No Modification, Demethylation.

The formation of eukaryotic ribosomes is a multistep process that takes place successively in the nucleolar, nucleoplasmic and cytoplasmic compartments. Along this pathway, multiple pre-ribosomal particles are generated, which transiently associate with numerous non-ribosomal factors before mature 60S and 40S subunits are formed. However, most mechanistic details of ribosome biogenesis are still unknown. Here we identify a maturation step of ... [more]
