WHI3 protein (Saccharomyces cerevisiae) - STRING interaction network
"WHI3" - RNA binding protein that sequesters CLN3 mRNA in cytoplasmic foci in Saccharomyces cerevisiae
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
some 3D structure is known or predicted
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
protein homology

WHI3RNA binding protein that sequesters CLN3 mRNA in cytoplasmic foci; cytoplasmic retention factor for Cdc28p and associated cyclins; regulates cell fate and dose-dependently regulates the critical cell size required for passage through Start; Involved in size control and cell cycle (661 aa)    
Predicted Functional Partners:
G1 cyclin involved in cell cycle progression; activates Cdc28p kinase to promote the G1 to S phase transition; plays a role in regulating transcription of the other G1 cyclins, CLN1 and CLN2; regulated by phosphorylation and proteolysis; Essential for the control of the cell cycle at the G1/S (start) transition. CLN3 may be an upstream activator of the G1 cyclins which directly catalyze start (580 aa)
Catalytic subunit of the main cell cycle cyclin-dependent kinase (CDK); alternately associates with G1 cyclins (CLNs) and G2/M cyclins (CLBs) which direct the CDK to specific substrates; This protein is essential for the completion of the start, the controlling event, in the cell cycle. More than 200 substrates have been identified (298 aa)
RNase of the DEDD superfamily, subunit of the Ccr4-Not complex that mediates 3’ to 5’ mRNA deadenylation; Acts as probably catalytic component of the CCR4-NOT core complex, which in the nucleus seems to be a general transcription factor, and in the cytoplasm the major mRNA deadenylase involved in mRNA turnover. In vitro, POP2 has 3’- exoribonuclease activity with a preference for poly(A) RNAs, but also degrades poly(U) and poly(C) RNAs. Is part of a glucose- sensing system involved in growth control in response to glucose availability (433 aa)
Component of the GARP (Golgi-associated retrograde protein) complex, Vps51p-Vps52p-Vps53p-Vps54p, which is required for the recycling of proteins from endosomes to the late Golgi; links the (VFT/GARP) complex to the SNARE Tlg1p; Involved in retrograde transport from early and late endosomes to late Golgi. Links the Golgi-associated retrograde protein (GARP) complex to the t-SNARE TLG1, leading to the fusion between the endosomal vesicles with the late Golgi. May also be indirectly involved in apical bud growth (164 aa)
G1 cyclin involved in regulation of the cell cycle; activates Cdc28p kinase to promote the G1 to S phase transition; late G1 specific expression depends on transcription factor complexes, MBF (Swi6p-Mbp1p) and SBF (Swi6p-Swi4p); Essential for the control of the cell cycle at the G1/S (start) transition. Interacts with the CDC28 protein kinase to form MPF (545 aa)
DNA binding component of the SBF complex (Swi4p-Swi6p), a transcriptional activator that in concert with MBF (Mbp1-Swi6p) regulates late G1-specific transcription of targets including cyclins and genes required for DNA synthesis and repair; Part of a complex involved in cell-cycle-dependent transcription. SWI4 and SWI6 are required for formation of the cell-cycle box factor-DNA complex. The repeated element in the upstream region of HO (5’-CACGAAAA-3’) is called the cell cycle box (CCB) (1093 aa)
Repressor of G1 transcription that binds to SCB binding factor (SBF) at SCB target promoters in early G1; phosphorylation of Whi5p by the CDK, Cln3p/Cdc28p relieves repression and promoter binding by Whi5; periodically expressed in G1; Transcriptional repressor that negatively regulates G1- specific, SBF- and MBF-dependent transcription. Binds via SBF to promoters of G1-specific genes to repress transcription in early G1. During G1, phosphorylated by cyclin-CDK CLN3-CDC28 and progressively hyperphosphorylated by CDK associated with other G1- cyclins, which leads to dissociation of WHI5 [...] (295 aa)
ATPase involved in protein folding and nuclear localization signal (NLS)-directed nuclear transport; member of heat shock protein 70 (HSP70) family; forms a chaperone complex with Ydj1p; localized to the nucleus, cytoplasm, and cell wall; 98% identi /.../th Ssa2p, but subtle differences between the two proteins provide functional specificity with respect to propagation of yeast [URE3] prions and vacuolar-mediated degradations of gluconeogenesis enzymes; May play a role in the transport of polypeptides both across the mitochondrial membranes and into the endoplasmic reticulum. A functio [...] (642 aa)
ATP-dependent DEAD (Asp-Glu-Ala-Asp)-box RNA helicase, required for translation initiation of all yeast mRNAs; mutations in human DEAD-box DBY are a frequent cause of male infertility; ATP-binding RNA helicase involved in translation initiation. Remodels RNA in response to ADP and ATP concentrations by facilitating disruption, but also formation of RNA duplexes. Has weak ATP-dependent affinity for dsRNA, but strong ATP- dependent affinity for ssRNA. Acts as a virus host factor involved in the replication of the MBV and the L-A viruses by promoting the negative-strand RNA synthesis. May [...] (604 aa)
B-type cyclin involved in cell cycle progression; activates Cdc28p to promote the transition from G2 to M phase; accumulates during G2 and M, then targeted via a destruction box motif for ubiquitin-mediated degradation by the proteasome; Essential for the control of the cell cycle at the G2/M (mitosis) transition. Interacts with the CDC2 protein kinase to form MPF. G2/M cyclins accumulate steadily during G2 and are abruptly destroyed at mitosis (491 aa)
