STRINGSTRING
PCL1 protein (Saccharomyces cerevisiae) - STRING interaction network
"PCL1" - Cyclin, interacts with cyclin-dependent kinase Pho85p in Saccharomyces cerevisiae
Nodes:
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:
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
Others
textmining
co-expression
protein homology

PCL1Cyclin, interacts with cyclin-dependent kinase Pho85p; member of the Pcl1,2-like subfamily, involved in the regulation of polarized growth and morphogenesis and progression through the cell cycle; localizes to sites of polarized cell growth; G1/S-specific cyclin partner of the cyclin-dependent kinase (CDK) PHO85. Essential for the control of the cell cycle at the G1/S (start) transition. The PCL1-PHO85 cyclin-CDK holoenzyme is involved in phosphorylation of the CDK inhibitor (CKI) SIC1, which is required for its ubiquitination and degradation, releasing repression of b-type cyclins and [...] (279 aa)    
Predicted Functional Partners:
PHO85
Cyclin-dependent kinase, with ten cyclin partners; involved in regulating the cellular response to nutrient levels and environmental conditions and progression through the cell cycle; Cyclin-dependent protein kinase (CDK) catalytic subunit that regulates multiple cell cycle and metabolic processes in response to nutrient availability. Associates with different cyclins, that control kinase activity, substrate specificity and subcellular location of the kinase. Favorable growth conditions always result in activated cyclin-CDK complexes. Regulates metabolic processes when associated with [...] (305 aa)
       
  0.996
CLN2
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)
     
  0.980
CDC28
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)
       
  0.969
YOX1
Homeodomain-containing transcriptional repressor, binds to Mcm1p and to early cell cycle boxes (ECBs) in the promoters of cell cycle-regulated genes expressed in M/G1 phase; expression is cell cycle-regulated; potential Cdc28p substrate; Transcriptional repressor required to restrict transcription of ECB-dependent genes to the G1/M phase by repressing their transcription during the interval from late G1 to M phases. Genes that contain a ECB (early cell box) element in their transcription regulatory region are transcribed only during G1/M phases. In vitro, is capable of binding to the D [...] (385 aa)
     
   
  0.937
SWI4
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)

PCL2
Cyclin, interacts with cyclin-dependent kinase Pho85p; member of the Pcl1,2-like subfamily, involved in the regulation of polarized growth and morphogenesis and progression through the cell cycle; localizes to sites of polarized cell growth; G1/S-specific cyclin partner of the cyclin-dependent kinase (CDK) PHO85. Essential for the control of the cell cycle at the G1/S (start) transition. Together with cyclin PCL1, positively controls degradation of sphingoid long chain base kinase LCB4. The PCL2-PHO85 cyclin-CDK holoenzyme phosphorylates LCB4, which is required for its ubiquitination a [...] (308 aa)

CLG1
Cyclin-like protein that interacts with Pho85p; has sequence similarity to G1 cyclins PCL1 and PCL2; Cyclin partner of the cyclin-dependent kinase (CDK) PHO85. Has a role in cell integrity and polarized cell growth together with the other PCL1/PCL2 cyclin family members (452 aa)
         
  0.915
PCL8
Cyclin, interacts with Pho85p cyclin-dependent kinase (Cdk) to phosphorylate and regulate glycogen synthase, also activates Pho85p for Glc8p phosphorylation; Cyclin partner of the cyclin-dependent kinase (CDK) PHO85. Together with cyclin PCL10, negatively controls glycogen accumulation under favorable growth conditions. Involved in phosphorylation and negative regulation of glycogen synthase GSY2. Also has minor GLC8 kinase activity (492 aa)

PHO80
Cyclin, interacts with cyclin-dependent kinase Pho85p; regulates the response to nutrient levels and environmental conditions, including the response to phosphate limitation and stress-dependent calcium signaling; Cyclin partner of the cyclin-dependent kinase (CDK) PHO85. Negatively regulates the expression of phosphate- starvation-responsive genes under phosphate-rich conditions. The PHO80-PHO85 cyclin-CDK holoenzyme phosphorylates and inactivates the transcription factor PHO4, by preventing its association with the transcription factor PHO2 and the nuclear import receptor PSE1, and b [...] (293 aa)

CLB1
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 (471 aa)
