STRING protein interaction network
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

psl1PHO85 cyclin-like protein psl1; Cyclin partner of the cyclin-dependent kinase (CDK) pef1 (PHO85 homolog) (243 aa)    
Predicted Functional Partners:
Pho85/PhoA-like cyclin-dependent kinase Pef1; Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. CDC2/CDKX subfamily
G1/S-specific cyclin pas1; Essential for the control of the cell cycle at the G1/S (start) transition. Interacts with the pef1 protein kinase. The pef1/pas1 complex activates the res2/cdc10 complex
Cyclin-dependent kinase 1; Plays a key role in the control of the eukaryotic cell cycle. It is required for entry into S-phase and mitosis. When complexed with cig2, plays a role in G1-S phase transition. When activated and complexed with the cyclin cdc13, it leads to the onset of mitosis. p34 is a component of the kinase complex that phosphorylates the repetitive C-terminus of RNA polymerase II. Involved in cell cycle arrest induced by defective RNA splicing. Required for phosphorylation of dis1 to ensure accurate chromosome segregation and for the DNA damage checkpoint
Serine/threonine-protein kinase crk1; Protein kinase essential for cell proliferation, where it is required for completion of cytokinesis. Phosphorylates the C-terminal repeat domain (CTD) of RNA polymerase II; Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. CDC2/CDKX subfamily
Uncharacterized cyclin-L1-like protein C1296.05c; Cyclin L family cyclin
Glycerophosphodiester phosphodiesterase gde1; Glycerophosphocholine glycerophosphodiesterase responsible for the hydrolysis of intracellular glycerophosphocholine into glycerol-phosphate and choline
CTD kinase subunit alpha; Catalytic subunit of the CTDK-I complex, which hyperphosphorylates the C-terminal heptapeptide repeat domain (CTD) of the largest RNA polymerase II subunit. Involved in RNA polymerase II transcriptional elongation and pre-mRNA 3'-end processing (By similarity). Together with ctk2/lsc1, required for the regulation of cytokinesis by phosphorylating 'Ser-2' residues found in the heptad repeats of the CTD. Required for nuclear localization of ctk2/lsc1. Positively regulates the septation initiation network (SIN) and promotes successful completion of cytokinesis in [...]
Probable cyclin-dependent kinase 9; Component of the positive transcription elongation factor b (P-TEFb) which consists of cdk9 and pch1, and which phosphorylates the C-terminal domain (CTD) of RNA polymerase II and spt5
G2/mitotic-specific cyclin cig2; Essential for the control of the cell cycle at the G2/M and G1/S (mitosis) transition. Interacts with the cdc2 protein kinase to form MPF. Interaction with res2 promotes the phosphorylation of res1 and inhibits MBF-dependent gene transcription. Forms an autoregulating feedback-inhibition loop with MBF which is important for normal regulation of the cell cycle. G2/M cyclins accumulate steadily during G2 and are abruptly destroyed at mitosis. Negatively regulates conjugation via interacting with cell cycle 'start' genes. Degraded by skp1, pop1 and pop2 in [...]
Cyclin pch1; Essential for progression through the whole cell cycle; Belongs to the cyclin family. Cyclin C subfamily
