KIN4 protein (Saccharomyces cerevisiae) - STRING interaction network
"KIN4" - Serine/threonine protein kinase that inhibits the mitotic exit network 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

Gene Fusion
KIN4Serine/threonine protein kinase that inhibits the mitotic exit network (MEN) when the spindle position checkpoint is activated; localized asymmetrically to mother cell cortex, spindle pole body and bud neck; This protein is probably a serine/threonine protein kinase (800 aa)    
Predicted Functional Partners:
Adenylate cyclase, required for cAMP production and cAMP-dependent protein kinase signaling; the cAMP pathway controls a variety of cellular processes, including metabolism, cell cycle, stress response, stationary phase, and sporulation; Plays essential roles in regulation of cellular metabolism by catalyzing the synthesis of a second messenger, cAMP (2026 aa)
Component of the GTPase-activating Bfa1p-Bub2p complex involved in multiple cell cycle checkpoint pathways that control exit from mitosis; Part of a checkpoint which monitors spindle integrity and prevents premature exit from mitosis. This cell-cycle arrest depends upon inhibition of the G-protein TEM1 by the BFA1/BUB2 complex (574 aa)
Acetyl-CoA carboxylase, biotin containing enzyme that catalyzes the carboxylation of acetyl-CoA to form malonyl-CoA; required for de novo biosynthesis of long-chain fatty acids; Carries out three functions- biotin carboxyl carrier protein, biotin carboxylase and carboxyltransferase. Involved in the synthesis of very-long-chain fatty acid synthesis which is required to maintain a functional nuclear envelope. Required for acylation and vacuolar membrane association of VAC8 which is necessary to maintain a normal morphology of the vacuole (2233 aa)
Mitochondrial acetyl-coenzyme A carboxylase, catalyzes the production of malonyl-CoA in mitochondrial fatty acid biosynthesis; Catalyzes the rate-limiting reaction in the mitochondrial fatty acid synthesis (FAS) type II pathway. Responsible for the production of the mitochondrial malonyl-CoA, used for the biosynthesis of the cofactor lipoic acid. This protein carries three functions- biotin carboxyl carrier protein, biotin carboxylase, and carboxyltransferase (2123 aa)
Protein similar to GDP/GTP exchange factors; without detectable GEF activity; required for asymmetric localization of Bfa1p at daughter-directed spindle pole bodies and for mitotic exit at low temperatures; GDP-GTP exchange factor for TEM1, a Ras-like protein, component of the mitotic exit network (MEN). Activation of TEM1 by LTE1 in the bud ultimately leads to activation of CDC15 followed by the release of CDC14 from the nucleolus, which then inactivates cyclin-dependent kinases (CDKs) activity by several mechanism. Required for TEM1 localization to the bud cortex during mitotic exit. [...] (1435 aa)
Mitotic exit network regulator, forms GTPase-activating Bfa1p-Bub2p complex that binds Tem1p and spindle pole bodies, blocks cell cycle progression before anaphase in response to spindle and kinetochore damage; Part of a checkpoint which monitors spindle integrity and prevents premature exit from mitosis. This cell-cycle arrest depends upon inhibition of the GTP-binding protein TEM1 by the BFA1/BUB2 complex (306 aa)
GTP-binding protein of the ras superfamily involved in termination of M-phase; controls actomyosin and septin dynamics during cytokinesis; GTP-binding protein involved in termination of M phase. May play a role in triggering the degradation of G2 cyclin to inactivate M-phase promoting factor at the termination of mitosis. Acts upstream of CDC15 kinase and may be required to activate the CDC15 protein kinase pathway (245 aa)
Component of the cytoplasmic Tub4p (gamma-tubulin) complex, binds spindle pole bodies and links them to microtubules; has roles in astral microtubule formation and stabilization; Spindle pole body component that acts as the gamma- tubulin complex-binding protein of the SPB outer plaque. Anchors cytoplasmic microtubules at the at the half bridge of the spindle pole body (SPB) and accordingly functions in nuclear position and spindle orientation, including anaphase spindle migration into the bud. Recruits KIN4 kinase to both SPBs when cytoplasmic microtubules are defective. Links cytopla [...] (622 aa)
Type 2C protein phosphatase (PP2C); dephosphorylates Hog1p (see also Ptc2p) to limit maximal kinase activity induced by osmotic stress; dephosphorylates T169 phosphorylated Cdc28p (see also Ptc2p); role in DNA damage checkpoint inactivation; Responsible, together with PTC2, for the dephosphorylation of the cyclin-dependent protein kinase CDC28 (468 aa)
B-type regulatory subunit of protein phosphatase 2A (PP2A); Rts1p and Cdc55p are alternative regulatory subunits for PP2A; PP2A-Rts1p protects cohesin when recruited by Sgo1p to the pericentromere; highly enriched at centromeres in absence of Cdc55p /.../log of the mammalian B’ subunit of PP2A; The B regulatory subunit might modulate substrate selectivity and catalytic activity, and also might direct the localization of the catalytic enzyme to a particular subcellular compartment (757 aa)
