KAR9 protein (Saccharomyces cerevisiae) - STRING interaction network
"KAR9" - Karyogamy protein required for correct positioning of the mitotic spindle and for orienting cytoplasmic microtubules, localizes at the shmoo tip in mating cells and at the tip of the growing bud in small-budded cells through anaphase 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

KAR9Karyogamy protein required for correct positioning of the mitotic spindle and for orienting cytoplasmic microtubules, localizes at the shmoo tip in mating cells and at the tip of the growing bud in small-budded cells through anaphase; Involved in karyogamy. Component of a cortical adaptor complex that orients cytoplasmic microtubules. It may be involved in anchoring cytoplasmic microtubules to the cell cortex (644 aa)    
Predicted Functional Partners:
Microtubule-associated protein, component of the interface between microtubules and kinetochore, involved in sister chromatid separation; essential in polyploid cells but not in haploid or diploid cells; ortholog of mammalian CLIP-170; Required for nuclear fusion, chromosome disjunction, and nuclear segregation during mitosis. Probably required for the formation or stabilization of microtubules during mitosis and for spindle pole body fusion during conjugation (440 aa)
Microtubule-binding protein that together with Kar9p makes up the cortical microtubule capture site and delays the exit from mitosis when the spindle is oriented abnormally; Binds microtubules (344 aa)
Microtubule-associated protein (MAP) of the XMAP215/Dis1 family; regulates microtubule dynamics during spindle orientation and metaphase chromosome alignment; interacts with spindle pole body component Spc72p; May play a role in the attachment, organization, and/or dynamics of microtubule ends at the spindle pole body (888 aa)
RING finger protein involved in proteolytic control of sumoylated substrates; interacts with SUMO (Smt3p); member of the SWI/SNF family of DNA-dependent ATPases; plays a role in antagonizing silencing during mating-type switching; ATP-dependent helicase involved mating type switching and in silencing interference through its interaction with the silencing regulator SIR4. Cooperates with UBC4 and UBC5 to mediate ubiquitination of SUMO conjugates (1619 aa)
Subunit of the Slx5-Slx8 SUMO-targeted ubiquitin ligase (STUbL) complex; stimulated by prior attachment of SUMO to the substrate; contains a C-terminal RING domain; Mediates ubiquitination and subsequent desumoylation/degradation of sumoylated proteins and proteins containing SUMO-like domains. Promotes UBC4-dependent ubiquitination that mediates the proteolytic down-regulation of sumoylated proteins. Involved in the stimulation of ubiquitin conjugating enzymes, including UBC1, UBC4, UBC5 and UBC13-MMS2. Acts as a critical suppressor of gross chromosomal rearrangements (GCRs) during no [...] (274 aa)
Kinesin-related motor protein involved in mitotic spindle positioning, stabilizes microtubules by targeting Bik1p to the plus end; Kip2p levels are controlled during the cell cycle; Required for assembly of the mitotic spindle (706 aa)
Kinesin motor protein involved in mitotic spindle assembly and chromosome segregation; Required for assembly of the mitotic spindle. Interacts with spindle microtubules to produce an outwardly directed force acting upon the poles. Following spindle assembly, CIN8 and KIP1 apparently act to oppose a force that draws separated poles back together. This force seems to be mediated by KAR3 (1000 aa)
Cytoplasmic heavy chain dynein, microtubule motor protein, required for anaphase spindle elongation; involved in spindle assembly, chromosome movement, and spindle orientation during cell division, targeted to microtubule tips by Pac1p; Cytoplasmic dynein acts as a motor for the intracellular retrograde motility of vesicles and organelles along microtubules. Dynein has ATPase activity; the force-producing power stroke is thought to occur on release of ADP. Required to maintain uniform nuclear distribution in hyphae. May play an important role in the proper orientation of the mitotic sp [...] (4092 aa)
One of two type V myosin motors (along with MYO4) involved in actin-based transport of cargos; required for the polarized delivery of secretory vesicles, the vacuole, late Golgi elements, peroxisomes, and the mitotic spindle; Myosin heavy chain that is required for the cell cycle- regulated transport of various organelles and proteins for their segregation. Functions by binding with its tail domain to receptor proteins on organelles and exerting force with its N-terminal motor domain against actin filaments, thereby transporting its cargo along polarized actin cables. Essential for the [...] (1574 aa)
Kinetochore-associated protein required for normal segregation of chromosomes in meiosis and mitosis; component of the FEAR regulatory network, which promotes Cdc14p release from the nucleolus during anaphase; potential Cdc28p substrate; Has a role in spindle assembly and stability. Required to ensure a timely exit form mitosis. Essential to maintain pre- anaphase spindle polarity. Associates to the plus ends of the microtubules at the kinetochore and spindle midzone. A component of the FEAR (CDC14 Early Anaphase Release) network which promotes CDC14 release from the nucleolus during e [...] (821 aa)
