PAC1 protein (Saccharomyces cerevisiae) - STRING interaction network
"PAC1" - Protein involved in nuclear migration, part of the dynein/dynactin pathway 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

PAC1Protein involved in nuclear migration, part of the dynein/dynactin pathway; targets dynein to microtubule tips, which is necessary for sliding of microtubules along bud cortex; synthetic lethal with bni1; homolog of human LIS1; Positively regulates the activity of the minus-end directed microtubule motor protein dynein. Plays a central role in positioning the mitotic spindle at the bud neck during cell division. Targets cytoplasmic dynein to microtubule plus ends, thereby promoting dynein-mediated microtubule sliding along the bud cortex and consequently the movement of the mitotic spi [...] (494 aa)    
Predicted Functional Partners:
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)
Large subunit of the dynactin complex, which is involved in partitioning the mitotic spindle between mother and daughter cells; putative ortholog of mammalian p150(glued); Motor-binding component of the dynactin complex which assists cytoplasmic dynein by increasing its processivity and by regulation of its cargo binding (By similarity). The dynactin complex is required for the spindle translocation late in anaphase and is involved in a cell wall synthesis checkpoint (868 aa)
Cholinephosphotransferase, required for phosphatidylcholine biosynthesis and for inositol-dependent regulation of EPT1 transcription; Catalyzes the final step in the CDP-choline route leading to phosphatidylcholin (PC). Preferentially uses CDP- monomethylethanolamine as aminoalcohol substrate. Shows highest activity toward di- and mono-unsaturated diacylglycerol species as lipid substrates. The CDP-choline pathway only contributes to net PC synthesis if exogenous choline is present. In its absence, this pathway recycles choline from PC turnover and may contribute to maintaining the pro [...] (393 aa)
Multifunctional triacylglycerol lipase, steryl ester hydrolase, and Ca2+-independent phospholipase A2; catalyzes acyl-CoA dependent acylation of LPA to PA; required with Tgl3p for timely bud formation; phosphorylated and activated by Cdc28p; Releases specific fatty acids from neutral lipid triacylglycerols (TAG) thereby supplying fatty acids to a general acylation process. May have a specific role in sporulation (910 aa)
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)
Homolog of nuclear distribution factor NudE, NUDEL; interacts with Pac1p and regulates dynein targeting to microtubule plus ends; Required for nuclear migration to the bud neck during cell division. Targets cytoplasmic dynein to microtubule plus ends thereby promoting dynein-mediated microtubule sliding along the bud cortex and consequently the movement of the mitotic spindle to the bud neck (189 aa)
Cytoplasmic light chain dynein, microtubule motor protein; proposed to be involved in the assembly of the nuclear pore complex; Acts as one of several non-catalytic accessory components of the cytoplasmic dynein complex that are thought to be involved in linking dynein to cargos and to adapter proteins that regulate dynein function. Cytoplasmic dynein 1 acts as a motor for the intracellular retrograde motility of vesicles and organelles along microtubules. May play a role in changing or maintaining the spatial distribution of cytoskeletal structures (By similarity) (92 aa)
Protein required for nuclear migration, localizes to the mother cell cortex and the bud tip; may mediate interactions of dynein and cytoplasmic microtubules with the cell cortex; Controls nuclear migration. NUM1 specifically controls the interaction of the bud neck cytoskeleton with the pre- divisional G2 nucleus. Functions in dynein-anchoring. During late anaphase forms dynein-interacting cortical microtubule capture sites at both cellular poles. This leads to dynein-dependent sliding of the microtubules in the bud (2748 aa)
Broad-specificity lysophospholipid acyltransferase, part of MBOAT family of membrane-bound O-acyltransferases; key component of Lands cycle; may have role in fatty acid exchange at sn-2 position of mature glycerophospholipids; Membrane-bound O-acyltransferase that mediates the incorporation of unsaturated acyl chains into the sn-2 position of phospholipids. Preferentially acylates lysophosphocholine, but also lysophosphoethanolamine and lysophosphatidylglycerol (619 aa)
SET domain protein of unknown function; deletion heterozygote is sensitive to compounds that target ergosterol biosynthesis, may be involved in compound availability; Involved in resistance to compounds that target ergosterol biosynthesis, including fenpropimorph, dyclonine, and alverine citrate. Since a deletion in the absence of these compounds does not have an effect on growth, is more likely to be involved in compound availability (373 aa)
