Summary: Enables diacylglycerol-dependent serine/threonine kinase activity. Involved in several processes, including cellular bud neck septin ring organization; pexophagy; and positive regulation of cytoplasmic mRNA processing body assembly. Located in several cellular components, including cytoplasmic stress granule; cytoskeleton; and site of polarized growth. Human ortholog(s) of this gene implicated in several diseases, including autoimmune lymphoproliferative syndrome type 3; carcinoma (multiple); high grade glioma (multiple); spinocerebellar ataxia type 14; and steatotic liver disease. Orthologous to several human genes including PRKCA (protein kinase C alpha); PRKCB (protein kinase C beta); and PRKCD (protein kinase C delta). [provided by Alliance of Genome Resources, Jul 2025]

Stress granules sense metabolic stress at the plasma membrane and potentiate recovery by storing active Pkc1.
Title: Stress granules sense metabolic stress at the plasma membrane and potentiate recovery by storing active Pkc1.
Pkc1 triggers dispersal of Ste5 from mating projections upon mechanically induced stress and during cell-cell fusion, leading to inhibition of the MAPK Fus3.
Title: Mechanical stress impairs pheromone signaling via Pkc1-mediated regulation of the MAPK scaffold Ste5.
Pkc1 in cooperation with calcineurin mediates cell survival under compressive mechanical stress.
Title: Protein kinase C and calcineurin cooperatively mediate cell survival under compressive mechanical stress.
The Pkc1-mediated degradation of Pah1 was attenuated in the cho1Delta mutant, which is deficient in PS synthase, supporting the notion that the phospholipid regulates Pkc1 activity in vivo.
Title: Phosphorylation of lipid metabolic enzymes by yeast protein kinase C requires phosphatidylserine and diacylglycerol.
Constitutively active Pkc1 can drive cells through a mitotic checkpoint arrest, which suggests that Pkc1-dependent activation of PP2A(Cdc55) plays a critical role in checkpoint signaling.
Title: Protein Kinase C Controls Binding of Igo/ENSA Proteins to Protein Phosphatase 2A in Budding Yeast.
Pkc1 also enhances H3T45 phosphorylation and this modification is required for H3K56 acetylation.
Title: Protein kinase C coordinates histone H3 phosphorylation and acetylation.
Authors propose that Rho1 and Pkc1 coordinate septin ring assembly with membrane and cell wall remodeling partly by controlling Syp1 residence at the bud neck.
Title: Rho1- and Pkc1-dependent phosphorylation of the F-BAR protein Syp1 contributes to septin ring assembly.
The Mih1 is negatively regulated by Pkc1-mediated phosphorylation, which excludes it from the nucleus under certain conditions.
Title: Mih1/Cdc25 is negatively regulated by Pkc1 in Saccharomyces cerevisiae.
This study connects the Pkc1 protein to the maintenance of genome integrity in response to genotoxic stresses.
Title: Protein kinase C controls activation of the DNA integrity checkpoint.
activation of PKC-MAPK signaling by interruption of inositol sphingolipid synthesis leads to increased Sir2p-dependent silencing and is dependent upon the de novo and salvage pathways for NAD(+) synthesis but is not correlated with cellular NAD(+) levels
Title: Activation of protein kinase C-mitogen-activated protein kinase signaling in response to inositol starvation triggers Sir2p-dependent telomeric silencing in yeast.
