Summary: Enables phosphatidylinositol-4,5-bisphosphate phospholipase C activity. Involved in several processes, including inositol phosphate biosynthetic process; protein localization to kinetochore; and signal transduction involved in filamentous growth. Located in kinetochore. Human ortholog(s) of this gene implicated in several diseases, including autoinflammation, antibody deficiency, and immune dysregulation syndrome; carcinoma (multiple); developmental and epileptic encephalopathy 12; familial cold autoinflammatory syndrome 3; and myelodysplastic syndrome. Orthologous to several human genes including PLCD3 (phospholipase C delta 3) and PLCD4 (phospholipase C delta 4). [provided by Alliance of Genome Resources, Jul 2025]

What's a GeneRIF?

Plc1p and InsPs are required for normal acetyl-CoA homeostasis, which, in turn, regulates global histone acetylation.
Title: Yeast phospholipase C is required for normal acetyl-CoA homeostasis and global histone acetylation.
The results show that MHO1 is a novel synthetic lethal interactor with PLC1, and that both gene products are required for proliferation (MHO1).
Title: MHO1, an evolutionarily conserved gene, is synthetic lethal with PLC1; Mho1p has a role in invasive growth.
Plc1p affects transcription of Mcm1p-dependent genes,probably by a mechanism involving regulation of chromatin remodeling complexes.
Title: Role of Plc1p in regulation of Mcm1p-dependent genes.
Mutations in PLC1 and components of the RSC complex exhibit strong genetic interactions and display synthetic growth defect, altered nuclear morphology, and higher frequency of minichromosome loss.
Title: Plc1p is required for proper chromatin structure and activity of the kinetochore in Saccharomyces cerevisiae by facilitating recruitment of the RSC complex.
Genes regulated by Plc1p do not correlate with gene sets regulated by Swi/Snf or RSC chromatin remodeling complexes but show correlation with genes controlled by Msn2p.
Title: Saccharomyces cerevisiae phospholipase C regulates transcription of Msn2p-dependent stress-responsive genes.
The results thus provide evidence that Plc1p and inositol polyphosphates affect derepression of Sko1p-Ssn6p-Tup1p-controlled genes by a mechanism that involves recruitment of the SAGA complex and TATA-binding protein.
Title: Plc1p is required for SAGA recruitment and derepression of Sko1p-regulated genes.
Data suggest that expression of FLR1 can be regulated by phospholipase C, a component of a signal transduction pathway, and by Mediator, a general transcription factor.
Title: Expression of FLR1 transporter requires phospholipase C and is repressed by Mediator.
Plc1p, Arg82p, and Kcs1p are enzymes involved in inositol pyrophosphate synthesis and are essential for phosphate regulation and polyphosphate accumulation
Title: Plc1p, Arg82p, and Kcs1p, enzymes involved in inositol pyrophosphate synthesis, are essential for phosphate regulation and polyphosphate accumulation in Saccharomyces cerevisiae.
