Summary: Enables protein kinase activity. Involved in negative regulation of DNA replication origin binding activity; protein phosphorylation; and regulation of meiotic nuclear division. Located in nucleus. Human ortholog(s) of this gene implicated in endocrine-cerebro-osteodysplasia syndrome; juvenile myoclonic epilepsy 10; and retinitis pigmentosa 62. Orthologous to human CILK1 (ciliogenesis associated kinase 1) and MAK (male germ cell associated kinase). [provided by Alliance of Genome Resources, Apr 2022]

What's a GeneRIF?

identify the protein kinase Ime2 to bring about Rim4 clearance via phosphorylation of Rim4's intrinsically disordered region
Title: Phosphorylation-Mediated Clearance of Amyloid-like Assemblies in Meiosis.
Here we show that Ime2 activity is required to induce the translation of SSP2 mRNA at anaphase II
Title: Autophosphorylation of the Smk1 MAPK is spatially and temporally regulated by Ssp2 during meiotic development in yeast.
Positive auto-regulation of Ime2 produces a bistable system with a normal meiotic state and a more efficient meiotic state.
Title: Dynamic modeling of yeast meiotic initiation.
Ime2 does not directly catalyze Sic1 phosphorylation to target it for destabilization as Cln1,-2/Cdk1 do during the cell cycle
Title: Yeast IME2 functions early in meiosis upstream of cell cycle-regulated SBF and MBF targets.
The ectope expression of Ime2 has deterious on cell cycle regulation, toxocity and the response of the DNA damage checkpoint.
Title: Ectopic expression of human Cdk2 and its yeast homolog, Ime2, is deleterious to Saccharomyces cerevisiae.
Epistasis analysis suggests that Ime1 and Ime2 act in the same order in pseudohyphal growth as in meiosis.
Title: Ime1 and Ime2 are required for pseudohyphal growth of Saccharomyces cerevisiae on nonfermentable carbon sources.
Data show that the Sum1 repressor can be removed from middle promoters in meiotic cells independent of Ndt80 expression, and that this process requires the phosphorylation of Sum1 by Ime2.
Title: The Ime2 protein kinase enhances the disassociation of the Sum1 repressor from middle meiotic promoters.
Ime2 is a key activator of Smk1 signaling.
Title: The Ras/cAMP pathway and the CDK-like kinase Ime2 regulate the MAPK Smk1 and spore morphogenesis in Saccharomyces cerevisiae.
Results show that human Cdk2 is a functional homolog for most of Ime2 functions.
Title: Human Cdk2 is a functional homolog of budding yeast Ime2, the meiosis-specific Cdk-like kinase.
The glucose sensors had only a minor role in regulating transcript levels of the two key regulators of meiotic initiation, the Ime1p transcription factor and the Ime2p kinase, but a major role in regulating Ime2p stability.
Title: Glucose induction pathway regulates meiosis in Saccharomyces cerevisiae in part by controlling turnover of Ime2p meiotic kinase.
