SIC1

SDB25, cyclin-dependent protein serine/threonine kinase inhibiting protein SIC1, L000001886, L000001822, YLR079W
Cyclin-dependent kinase inhibitor (CKI); inhibitor of Cdc28-Clb kinase complexes that controls G1/S phase transition, preventing premature S phase and ensuring genomic integrity; phosphorylated by Clb5/6-Cdk1 and Cln1/2-Cdk1 kinase which regulate timing of Sic1p degradation; phosphorylation targets Sic1p for SCF(CDC4)-dependent turnover; functional homolog of mammalian Kip1

RS1, L000001777, YER173W
Checkpoint protein; involved in the activation of the DNA damage and meiotic pachytene checkpoints; subunit of a clamp loader that loads Rad17p-Mec3p-Ddc1p onto DNA; homolog of human and S. pombe Rad17 protein

Synthetic Growth Defect

A genetic interaction is inferred when mutations in separate genes, each of which alone causes a minimal phenotype, result in a significant growth defect under a given condition when combined in the same cell.

The yeast CDK inhibitor Sic1 prevents genomic instability by promoting replication origin licensing in late G(1).

Lengronne A, Schwob E

G(1) cell cycle regulators are often mutated in cancer, but how this causes genomic instability is unclear. Here we show that yeast lacking the CDK inhibitor Sic1 initiate DNA replication from fewer origins, have an extended S phase, and inefficiently separate sister chromatids during anaphase. This leads to double-strand breaks (DSBs) in a fraction of sic1 cells as evidenced by ... [more]
