Protein: S-phase delaying protein 1 (Protein p14) (Q10585)
Organism: Schizosaccharomyces pombe (strain 972 / ATCC 24843) (Fission yeast)
Function: Regulates the ribonucleotide reductase activity through its mediation of the nuclear localization of suc22, the small subunit of the ribonucleotide reductase. Delays the progression of the G1-S phase transition, thereby ensuring the G1 phase is complete. Interacts with both p34 and the p34-p56 complex, although no direct inhibitory effect on the bound proteins has been demonstrated. The action of p14 may happen coincidentally with the cdc10 function or may happen downstream of this.
Subcellular location: Cytoplasm. Nucleus.
InterPro domains:
- IPR013900: Ribonucleotide reductase inhibitor (family) [9-91]
