Protein: FIGNL1-interacting regulator of recombination and mitosis (Q9NSG2)
Organism: Homo sapiens (Human)
Function: Regulates PLK1 kinase activity at kinetochores and promotes faithful chromosome segregation in prometaphase by bridging kinase and phosphatase activities. Phosphorylation of FIRRM by PLK1 negatively regulates its interaction with the phosphatase, PPP1CC, thus creating a negative feedback loop for maintaining proper PLK1 kinase activity during mitosis. In complex with FIGL1 may regulate homologous recombination
Subcellular location: Chromosome, centromere, kinetochore. Nucleus. Chromosome, centromere. Midbody. Cytoplasm, cytoskeleton, spindle. Note=Exhibits cell-cycle-dependent distribution during mitosis. Detected in the nucleus in interphase. Colocalizes with PLK1 to the centromeres in a nearby prometaphase cells. Relocates to the central spindle in anaphase and to the midbody in telophase cells
