Transcription factor that regulates the expression of the CLB2 cluster of genes during the G2/M phase of the mitotic cell cycle (PubMed:10959837, PubMed:10894548, PubMed:10894549, PubMed:11562353, PubMed:12702877, PubMed:17283050, PubMed:24504085). The CLB2 cluster of genes includes mitotic regulators such as CLB1, CLB2, CDC5 and CDC20 as well as SWI5 and ACE2, transcription factors required for the subsequent temporal wave of cell cycle regulated gene expression in the M/G1 phase interval (PubMed:10959837, PubMed:10894548, PubMed:11562353). Involved in HMRa silencing (PubMed:10747051). FKH1 and FKH2 associate with the coding regions of active genes and influence, in opposing ways, transcriptional elongation and termination, and coordinate early transcription elongation and pre-mRNA processing (PubMed:12702877). Both FKH1 and FKH2 play a role as regulators of lifespan in collaboration with the anaphase-promoting complex (APC), likely through combined regulation of stress response, genomic stability, and cell cycle regulation (PubMed:22438832). FKH1 and FKH2 function also in controlling yeast cell morphology by preventing preudohyphal growth (PubMed:10747051, PubMed:10894548). Acts as a rate-limiting replication origin activator via its interactin with the origin recognition complex (ORC) (PubMed:22265405, PubMed:26728715). Plays a transcription-independent role in recombination donor preference during mating-type switching through binding to the recombination enhancer (RE), a 700-bp cis-acting element that controls recombination along the left arm of chromosome III (PubMed:12183363, PubMed:16809780, PubMed:22496671, PubMed:27257873). Interacts (via FHA domain) with ECM30, GLN3, URE2, MPH1 AND FDO1 (PubMed:27257873). Interacts with the origin recognition complex (ORC) composed of ORC1 to ORC6 (PubMed:22265405). Relocalizes to the cytosol in response to hypoxia. The phosphothreonine-binding FHA domain is required for the interaction with MPH1 and controlling recombination donor preference during mating-type switching. Causes only a modest decline in CLB2 cluster genes expression, but this expression is abolished when both FKH1 and FKH2 are deleted (PubMed:10959837). Leads to a defect in silencing HMRa (PubMed:10747051). Causes a form of yeast pseudohyphal growth, when FKH2 is also deleted (PubMed:10747051). Affects cell-cycle progression and CLB2 mRNA expression (PubMed:10747051). Leads to defect in pre-mRNA 3' end formation during transcription of targeted genes (PubMed:12702877). Present with 1720 molecules/cell in log phase SD medium.
