Component of a FANCM-MHF complex that promotes gene conversion at blocked replication forks, probably by reversal of the stalled fork (Probable). FANCM-MHF promotes non-crossover recombination (PubMed:22723423). The MHF histone-fold complex is a heterotetramer of 2 mhf1-mhf2 heterodimers (By similarity). Component of the inner kinetochore constitutive centromere-associated network (CCAN) (also known as central kinetochore Sim4 complex in fission yeast), which is composed of at least cnl2, cnp3, cnp20, fta1, fta2, fta3, fta4, fta6, fta7, mal2, mhf1, mhf2, mis6, mis15, mis17, sim4 and wip1 (By similarity). Belongs to the CENP-X/MHF2 family. An article showing that FANCM-MHF promotes gene conversion at blocked replication forks by fork reversal was withdrawn due to genotype mislabeling of strains. Following strain regeneration, although many phenotypes were not reproducible, the central observations of the publication were confirmed.
