Acts as a suppressor component of the dual wtf meiotic drive system, and can suppress but not confer meiotic drive by compatible poisons (By similarity). Wtf meiotic drive systems promote unequal transmission of alleles from the parental zygote to progeny spores by encoding a poison and an antidote from the same locus; the poison is trans-acting and forms toxic aggregates in all spores within an ascus, wherease the antidote is spore-specific and targets aggregates for degradation by the vacuole (By similarity). Meiotic drive by wtf systems therefore lead to poisoning of all progeny that do not inherit the dual poison/antidote allele, or express a compatible antidote (By similarity). Homomer (By similarity). Interacts with other proteins that exhibit high sequence similarity (By similarity). Belongs to the WTF family.
