CC   -!- FUNCTION: Acts as a suppressor component of the dual wtf meiotic drive
CC       system, and can suppress but not confer meiotic drive by compatible
CC       poisons (PubMed:32032353). Wtf meiotic drive systems promote unequal
CC       transmission of alleles from the parental zygote to progeny spores by
CC       encoding a poison and an antidote from the same locus; the poison is
CC       trans-acting and forms toxic aggregates in all spores within an ascus,
CC       wherease the antidote is spore-specific and targets aggregates for
CC       degradation by the vacuole (By similarity). Meiotic drive by wtf
CC       systems therefore lead to poisoning of all progeny that do not inherit
CC       the dual poison/antidote allele, or express a compatible antidote (By
CC       similarity). {ECO:0000250|UniProtKB:A0A218N034,
CC       ECO:0000250|UniProtKB:A0A482ATU4, ECO:0000269|PubMed:32032353}.
CC   -!- SUBUNIT: Homomer (By similarity). Interacts with other proteins that
CC       exhibit high sequence similarity (By similarity).
