CC -!- FUNCTION: Promotes unequal transmission of alleles from the parental
CC zygote to progeny spores by acting as poison/antidote system where the
CC poison and antidote proteins are produced from the same locus; the
CC poison component is trans-acting and targets all spores within an ascus
CC whereas the antidote component is spore-specific, leading to poisoning
CC of all progeny that do not inherit the allele.
CC {ECO:0000269|PubMed:28631612, ECO:0000269|PubMed:32790622,
CC ECO:0000269|PubMed:33108274}.
CC -!- FUNCTION: [Isoform 1]: Localizes isoform 2 to the vacuole thereby
CC facilitating its degradation. {ECO:0000269|PubMed:28631612,
CC ECO:0000269|PubMed:32790622, ECO:0000269|PubMed:33108274}.
CC -!- FUNCTION: [Isoform 2]: Forms toxic aggregates that disrupt spore
CC maturation. {ECO:0000269|PubMed:28631612, ECO:0000269|PubMed:32790622,
CC ECO:0000269|PubMed:33108274}.
CC -!- SUBUNIT: Homomer (PubMed:33108274). Forms protein aggregates
CC (PubMed:33108274). The two isoforms can interact with each other and
CC with themselves (PubMed:33108274). High sequence similarity is required
CC for their interaction (By similarity). {ECO:0000250|UniProtKB:O74420,
CC ECO:0000269|PubMed:33108274}.
CC -!- SUBCELLULAR LOCATION: [Isoform 1]: Spore membrane {ECO:0000255,

CC {ECO:0000255}. Note=Localizes in trans to all spores within an ascus.
CC Localization to the spore vacuole is dependent on isoform 1.
