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:32032353}.
CC -!- FUNCTION: [Isoform 1]: Localizes isoform 2 to the vacuole thereby
CC facilitating its degradation (By similarity). In addition to
CC suppressing isoform 2, also suppresses S.pombe strain 972 wtf13 isoform
CC 2 (PubMed:32032353). {ECO:0000250|UniProtKB:A0A218N034,
CC ECO:0000269|PubMed:32032353}.
CC -!- FUNCTION: [Isoform 2]: Forms toxic aggregates that disrupt spore
CC maturation. {ECO:0000250|UniProtKB:A0A218N034}.
CC -!- SUBUNIT: Homomer (By similarity). Forms protein aggregates (By
CC similarity). The two isoforms can interact with each other and with
CC themselves (By similarity). High sequence similarity is required for
CC their interaction (By similarity). {ECO:0000250|UniProtKB:A0A218N034,
CC ECO:0000250|UniProtKB:O74420}.
CC -!- SUBCELLULAR LOCATION: [Isoform 1]: Spore membrane
CC {ECO:0000250|UniProtKB:A0A218N034, ECO:0000255}; Multi-pass membrane
CC protein {ECO:0000255}. Vacuole membrane
CC {ECO:0000250|UniProtKB:A0A218N034, ECO:0000255}; Multi-pass membrane
CC protein {ECO:0000255}. Note=Contained within spores expressing the
CC isoform and localizes isoform 2 to the vacuole.
CC {ECO:0000250|UniProtKB:A0A218N034}.
CC -!- SUBCELLULAR LOCATION: [Isoform 2]: Ascus epiplasm

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