Transcription factor required for the mating response; promotes global DNA-binding specificity of Ste12p; subunit of the mRNA m6A methyltransferase (MIS) complex, regulating meiosis at multiple steps, prior to pre-meiotic S phase and during meiotic completion and sporulation; exists as a slower-migrating form during vegetative growth and a fast-migrating pheromone-induced form; putative role in sterol lipid metabolism; homologous to human METTL14, a subunit of a m6A methyltransferase complex
