CC -!- FUNCTION: Polarity-determining protein which forms a conjugate with the
CC ubiquitin-like modifier HUB1. Involved in bud site selection and
CC cellular morphogenesis during conjugation. Required for pseudohyphal
CC growth. {ECO:0000269|PubMed:11923536, ECO:0000269|PubMed:9214378,
CC ECO:0000269|PubMed:9443897}.
CC -!- SUBUNIT: Conjugated with HUB1. HUB1 has not the classical C-terminal
CC Gly residue, so it is still unknown how conjugation may occur.
CC -!- SUBCELLULAR LOCATION: Bud tip. Bud neck. Cytoplasm, cytoskeleton.
CC Note=Sites of polarized growth as bud tip, bud neck and mating
CC projection. Hub1 is necessary for the proper location to mating
CC projections after pheromone alpha treatment.
CC -!- MISCELLANEOUS: Present with 672 molecules/cell in log phase SD medium.
CC {ECO:0000269|PubMed:14562106}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAB63284.1; Type=Erroneous termination; Note=Truncated C-terminus.; Evidence={ECO:0000305};
CC Sequence=DAA09623.2; Type=Frameshift; Evidence={ECO:0000305};
