Protein attributes

Sequence length	1046 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Polarity-determining protein which forms a conjugate with the ubiquitin-like modifier HUB1. Involved in bud site selection and cellular morphogenesis during conjugation. Required for survival during stationary phase. Ref.3 Ref.6
Subunit structure	Conjugated with HUB1. HUB1 has not the classical C-terminal Gly residue, so it is still unknown how conjugation may occur.
Subcellular location	Cytoplasm Ref.4.
