Protein attributes

Sequence length	409 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Required for the ingression of the plasma membrane into the bud neck at the end of cytokinesis, leading to the separation of the mother and daughter cells. Stimulates the synthesis of the primary septum (PS) by CHS2. Ref.5 Ref.6 Ref.7
Subunit structure	Interacts with CYK2, CYK3 and IQG1. Ref.5 Ref.6 Ref.7
Subcellular location	Bud neck. Note: Localizes at the contractile actinomyosin ring at the end of cytokinesis. Recruitment to the bud neck requires either CYK2 or CYK3. Ref.5 Ref.6 Ref.7 Ref.9
Domain	The C2 domain is essential for membrane ingression during cytokinesis, but not for recruitment to the actomyosin ring. Ref.5
Sequence similarities	Belongs to the INN1/fic1 family. Contains 1 C2 domain.
