Protein attributes

Sequence length	880 AA.
Sequence status	Complete.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	Involved in cytokinesis. May hydrolyze GTP. Ref.4
Catalytic activity	GTP + H2O = GDP + phosphate.
Subcellular location	Cytoplasm Potential. Cleavage furrow. Note: During cytokinesis, found in the cleavage furrow. Ref.4
Developmental stage	Expression begins during cell cycle progression, between 12 and 24 hours after germination. Reach a maximum around mid-log phase and disappear during the stationary phase. Expressed in the central funnel of cells of migrating slugs and at the top of rising culminants. Not expressed until the slug stage. Ref.2 Ref.4
Induction	Induced by STATa. Ref.3
Disruption phenotype	Produced cells are larger and a large amount of them contains more than 2 nuclei. Ref.4
Sequence similarities	Belongs to the dynamin family.
