Cytokinesis protein 2

Gene

HOF1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Throughout most of the cell cycle it forms a double ring that coincides with the septins. After the onset of mitosis, forms a ring-like structure which colocalizes with the medial actin ring. Mediates cytoskeletal rearrangements required for cytokinesis. In conjunction with the medial actin ring exhibits contraction-like action.2 Publications
