功能Filament-forming cytoskeletal GTPase. Required for normal organization of the actin cytoskeleton. Involved in cytokinesis. May play a role in HCV RNA replication.
序列相似性Belongs to the septin family.
翻译后修饰Phosphorylated upon DNA damage, probably by ATM or ATR.
细胞定位Cytoplasm. Cytoplasm > cytoskeleton > spindle. Chromosome > centromere > kinetochore. Cleavage furrow. Midbody. In metaphase cells, localized within the microtubule spindle. At the metaphase plate, in close apposition to the kinetochores of the congressed chromosomes. In cells undergoing cytokinesis, localized to the midbody, the ingressing cleavage furrow, and the central spindle.
