May act as a modulator of septin function during cytokinesis in the developing nervous system. Interacts with pnut. During mitosis, detected at the cell cortex in metaphase but is concentrated at the cleavage furrow at telophase. Colocalizes with pnut at the cell cortex. Localizes to the neuropil of the embryonic central nervous system (at protein level). Also detected in third instar larval brain (at protein level). Very low levels detected in 0-6 hour embryos with expression up-regulated after 12 hours of embryogenesis and persisting into adult stages (at protein level). Mutants are viable with a 98.4% hatch rate which is close to the wild-type hatch rate. No apparent defects in the central nervous system. Belongs to the transglutaminase-like superfamily.
