Enables protein domain specific binding activity. Acts upstream of or within several processes, including astral microtubule organization; cytoplasmic sequestering of transcription factor; and nervous system development. Located in centrosome and cytoplasm. Is expressed in several structures, including alimentary system; brain; early embryo; genitourinary system; and sensory organ. Orthologous to human TACC3 (transforming acidic coiled-coil containing protein 3). [provided by Alliance of Genome Resources, Apr 2022]
