Is predicted to encode a protein with the following domains: TOG domain; Armadillo-type fold; CLASP N-terminal domain; HEAT repeat; Armadillo-like helical; and CLASP N terminal. Is an ortholog of C. elegans cls-2. In C. elegans, cls-2 is involved in several processes, including cytoplasmic streaming; microtubule cytoskeleton organization; and nuclear chromosome segregation.
