Is predicted to encode a protein with the following domains: CLASP N-terminal domain; CLASP N terminal; Armadillo-like helical; TOG domain; and Armadillo-type fold. 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.
