Predicted to enable actin binding activity and small GTPase binding activity. Acts upstream of or within regulation of cellular component size. Predicted to be located in perinuclear region of cytoplasm. Is expressed in several structures, including adipose tissue; alimentary system; hemolymphoid system; nervous system; and reproductive system.
