Plays a role in protein trafficking, actin organization and embryonic morphogenesis (PubMed:19798448). Potentially acts as cdc-42 effector (PubMed:25775511). May play a role in hypodermal P-cell nuclear positioning (PubMed:23150597). Together with toca-2, is required for protein trafficking regulating yolk protein clathrin- mediated endocytosis by oocytes during oogenesis and retrograde recycling and the sorting of recycling endosome cargo proteins such as mig-14 (PubMed:19798448, PubMed:25775511). Also, together with toca-2, controls the distribution of actin at cell junctions (PubMed:19798448, PubMed:26578656). {Experimental EvidencePubMed:19798448, Experimental EvidencePubMed:23150597, Experimental EvidencePubMed:25775511, Experimental EvidencePubMed:26578656}.
