GTPase-activating protein for the ADP ribosylation factor family (Probable). Regulates endosome recycling downstream of rab-10 and upstream of arf-6 (PubMed:22869721). Truncated cnt-1: Promotes apoptosis during embryonic development. Produced by caspase ced-3-mediated cleavage, and translocates to the plasma membrane where it prevents the activation of the prosurvival Akt-1/2 and sgk-1 signaling pathway by competing with Akt-1/2 for the binding to PtdIns(3,4,5)P3. Interacts (via C-terminal ankyrin repeat) with rab-10 (GTP-bound form); the interaction is required for cnt-1 recruitment to endosomes. Interacts (via C-terminal ankyrin repeat) with rab-8 (GTP-bound form) and rab-35 (GTP-bound form). Colocalizes with rab-10, rab-8, rab-35 and clathrin chc-1 on recycling endosomes in the intestinal epithelium. Partially colocalizes with early endosome marker rab-5 and to a lesser extent with late endosome marker rme-1. Colocalizes with arf-6 on endosomes of the basolateral recycling pathway. Binds PtdIns(3,4,5)P3 at the plasma membrane. Expressed in embryos. The PH domain binds phosphatidylinositol phosphate (PIP), phosphatidylinositol 4,5-bisphosphate (PIP2) and phosphatidylinositol 3,4,5-trisphosphate (PIP3), and to a lesser extent phosphatidic acid and cardiolipin. Cleaved by caspase ced-3 after Asp-382 and Asp-609. Cleavage at Asp-382 is required for subsequent cleavage at Asp-609. Causes a delay in cell death during embryogenesis characterized by a decrease in the number of cell corpses at the comma and 1,5 fold stage and an increase in the number of cell corpses between the 2-fold and the 3-fold stages.
