Predicted to enable clathrin adaptor activity. Predicted to be involved in regulation of endocytosis and synaptic vesicle endocytosis. Predicted to act upstream of or within several processes, including cell-substrate junction organization; platelet-derived growth factor receptor signaling pathway; and ruffle assembly. Predicted to be located in cell leading edge; cell projection; and clathrin-coated pit. Predicted to be active in clathrin-coated vesicle and synaptic vesicle. Orthologous to several human genes including STON1-GTF2A1L (STON1-GTF2A1L readthrough). [provided by Alliance of Genome Resources, Apr 2022]
