Regulates the activity of DOCK guanine nucleotide exchange factors (GEFs) (PubMed:11595183, PubMed:11703939, PubMed:20679435, PubMed:32651375, PubMed:27476657). Acts in association with DOCK1, DOCK2, DOCK4 and CRK (PubMed:11595183, PubMed:20679435, PubMed:32651375, PubMed:27476657). Involved in cytoskeletal rearrangements required for phagocytosis of apoptotic cells and cell motility (PubMed:11595183). {ECO:0000269|PubMed:11595183, ECO:0000269|PubMed:11703939, ECO:0000269|PubMed:20679435, ECO:0000269|PubMed:27476657, ECO:0000269|PubMed:32651375}. This is the function of ENSG00000062598 (ELMO2, engulfment and cell motility 2).
