Function | Adapter protein that provides a link between the endocytic membrane traffic and the actin assembly machinery. Acts as a guanine nucleotide exchange factor (GEF) for CDC42, and thereby stimulates actin nucleation mediated by WASL and the ARP2/3 complex. Plays a role in the assembly and maturation of clathrin-coated vesicles. Recruits FCHSD2 to clathrin-coated pits. Involved in endocytosis of activated EGFR, and probably also other growth factor receptors. Involved in endocytosis of integrin beta-1 (ITGB1) and transferrin receptor (TFR).internalization of ITGB1 as DAB2-dependent cargo but not TFR may involve association with DAB2. Promotes ubiquitination and subsequent degradation of EGFR, and thereby contributes to the down-regulation of EGFR-dependent signaling pathways. In chromaffin cells, required for normal exocytosis of catecholamines. Required for rapid replenishment of release-ready synaptic vesicles at presynaptic active zones. Inhibits ARHGAP31 activity toward RAC1. Isoform 1: Plays a role in synaptic vesicle endocytosis in brain neurons. |
