ITSN1

Functionⁱ

Adapter protein that provides a link between the endocytic membrane traffic and the actin assembly machinery (PubMed:11584276, PubMed:29887380). Acts as guanine nucleotide exchange factor (GEF) for CDC42, and thereby stimulates actin nucleation mediated by WASL and the ARP2/3 complex (PubMed:11584276). Plays a role in the assembly and maturation of clathrin-coated vesicles (By similarity). Recruits FCHSD2 to clathrin-coated pits (PubMed:29887380). Involved in endocytosis of activated EGFR, and probably also other growth factor receptors (By similarity). 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 (PubMed:22648170). 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 (By similarity). Inhibits ARHGAP31 activity toward RAC1 (PubMed:11744688).By similarity4 Publications

Isoform 1: Plays a role in synaptic vesicle endocytosis in brain neurons.By similarity

Caution

Studies in clathrin-mediated endocytosis of ITGB1 and TFR used a siRNA mixture of ISTN1 and ISTN2, and a Dab2 mutant with impaired binding to EH domain-containing proteins EPS15 and ITSN1 suggesting a partially overlapping role of the EH domain-containing proteins.1 Publication
