Gene

ITSN1

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Acts as guanine nucleotide exchange factor (GEF) specific for the CDC42 GTPase (By similarity). Adapter protein that may provide indirect link between the endocytic membrane traffic and the actin assembly machinery. May regulate the formation of clathrin-coated vesicles. 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. Isoform 1 could be involved in brain-specific synaptic vesicle recycling. Inhibits ARHGAP31 activity toward RAC1.By similarity2 Publications

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

Expressioni

Tissue specificityi

Isoform 2 is ubiquitous in adult and fetal tissues with high expression in skeletal muscle, heart, spleen, ovary, testis and all fetal tissues tested and low expression in thymus, blood, lung, liver and pancreas. Isoform 1 is expressed almost exclusively in the brain, in all brain regions. Not expressed in the spinal cord.

Domaini

SH3-3, SH3-4 and SH3-5, but not SH3-1 and SH3-2 domains, bind to dynamin (By similarity). SH3-1 and SH3-4 bind to ARHGAP31.By similarity
The KLERQ domain binds to SNAP-25 and SNAP-23.By similarity
In an autoinhibited form the SH3 domain 5 may bind intramolecularly to the DH domain, thus blocking the CDC42-binding site.By similarity
