Through ARL14 activation, controls the movement of MHC class II-containing vesicles along the actin cytoskeleton in dendritic cells. Involved in membrane recycling. Interacts with several phosphatidylinositol phosphate species, including phosphatidylinositol 3,4-bisphosphate, phosphatidylinositol 3,5- bisphosphate and phosphatidylinositol 4,5-bisphosphate. {ECO:0000269|PubMed:12082148, ECO:0000269|PubMed:21458045}. |PH| |Sec7| |ARF guanyl-nucleotide exchange factor activity| |regulation of ARF protein signal transduction| |cleavage furrow| |ruffle membrane| |phospholipid binding| |regulation of Ras protein signal transduction| |regulation of small GTPase mediated signal transduction| |regulation of intracellular signal transduction| |membrane| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp102|Nifuroxazide 5μM R03 exp102]]|-1.81| |[[:results:exp298|Sucrose 20000μM R06 exp298]]|1.84| No correlation found to any other genes in chemogenomics.
