PHYSICAL PROPERTIES

STRUCTURE

motifs/domains	an N-terminal DENN (differentially expressed in neoplastic versus normal cells) domain, a poorly characterized protein module found in multiple proteins of unrelated function
	multiple Src homology 3 (SH3) domain-binding motifs
	a C-terminal peptide motif domain harboring three distinct motifs for binding the alpha-ear of the clathrin adaptor protein 2 (AP-2)

SUBCELLULAR LOCALIZATION	plasma membrane
	intracellular
	intracellular,cytoplasm
text	localize to clathrin patches at the plasma membrane

basic FUNCTION	DENN domain-containing protein of neuronal clathrin-coated vesicles functioning in synaptic vesicle endocytosis
	functions on the endocytic limb of the synaptic vesicle cycle
	functions as a guanine nucleotide exchange factor (GEF) for RAB35 to regulate endosomal membrane trafficking
	activate RAB35 in an endocytic pathway trafficking Shiga toxin to the trans-Golgi network

CELLULAR PROCESS

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

signaling

a component

component of the endocytic machinery functioning in synaptic vesicle endocytosis, providing the first evidence of a role for a DENN domain-containing protein in endocytosis

INTERACTION

DNA

RNA

small molecule

protein

whereas DENND1A and DENND1B activate RAB35 for endosomal trafficking, DENND1C uniquely activates RAB35 for its role in actin regulation
