Recombinant Human DENN domain-containing protein 1A (DENND1A)

Function

Guanine nucleotide exchange factor (GEF) regulating clathrin-mediated endocytosis through RAB35 activation. Promotes the exchange of GDP to GTP, converting inactive GDP-bound RAB35 into its active GTP-bound form. Regulates clathrin-mediated endocytosis of synaptic vesicles and mediates exit from early endosomes (PubMed:20154091, PubMed:20937701). Binds phosphatidylinositol-phosphates (PtdInsPs), with some preference for PtdIns(3)P (By similarity)

Subcellular Location

Cytoplasmic vesicle, clathrin-coated vesicle membrane (Peripheral membrane protein); Presynaptic cell membrane

Disease Association

[Genetic variants in DENND1A may play a role in susceptibility to polycystic ovary syndrome (PCOS), the most common endocrine disease among premenopausal women. PCOS is a complex disorder characterized by infertility, hirsutism, obesity, various menstrual disturbances, and enlarged ovaries studded with atretic follicles]

Subunit

Interacts with RAB35 (PubMed:20154091). Interacts with clathrin and with the adapter protein complex 2, AP-2 (PubMed:20154091, PubMed:20937701). Interacts with ITSN1 and SH3GL2 (By similarity). Interacts (when phosphorylated) with YWHAE (PubMed:26055712)
