DENN domain containing 1A (DENND1A) acts as a guanine nucleotide-exchange factor and plays a vital role in membrane trafficking by interacting with members of the Rab family of small guanosine triphosphatase (GTPases). The encoded protein interacts with lipids, mainly phosphoinositol-3-phosphate and other endocytosis/endosome proteins. DENND1A is also implicated in endosomal recycling and aberrations in the protein function might alter insulin secretion. Elevated expression/Mutation in the gene is associated with the development of polycystic ovary syndrome (PCOS).

General description

DENN domain containing 1A (DENND1A) gene with 22 exons, spanning 500,000 bases on genomic DNA, is encoded by the gene mapped to human chromosome 9q22.32. DENND1A belongs to the family of 18 human genes, called “connecdenns”. The encoded protein contains clathrin-binding domain involved in endocytosis and receptor-mediated turnover.1 DENND1A is widely expressed, but at high levels in brain and kidneys.”
