| Name | DENN domain containing 2B |
| Description | This gene was identified by its ability to suppress the tumorigenicity of Hela cells in nude mice. The protein encoded by this gene contains a C-terminal region that shares similarity with the Rab 3 family of small GTP binding proteins. This protein preferentially binds to the SH3 domain of c-Abl kinase, and acts as a regulator of MAPK1/ERK2 kinase, which may contribute to its ability to reduce the tumorigenic phenotype in cells. Three alternatively spliced transcript variants of this gene encoding distinct isoforms are identified. [provided by RefSeq, Jul 2008] |
| Summary |
{"type": "root", "children": [{"type": "p", "children": [{"type": "t", "text": "\n DENND2B is a DENN‐domain protein that functions as a guanine nucleotide exchange factor (GEF) for the Rab GTPase Rab13. In epithelial cells, DENND2B activates Rab13 at the leading edge, where it interacts with the effector protein MICAL‑L2. This interaction is critical for remodeling the cell periphery and promoting dynamic membrane extension, which in turn supports invasive cell behavior—a feature relevant to cancer metastasis."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": "\n "}]}, {"type": "t", "text": "\n "}, {"type": "p", "children": [{"type": "t", "text": "\n In addition, DENND2B plays an important role in epidermal growth factor receptor (EGFR) trafficking. It interacts with the adaptor protein intersectin‑s to promote the recycling of ligand‑free EGFR back to the cell surface. Following EGF stimulation, DENND2B is phosphorylated by protein kinase D, which leads to its dissociation from intersectin‑s and facilitates EGFR’s targeting for degradation. This regulatory mechanism provides insights into how the modulation of DENND2B activity might influence receptor recycling and cancer cell signaling."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "2"}]}, {"type": "t", "text": "\n "}]}, {"type": "rg", "children": [{"type": "r", "ref": 1, "children": [{"type": "t", "text": "Maria S Ioannou, Emily S Bell, Martine Girard, et al.
