Ensembl Protein ENSP00000358767
InnateDB Gene IDBG-101022 (DENND2D)
Protein Structure
UniProt Annotation
Function Guanine nucleotide exchange factor (GEF) which may activate RAB9A and RAB9B. Promotes the exchange of GDP to GTP, converting inactive GDP-bound Rab proteins into their active GTP- bound form. {ECO:0000269PubMed:20937701}.
Subcellular Localization Cytoplasm {ECO:0000269PubMed:23182661}.
Disease Associations
Tissue Specificity In bronchial mucosa, mainly expressed in ciliated and basal epithelial cells and weakly in alveolar cells (at protein level). Tends to be down-regulated in lung cancers, immortalized bronchial epithelial cell lines and precancerous lesions. {ECO:0000269PubMed:23182661}.
