|Application ||WB, IHC-P, FC, E|
|Other Accession||Q3U1T9, NP_001182144.1, NP_001182145.1|
|Calculated MW||48260 Da|
|Antigen Region||39-68 aa|
|Other Names||DENN domain-containing protein 1B, Connecdenn 2, Protein FAM31B, DENND1B, C1orf218, FAM31B|
|Target/Specificity||This DENND1B antibody is generated from rabbits immunized with a KLH conjugated synthetic peptide between 39-68 amino acids from the N-terminal region of human DENND1B.|
|Format||Purified polyclonal antibody supplied in PBS with 0.09% (W/V) sodium azide. This antibody is purified through a protein A column, followed by peptide affinity purification.|
|Storage||Maintain refrigerated at 2-8°C for up to 2 weeks. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||DENND1B Antibody (N-term) is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||Guanine nucleotide exchange factor (GEF) for RAB35. Promotes the exchange of GDP to GTP, converting inactive GDP-bound RAB35 into its active GTP-bound form. May play a role in clathrin- mediated endocytosis.|
|Cellular Location||Cytoplasm, cytosol. Cytoplasmic vesicle, clathrin-coated vesicle|
|Tissue Location||Highly expressed in dendritic and natural killer cells and at lower levels in other myeloid lineage cells and in pituitary. Significantly up-regulated in effector memory T- cells as compared with naive T-cells|

Clathrin (see MIM 118955)-mediated endocytosis is a major mechanism for internalization of proteins and lipids. Members of the connecdenn family, such as DENND1B, function as guanine nucleotide exchange factors (GEFs) for the early endosomal small GTPase RAB35 (MIM 604199) and bind to clathrin and clathrin adaptor protein-2 (AP2; see MIM 601024). Thus, connecdenns link RAB35 activation with the clathrin machinery (Marat and McPherson, 2010 [PubMed 20154091]).
