Product Information
Primary Accession Q14C86
Clone Names 81028046
Peptide ID 81028046
Additional Information
Gene ID 26130
Other Names GTPase-activating protein and VPS9 domain-containing protein 1, GAPex-5, Rab5-activating protein 6, GAPVD1, GAPEX5, KIAA1521, RAP6
Target/Specificity The synthetic peptide sequence used to generate the antibody AP6872b was selected from the C-term region of human GAPVD1. A 10 to 100 fold molar excess to antibody is recommended. Precise conditions should be optimized for a particular assay.
Format Synthetic peptide was lyophilized with 100% acetonitrile and is supplied as a powder. Reconstitute with 0.1 ml DI water for a final concentration of 1 mg/ml.
StorageMaintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C.
PrecautionsThis product is for research use only. Not for use in diagnostic or therapeutic procedures.
Protein Information
Name GAPVD1
Synonyms GAPEX5, KIAA1521, RAP6
Function Acts both as a GTPase-activating protein (GAP) and a guanine nucleotide exchange factor (GEF), and participates in various processes such as endocytosis, insulin receptor internalization or LC2A4/GLUT4 trafficking. Acts as a GEF for the Ras-related protein RAB31 by exchanging bound GDP for free GTP, leading to regulate LC2A4/GLUT4 trafficking. In the absence of insulin, it maintains RAB31 in an active state and promotes a futile cycle between LC2A4/GLUT4 storage vesicles and early endosomes, retaining LC2A4/GLUT4 inside the cells. Upon insulin stimulation, it is translocated to the plasma membrane, releasing LC2A4/GLUT4 from intracellular storage vesicles. Also involved in EGFR trafficking and degradation, possibly by promoting EGFR ubiquitination and subsequent degradation by the proteasome. Has GEF activity for Rab5 and GAP activity for Ras.
Cellular Location Membrane; Peripheral membrane protein Endosome. Note=Recruited to the plasma membrane by TRIP10/CIP4 in response to insulin
