Product Description
RAB21 Antibody [AMM02566G] | Leading Biology
Product Category: Monoclonal Antibodies
Host: Mouse
Species Reactivity: H, African Green Monkey
Specificity: This RAB21 antibody is generated from a mouse immunized with a recombinant protein between 1-225 amino acids from the human RAB21.
Cellular Localisation: Endoplasmic reticulum membrane; Lipid-anchor. Golgi apparatus, trans-Golgi network. Golgi apparatus membrane. Early endosome membrane. Cytoplasmic vesicle membrane. Cleavage furrow. Cell projection, neuron projection {ECO:0000250|UniProtKB:P35282}. Note=Colocalizes with ANKRD27 and VAMP7 in neurites (By similarity) . In nonpolarized epithelial Caco-2 cells, found in the endoplasmic reticulum; in polarized cells, observed in vesicles in the apical cytoplasm (PubMed:10887961) . During mitosis, in mid-telophase, localized in the ingressing cleavage furrow (PubMed:18804435) . In late telophase, detected at the opposite poles of the daughter cells, in vesicles at the base of lamellipodia formed by the separating daughter cells (PubMed:18804435) {ECO:0000250|UniProtKB:P35282, ECO:0000269|PubMed:10887961, ECO:0000269|PubMed:18804435}
Molecular Weight: 24348
Clone: Monoclonal
Gene Name: RAB21 (HGNC:18263)
Gene ID: 23011
Function: Small GTPase involved in membrane trafficking control (PubMed:18804435, PubMed:25648148) . During the mitosis of adherent cells, controls the endosomal trafficking of integrins which is required for the successful completion of cytokinesis (PubMed:18804435) . Regulates integrin internalization and recycling, but does not influence the traffic of endosomally translocated receptors in general (By similarity) . As a result, may regulate cell adhesion and migration (By similarity) . Involved in neurite growth (By similarity) . Following SBF2/MTMT13-mediated activation in response to starvation-induced autophagy, binds to and regulates SNARE protein VAMP8 endolysosomal transport required for SNARE-mediated autophagosome-lysosome fusion (PubMed:25648148) . Modulates protein levels of the cargo receptors TMED2 and TMED10, and required for appropriate Golgi localization of TMED10 (PubMed:31455601) .
Summary: Tissue Location: Widely expressed. In jejunal tissue, predominantly expressed in the apical region of the epithelial cell layer of the villi, weak expression, if any, in the crypt epithelium. Capillary endothelium and some cell types in the lamina propria also show expression.
