indirect immunofluorescence: 5-10 μg/mL using rat NRK and mouse NIH3T3 cells fixed and permeabilized with 3% paraformaldehyde followed by 0.4% saponin western blot: 5-10 μg/mL using whole extract of human A431 cells
Rab9 is a member of the Rab family of guanosine triphosphatases (GTPases). Rab9 GTPase is localized predominantly to late endosomes. Rab proteins contain conserved regions involved in guanine nucleotide binding, and hypervariable COOH-terminal domains with a cysteine motif implicated in subcellular targeting.
免疫原
synthetic peptide corresponding to amino acid residues 188-200 of human Rab9, conjugated to KLH.
アプリケーション
Anti-Rab9 from rabbit has been used in immunoblotting and immunofluorescence.
生物化学的／生理学的作用
Rab9 GTPase is required for the transport of mannose 6-phosphate receptors (MPRs) from endosomes to the trans-Golgi network (TGN). Rab9 GTPase in its GTP bound conformation binds specifically to an effector protein named p40 that stimulates the transport of mannose 6-phosphate receptors (MPRs) from endosomes to the TGN. Rab9 also interacts with the vesicle cargo selection protein TIP47 (tail-interacting protein of 47 kDa). This interaction is required for Rab9 stability on late endosomes. Anti-Rab9 antibodies may be used as a marker for late endosomes.

Rab9 GTPase is required for the transport of mannose 6-phosphate receptors from endosomes to the trans-Golgi network in living cells, and in an in vitro system that reconstitutes this process. We have used the yeast two-hybrid system to identify proteins
