General description

Monoclonal Anti-Rab9 (mouse IgG1 isotype) is derived from the hybridoma Rab9-29 produced by the fusion of mouse cells (NS1 cells) and splenocytes from BALB/c mice. Ras-related protein Rab-9A (Rab9) is a member of the Rab family of small guanosine triphosphatases (GTPases). The gene Rab9 is mapped to human chromosome Xp22.2. Rab9 GTPase is localized predominantly to late endosomes.

Specificity

Monoclonal Anti-Rab9 recognizes human, canine, rat, mouse and hamster Rab9 (approx. 23 kDa)

Immunogen

synthetic peptide corresponding to amino acids 187-200 of human Rab9, conjugated to KLH.

Application

Monoclonal Anti-Rab9 antibody produced in mouse has been used in:
  • western blotting
  • enzyme-linked immunosorbent assay(ELISA)
  • immunoprecipitation
  • immunocytochemistry

Biochem/physiol Actions

Ras-related protein Rab-9A (Rab9) guanosine triphosphatase (GTPase) is required for the transport of mannose 6-phosphate receptors (MRPs) from endosomes to the trans-Golgi network (TGN). Rab GTPases are central regulators of membrane trafficking between the different subcellular compartments of the eukaryotic cell. 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 tail-interacting protein of 47 kDa (TIP47). This interaction is required for Rab9 stability on late endosomes and may be crucial for vesicular transport in the virus life cycle.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Storage and Stability

For continuous use, store at 2-8 °C for up to one month. For extended storage, freeze in working aliquots. Repeated freezing and thawing, or storage in "frost-free" freezers, is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilution samples should be discarded if not used within 12 hours.

The small GTPase Rab9 has long been described as a protein that mediates endosome-to-trans-Golgi Network (TGN) transport, and specifically mannose-6-phospate receptor (MPR) recycling. However, studies have challenged this view by showing that Rab9 also is connected to sorting pathways toward
