Description

General description

Rab18 is a member of the Rab family of small guanosine triphosphatases (GTPases). The Rab family belongs to the Ras superfamily of small guanosine triphosphatases (GTPases). Rab proteins contain conserved regions involved in guanine-nucleotide binding, and hypervariable C-terminal domains with a cysteine motif.

Application

Anti-Rab18 antibody produced in rabbit has been used in:

• immunoblotting
• immunoprecipitation
• immunofluorescence

Biochem/physiol Actions

Rab guanosine triphosphatases (Rab GTPases) are central regulators of membrane trafficking between different subcellular compartments of eukaryotic cells. Their regulatory capacity depends on their ability to cycle between the guanosine diphosphate (GDP)-bound inactive and GTP-bound active states. Activation of a Rab protein is coupled to its association with intracellular membranes. Through their effector proteins, Rab GTPases regulate vesicle formation, actin- and tubulin-dependent vesicle movement and membrane fusion. The conserved regions of Rab proteins are implicated in subcellular targeting. Each Rab protein shows a characteristic subcellular distribution. Therefore, antibodies to Rab proteins may serve as useful tool for studying subcellular localization and membrane organization. Rab18 is involved in retrograde Golgi-endoplasmic reticulum (ER) trafficking.
