Poly28602_Purified_GDI1_Antibody_1_053119
Western blot of purified anti-GDI1 antibody (Poly28602). Lane 1: Molecular weight marker; Lane 2: 20 µg of human brain cytosol lysate; Lane 3: 20 µg of mouse brain cytosol lysate; Lane 4: 20 µg of rat brain cytosol lysate. The blot was incubated with 0.1 µg/mL of the primary antibody overnight at 4°C, followed by incubation with HRP-labeled donkey anti-rabbit IgG (Cat. No. 406401). Enhanced chemiluminescence was used as the detection system.

Description

The GDI1 gene encodes Rab GDP dissociation inhibitor alpha (aGDI or GDI), a regulatory protein common to all GTPases of the Rab family. GDI binds to inactive GDP-bound GTPases and sequesters them from the membrane to the cytosol to maintain a soluble pool readily available GTPases. GDI dysfunction leads to abnormal membrane accumulation of various GTPases. Mutations in the GDI1 gene are linked to X-lined mental retardation (XLMR), a common human disorder characterized by mental handicap. Similar to human mental retardation patients, GDI knockout mice have marked defects in synaptic function, particularly related to short-term temporal memory. Mechanistically, lack of GDI impairs synaptic vesicle biogenesis and recycling in the hippocampus.

Recommended Usage

Each lot of this antibody is quality control tested by Western blotting. For Western blotting, the suggested use of this reagent is 0.1 - 2.0 µg per ml. For immunohistochemistry on formalin-fixed paraffin-embedded tissue sections, a concentration range of 0.5 - 2.0 µg/ml is suggested. It is recommended that the reagent be titrated for optimal performance for each application.

Antigen Details

Structure
Human GDI is a 447 amino acid protein with a predicted molecular mass of 50 kD.
Distribution

Tissue distribution: Brain
Cellular distribution: Trans-Golgi network and cytosol

Function
GDI regulates the GDP/GTP exchange reaction in most Rab proteins by inhibiting GDP dissociation from them, and subsequent GTP binding. GDI promotes the dissociation of GDP-bound Rab proteins from the membrane and inhibits their activation.
Interaction
Interacts with RHOH, RAB1A, RAB3A, RAB5A and RAB10.
Cellular targets: GDP-bound Rab proteins
