Additional Information

Alternative name: GABA(A) receptor-associated protein (GABARAP) (n-terminal region)

Immunogen: A synthetic peptide as a part of human, rat, mouse GABA(A) receptor-associated protein (GABARAP, MM46, FLC3B) conjugated to immunogenic carrier protein has been used as the immunogen.

Format: Lyophilized

Description: Autophagy is the process by which endogenous proteins and damaged organelles are destroyed intracellularly.autophagy is postulated to be essential for cell homeostasis and cell remodeling during differentiation, metamorphosis, non-apoptotic cell death, and aging. Reduced levels ofautophagy have been described in some malignant tumors, and a role forautophagy in controlling the unregulated cell growth linked to cancer has been proposed. GABARAP belongs ot a large family of proteins that mediate intracellular membrane trafficking and/or fusion. GABARAP binds not only to GABA, type A but also to tubulin, gephrin, and ULK1. May play a role in intracellular transport of GABA(A) receptors and its interaction with the cytoskeleton. It interacts with GPHN and NSF; interacts with GABRG2, beta-tubulin and ULK1. SUBCELLULAR LOCATION: Intracytoplasmic membrane. Cytoplasm, cytoskeleton. Note: Largely associated with intracellular membrane structures including the Golgi apparatus and post-synaptic cisternae. Colocalizes with microtubules. TISSUE SPECIFICITY: Heart, brain, placenta, liver, skeletal muscle, kidney and pancreas. Also known as: GABA(A) receptor-associated protein, GABARAP.

Specificity: Appears to be specific for GABARAP.

Application Details

Application Notes: IHC, WB. Use at a dilution of 1 : 100 to 1 : 2000. The optimal dilution should be determined by the end user. Not yet tested in other applications.

Purity: whole serum

Storage: Maintain the lyophilised/reconstituted antibodies frozen at -20°C for long term storage and refrigerated at 2-8°C for a shorter term. When reconstituting, glycerol (1:1) may be added for an additional stability. Avoid freeze and thaw cycles.

Research Area: Autophagy

Restrictions: For Research Use only
