Descripción

Descripción general

FUNCTION: SwissProt: O43603 # Receptor for the hormone galanin and for GALP. The activity of this receptor is mediated by G proteins that activate the phospholipase C/protein kinase C pathway (via Gq) and that inhibit adenylyl cyclase (via Gi).
SIZE: 387 amino acids; 41700 Da
SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein.
TISSUE SPECIFICITY: Expressed abundantly within the central nervous system in both hypothalamus and hippocampus. In peripheral tissues, the strongest expression was observed in heart, kidney, liver, and small intestine.
SIMILARITY: SwissProt: O43603 ## Belongs to the G-protein coupled receptor 1 family.

Aplicación

Radioligand binding assay and GTPγS binding.

Forma física

One package contains enough membranes for at least 200 assays (units), where an unit is the amount of membrane that will yield greater than 20-fold signal:background with ¹²⁵I-labeled galanin at 0.5 nM.

Liquid in packaging buffer: 50 mM Tris pH 7.4, 10% glycerol and 1% BSA with no preservatives.
Packaging method: Membranes protein were adjusted to the indicated concentration in packaging buffer, rapidly frozen, and stored at -80°C.

Almacenamiento y estabilidad

Maintain frozen at -70°C for up to 2 years. Do not freeze and thaw.

Nota de análisis

Membranes are mixed with radioactive ligand and unlabeled competitor (see Figures 1 and 2 for concentrations tested) in binding buffer in a nonbinding 96-well plate, and incubated for 1-2 h. Prior to filtration, an FC 96-well harvest plate (Millipore cat. # MAHF C1H) is coated with 0.33% polyethyleneimine for 30 min, then washed with 50mM HEPES, pH 7.4. Binding reaction is transferred to the filter plate, and washed 3 times (1 mL per well per wash) with Wash Buffer. The plate is dried and counted.

Binding buffer: 50 mM Hepes, pH 7.4, 5 mM MgCl₂, 1 mM CaCl₂, filtered and stored at 4°C
Radioligand: [¹²⁵I] galanin (Perkin Elmer # NEX333)
Wash Buffer: 50 mM Hepes, pH 7.4, 500mM NaCl, filtered and stored at 4°C.
