DescriptionChemiSCREEN™ Human PAC1-long Receptor Membrane Preparation
OverviewHuman ADCYAP1R1 cDNA encoding the long isoform of PAC1
Background InformationPACAP (pituitary adenylyl cyclase-activating peptide) is a peptide that exists in 2 forms, 27 or 38 amino acids, and is related to vasoactive intestinal peptide (VIP). Three related class B GPCRs, PAC1, VPAC1 and VPAC2, bind to PACAP; however, VPAC1 and VPAC2 have a much higher affinity for VIP than does PAC1 (Vaudry et al., 2000). Several splice variants of PAC1 result in proteins that differ at the N-terminus and third intracellular loop; these variants differ in their affinities for PACAP and abilities to activate Gq and Gs. High expression of PAC1 is observed in the CNS and the adrenal medulla. Studies with PAC1-null mice indicate that PAC1 plays important roles in regulation of circadian rhythms, neutrophil migration, and pulmonary vascular tone (Hannibal et al., 2001; Martinez et al., 2005; Otto et al., 2004). Chemicon's PAC1-long membrane preparations are crude membrane preparations made from our proprietary stable recombinant cell lines to ensure high-level of GPCR surface expression; thus, they are ideal HTS tools for screening of antagonists of PAC1-long interactions with PACAP27. The membrane preparations exhibit a Kd of 2.7 nM for [125I]-PACAP27. With 5 µg/well PAC1-long Membrane Prep and 0.75 nM [125]-PACAP27, a greater than 20-fold signal-to-background ratio was obtained.

Biological Information
Entrez Gene Number
Entrez Gene SummaryThis gene encodes type I adenylate cyclase activating polypeptide receptor, which is a membrane-associated protein and shares significant homology with members of the glucagon/secretin receptor family. This receptor mediates diverse biological actions of adenylate cyclase activating polypeptide 1 and is positively coupled to adenylate cyclase. Alternative splicing of two exons of this gene generates four major splice variants, but their full-length nature has not been determined.

UniProt Number
UniProt SummaryFUNCTION: SwissProt: P41586 # This is a receptor for PACAP-27 and PACAP-38. The activity of this receptor is mediated by G proteins which activate adenylyl cyclase. May regulate the release of adrenocorticotropin, luteinizing hormone, growth hormone, prolactin, epinephrine, and catecholamine. May play a role in spermatogenesis and sperm motility. Causes smooth muscle relaxation and secretion in the gastrointestinal tract.
SIZE: 468 amino acids; 53314 Da
SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein.
TISSUE SPECIFICITY: Most abundant in the brain, low expression in the lung, liver, thymus, spleen, pancreas and placenta.
SIMILARITY: SwissProt: P41586 ## Belongs to the G-protein coupled receptor 2 family.
Incubation ConditionsMembranes 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, a GF/C 96-well filter plate is coated with 0.33% polyethyleneimine for 30 min, then washed with 50mM HEPES, pH 7.4, 0.5% BSA. 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, 0.2% BSA, filtered and stored at 4°C Radioligand: [125I] PACAP27 (Perkin Elmer # NEX294) Wash Buffer: 50 mM Hepes, pH 7.4, 500mM NaCl , 0.1% BSA, filtered and stored at 4°C.
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 PACAP27 at 0.75 nM.
