Gene Information

General description

The enzyme consists of α and β subunits of ~80kDa and ~70kDa respectively. Both the units are required for catalytic activity. The N-terminal domains of the subunits are essential for the stimulation of the enzyme by NO. Dimerization is mediated by the central portion of GC. The C-terminus domain of both subunits forms the catalytic domain.

Immunogen

synthetic peptide corresponding to amino acid residues 673-690 of rat soluble Guanylyl cyclase α1, conjugated to KLH with glutaraldehyde. The corresponding human sequence differs by 2 amino acids.

Application

Anti-Guanylyl Cyclase α1 antibody produced in rabbit is suitable for immunohistochemistry at a working dilution of 1:100 using trypsin-treated human, bovine and mouse heart tissue and immunoprecipitation at 5-10μg concentration using 60-120μg of a cytosolic fraction of rat brain. It is also suitable for western blot analysis using cytosolic fraction of rat brain at a working dilution of 1:10,000.
It was used as a primary antibody for immunohistochemical:
  • localization of α1 subunits of sGC (soluble guanylate cyclase) in the guinea pig gastrointestinal tract
  • detection of expression of sGC in the vasculature of rat skeletal muscle
  • localization of the functional subunit of NO receptors, sGCα1 in guinea pig caecum

Biochem/physiol Actions

Guanylyl cyclase (GC) catalyzes the conversion of guanosine-5′-triphosphate (GTP) to cyclic guanosine-3′,5-monophosphate (cGMP) and pyrophosphate. This reaction requires Mg2+ or Mn2+.
Guanylyl cyclase (GC) catalyzes the conversion of guanosine-5′-triphosphate (GTP) to cyclic guanosine-3′,5-monophosphate (cGMP) and pyrophosphate. This reaction requires Mg2+ or Mn2+.†† The enzyme (GC) is a major physiological receptor for nitric oxide (NO), an important intra- and intercellular membrane-permeant signaling molecule. Gaseous NO binds to Fe2+ in the prosthetic heme group of the enzyme. NO binding is followed by disruption of the β1 subunit histidine105 bond to iron and activation of the enzyme. GC forms a complex with NO and cGMP and regulates smooth muscle relaxation, inflammation, platelet adhesion and aggregation, pulmonary physiology and neuronal function. It is an important target for NO-releasing and non-NO-releasing activator drugs in human cardiovascular therapy.

Nitric oxide sensitive guanylyl cyclase (NOsGC) is a heterodimeric enzyme formed by an α- and a β₁-subunit. A splice variant (C-α₁) of the α₁-subunit, lacking at least the first 236 amino acids has been described by Sharina et al. 2008

Nitric oxide (NO) is a major signaling molecule in the gastrointestinal tract, and released NO inhibits muscular contraction. The actions of NO are mediated by stimulation of soluble guanylate cyclase (sGC, NO-sensitive GC) and a subsequent increase in cGMP concentration.
