General description
Soluble guanylyl cyclase (sGC) is an obligate hemoprotein enzyme consisting of α and β subunits of ~80 kDa and ~70 kDa, respectively.
Immunogen
synthetic peptide corresponding to amino acid residues 189-207, with N-terminal added lysine, of rat soluble guanylate cyclase 1, conjugated to KLH with glutaraldehyde. The sequence differs in human, bovine and mouse by 1 amino acid.
Application
Anti-Guanylyl Cyclase β1 (ER-19) antibody produced in rabbit is suitable for immunoblotting at a working dilution of 1:2000 using a cytosolic fraction of rat brain, immunoprecipitation at a working antibody amount of 2-3μg using 60-120μg of a cytosolic fraction of rat brain and for immunohistochemistry at 1:400 using trypsin-digested human, bovine and mouse heart tissue.

It has been used as a primary antibody for:
- localization of β1 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, sGCβ1 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+. 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.
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 (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.
