Información sobre el gen

Descripción general

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.

Inmunógeno

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.

Aplicación

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

Acciones bioquímicas o fisiológicas

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.

Most biological effects of nitric oxide (NO) in the brain are mediated by guanylyl cyclase-coupled NO receptors, whose activation results in increased intracellular cGMP levels. Apart from protein kinase activation little is known about subsequent cGMP signal transduction. In optic

Nitric oxide (NO) is an inhibitory signalling molecule in the gastrointestinal (GI) tract that is released from neurons and from leucocytes during inflammation. NO stimulates soluble guanylate cyclase (sGC), elevates cyclic guanosine 3',5'-monophospate (cGMP), and subsequently activates cGMP-dependent protein kinase

The regulation of vascular soluble guanylyl cyclase (sGC) expression by nitric oxide (NO) is still under discussion. In vitro, NO has been shown to downregulate the expression of sGC but it is unclear if this mechanism is operative in vivo

Increasing evidence implicates overactivation of RhoA as a critical component of the pathogenesis of hypertension. Although a substantial body of work has established that Rac1 functions antagonize RhoA in a broad range of physiological processes, the role of Rac1 in
