W H M R Mk Endogenous 78 Rabbit IgG

Applications Key:  W=Western Blotting
Reactivity Key:  H=Human  M=Mouse  R=Rat  Mk=Monkey
Species cross-reactivity is determined by western blot. Species enclosed in parentheses are predicted to react based on 100% sequence homology.

Specificity / Sensitivity

PKG-1 (C8A4) Rabbit mAb detects endogenous levels of total PKG-1 protein, including both α and β isoforms. The antibody does not cross-react with PKG-2.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to cental residues of human PKG-1.

Background

Cyclic GMP-dependent kinases (cGK/PKG) belong to the AGC family of serine/threonine protein kinases. In mammals, two genes encode PKG-1 and PKG-2. Alternative PKG-1 splicing yields α and β isoforms, which display tissue-specific expression patterns in humans (1). All PKG family members are activated by increased cellular cGMP, which binds to the enzyme's regulatory domain inducing a conformational change and leading to enzyme activation. cGMP levels are increased through the activation of guanylyl cyclases, a process known to occur in part through nitric oxide (NO) signaling (2).In addition to well established roles in platelet activation and smooth muscle relaxation (3), PKG signaling is important in many biological processes including cardiac contractility, axon guidance, bone growth, contraction of intestinal smooth muscle and erectile dysfunction (4).
