RI-STAD-2

RI-STAD-2 is a high-affinity interfering peptide that regulates the subunit RI of protein kinase A (PKA). RI-STAD-2 interferes with the binding of AKAPs and PKA-RI by simulating the interaction between AKAPs' α-helix domain and PKA-RI's dimerization/anchoration (D/D) domain, thereby affecting PKA activity and intracellular localization. RI-STAD-2 can be used to study the role of AKAPs interaction with PKA-RI in pathological processes such as cardiovascular disease and cancer.

Protocols

All Signal Pathway Related

Research Protocol for Cardiovascular Diseases
Cardiovascular disease can be modeled as maladaptive cardiac remodeling, where ischemic injury or pressure overload activates inflammatory signaling, fibroblast activation, extracellular-matrix deposition, cardiomyocyte hypertrophy, vascular remodeling, and progressive ventricular dysfunction. The TGF-β/SMAD axis is a central profibrotic pathway after myocardial injury and pressure overload, while innate immune and cytokine pathways regulate leukocyte recruitment, scar formation, and adverse remodeling. Key unresolved questions include which inflammatory signals are reparative versus harmful, when fibrosis is protective versus maladaptive, and whether pathway inhibition improves function without weakening necessary infarct healing or compensatory remodeling.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
