General description
Phosphorylase kinase contains four subunits each containing an α, β, γ, and sigma component. The sigma component binds 4 calcium molecules and is termed calmodulin while the γ unit acts as the catalytic subunit.
Application
Phosphorylase kinase from rabbit muscle has been used in a study to assess features of glycogen phosphorylase. It has also been used in a study to investigate the activation of different forms of muscle phosphorylase kinase by actin.
Unit Definition
One unit will form 1.0 μmolar unit of phosphorylase a from phosphorylase b per min at pH 7.7 at 30°C in the presence of ATP.
Physical form
Lyophilized powder containing (NH4)2SO4, sucrose, β-glycerophosphate and dithioerythritol
Storage Class
11 - Combustible Solids

The activities of glycogen phosphorylases a and b from the body wall musculature of the marine worm Arenicola marina (Annelida, Polychaeta) were determined after various periods of anoxia. Already under normoxic conditions one third of the total activity was produced

The endoplasmic reticulum transmembrane receptor Ire1 senses over-accumulation of unfolded proteins in the endoplasmic reticulum and initiates the unfolded protein response (UPR). The cytoplasmic portion of Ire1 has a protein kinase domain (KD) and a kinase extension nuclease (KEN) domain

Calcium/calmodulin-stimulated protein kinases can be classified as one of two types - restricted or multifunctional. This family of kinases contains several structural similarities: all possess a calmodulin binding motif and an autoinhibitory region. In addition, all of the calcium/calmodulin-stimulated protein

The chloroplast protein CP12 forms a multi-enzyme complex with the Calvin-Benson cycle enzymes phosphoribulokinase (PRK) and NADP-glyceraldehyde-3-phosphate dehydrogenase (GAPDH). PRK and GAPDH are inactivated when present in this complex, a process shown in vitro to be dependent upon oxidized CP12.

Angiogenesis is essential for development and tumor progression. With the aim of identifying new compound inhibitors of the angiogenesis process, we used an established enhanced green fluorescent protein-transgenic zebrafish line to develop an automated assay that enables high-throughput screening of
