Related Product Information for anti-PYGB antibody

Rabbit anti Human glycogen phosphorylase BB antibody detects brain glycogen phosphorylase, a regulatory enzyme which catalyses the rate-determining step in glycogen degradation. Mammalian glycogen phosphorylase is found as three major isozymes including muscle (GPMM), liver (GPLL), and brain (GPBB), which can be distinguished by their structural and functional properties as well as by the tissues in which they are expressed. GPBB is thought to function in the release of emergency glucose during stress, and in embryogenesis where it is the predominant isozyme. GPBB is also expressed in the early stages of gastric and colorectal cancers.

NCBI Description

The protein encoded by this gene is a glycogen phosphorylase found predominantly in the brain. The encoded protein forms homodimers which can associate into homotetramers, the enzymatically active form of glycogen phosphorylase. The activity of this enzyme is positively regulated by AMP and negatively regulated by ATP, ADP, and glucose-6-phosphate. This enzyme catalyzes the rate-determining step in glycogen degradation.

Uniprot Description

PYGB: Phosphorylase is an important allosteric enzyme in carbohydrate metabolism. Enzymes from different sources differ in their regulatory mechanisms and in their natural substrates. However, all known phosphorylases share catalytic and structural properties. Belongs to the glycogen phosphorylase family.
