GlycoErase™ PYGB Knockout CHO-K1 Cell Line (CAT#: GLJF-0825-JF362)

Description	GlycoErase™ PYGB knockout CHO-K1 cell line is a CHO-K1 model lacking PYGB, the brain isoform of glycogen phosphorylase. PYGB catalyzes the rate-limiting step of glycogen degradation, regulated by AMP, ATP, and glucose-6-phosphate. This knockout enables studies on glycogen breakdown, metabolic stress responses, and tissue-specific glycogen utilization.

Location	20p11.21
Gene ID	5834
Summary	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.
