GlycoErase™ PHKB Knockout HepG2 Cell Line (CAT#: GLJF-0825-JF669)

Description	GlycoErase™ PHKB knockout HepG2 cell line eliminates PHKB, which encodes the beta regulatory subunit of phosphorylase kinase, expressed in both liver and muscle. Mutations cause glycogen storage disease type IXB. This knockout supports research into regulatory control of glycogen breakdown, metabolic defects, and calcium-dependent signaling in liver cells.

Target	PHKB
Full Name	Phosphorylase Kinase Regulatory Subunit Beta
Location	16q12.1
Gene ID	5257
Summary	This multi-subunit kinase contains the same beta subunit in both liver and muscle isoforms, and it is encoded by this gene. The gamma unit provides enzymatic activity, with the delta (calmodulin) regulating calcium sensitivity. Mutations are linked to glycogen storage disease type 9B. Two pseudogenes are located on chromosomes 14 and 20.
