Due to the inherent limitations of infectious agent testing, investigators must exercise extreme caution when handling cells provided by Creative Biolabs, treating all cells as potentially biohazardous.

Target	PHKB
Full Name	Phosphorylase Kinase Regulatory Subunit Beta
Location	16q12.1
Gene ID	5257
Summary	Phosphorylase kinase is a 16-subunit enzyme containing alpha, beta, gamma, and delta subunits. The alpha subunit encodes muscle and liver isoforms via separate genes. The beta subunit, encoded by this gene, is the same in both forms. The gamma subunit contains the catalytic site, and the delta subunit (a calmodulin) controls calcium sensitivity. Mutations cause glycogen storage disease type 9B, affecting liver and muscle. Pseudogenes are found on chromosomes 14 and 20.
