WebDec 4, 2024 · Phosphorylase kinase is a polymer of 16 subunits, four each of alpha, beta, gamma and delta. The alpha subunit includes the skeletal muscle and hepatic isoforms, and the hepatic isoform is encoded by this gene. The beta subunit is the same in both the muscle and hepatic isoforms, and encoded by one gene. Web7. A signaling kinase (kinase A) in a signaling pathway phosphorylates another kinase called kinase B, activating it. Kinase B in turn phosphorylates kinase C (another kinase in the pathway), activating it. Kinase B also phosphorylates phosphatase B, which has kinase B as its substrate. This is an example of: Answer: a. Signal amplification. 8.
