protein kinases
n. (protein kinase English)
Usage examples of "protein kinases".
There are a number of membrane proteins which can be phosphorylated in this way, some postsynaptic, some presynaptic, and the enzymes responsible for catalysing the phosphorylation are known collectively as protein kinases.
One of these protein kinases is specifically activated by calcium (and is therefore, in another of the acronyms beloved of biochemists, known universally as PKC).
