Molecular mechanism for learning and memory is identified
...tion is a fundamental molecular process in which a phosphate
is transferred to a protein, causing the protein to change shape and function. In the case of GAP-43, the protein kinase C (PKC) is the enzyme responsible for its phosphorylation. The researchers first studied four different types of mice and their...
