The localization and translational control of actin mRNA is important for the migration of fibroblasts and is regulated by the activity of the kinase Src (see Figure 18.10). Src is activated by phosphorylation when cell surface receptors bind to signaling molecules. How might this system lead to a cell migrating in a specific direction? How might the cell migrate away from repulsive signals?

Hello, everyone. Here we have a question that says activation of SRC protein chia leads to the localization of act MRN A to the leading edge of the cell, which is the direction the cell will migrate. And the question is which of the following processes causes the SRC protein. Kindness to be activated SRC protein. Kindness contains tyro residues that combine to phosphate groups. Tyro residues have a phosphate binding pocket that allows them to bind to phosphate groups. And it is this binding to the phosphate group that activates the enzyme. So this is called phosphorylation. So our answer is c phosphorylation. Thank you for watching. Bye.
