Any process that initiates the activity of an inactive protein kinase. MAPKKK cascade involved in signal transduction in response to change in osmotic conditions. The initiation of the activity of the inactive enzyme MAP kinase kinase by phosphorylation by a MAPKKK. The series of molecular signals initiated in response to osmotic change. A cascade of at least three protein kinase activities culminating in the phosphorylation and activation of a MAP kinase. MAPKKK cascades lie downstream of numerous signaling pathways. Any process that initiates the activity of the inactive enzyme MAP kinase kinase during osmolarity sensing. The process of introducing a phosphate group on to a protein.
