Any process that initiates the activity of the inactive enzyme MAP kinase kinase during osmolarity sensing. The initiation of the activity of the inactive enzyme JUN kinase kinase (JNKK) activity in response to phosphorylation by a member of the JUN kinase kinase kinase (JNKKK) family, or another upstream kinase. JNKKs are involved in a signaling pathway that is primarily activated by cytokines and exposure to environmental stress. Any process that initiates the activity of the inactive enzyme MAP kinase kinase in the context of conjugation with cellular fusion. A series of reactions that occur within the cell, mediated by protein kinases, which occurs as a result of a single trigger reaction or compound. Any process that initiates the activity of an inactive protein kinase. Any process that initiates the activity of the inactive enzyme MAP kinase kinase in the context of an innate immune response, a defense response mediated by germline encoded components that directly recognize components of potential pathogens. The process of introducing a phosphate group into a molecule, usually with the formation of a phosphoric ester, a phosphoric anhydride or a phosphoric amide. The initiation of the activity of the inactive enzyme MAP kinase kinase by phosphorylation by a MAPKKK. Any process that initiates the activity of the inactive enzyme MAP kinase kinase in the context of cell wall biogenesis, the assembly and arrangement of the cell wall, the rigid or semi-rigid envelope lying outside the cell membrane of plant, fungal and most prokaryotic cells. 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 activates or increases the frequency, rate or extent of protein kinase activity. The process of introducing a phosphate group on to a protein. The covalent alteration of one or more amino acids occurring in a protein after the protein has been completely translated and released from the ribosome.
