We have previously reported that serine at position 345 in fission yeast Chk1 is phosphorylated in vivo and is required to activate Chk1 kinase activity in the presence of DNA damage [12].
It has been previously shown that reduction of LLO is required to activate its lytic activity and this is achieved by the enzyme γ-interferon-inducible lysosomal thiol reductase (GILT, also called Ifi30) [22].
Tyrosine phosphorylation is required to activate Syk kinase activity and function.
Essentially, greater spreading activation is required to activate words that have lower frequencies, i.e., are further out in the lexical/semantic network.

These results indicate that PKR catalytic activity is required to activate PP2A that results in dephosphorylation of Bcl-2.
It has been postulated that sustained JNK activation is required to activate death-promoting downstream targets such as Bim and Bak [ 41].
For example, activation of CIPK20 is required to activate the ABA signaling pathway involved in seed germination and growth elongation inhibition in A. thaliana (Gong et al. 2002).
This data strongly supports our previous conclusion that the kinase activity of RIPK1 is required to activate caspases in the skin.
However, forest management planning is required to activate the health-restorative function of a forest.
For the operation of RRAM, an irreversible forming procedure is required to activate the as-fabricated RRAM cells.
