WebbSignaling kinases are enzymes that alter the activity, expression, or localization of proteins by altering their phosphorylation. Signaling kinases are located in both the cytoplasm and membranes. They can target different amino acids for phosphorylation, including serine, threonine, or tyrosine. http://www.pibb.ac.cn/html/2016/11/20160033.htm
