In February 28 Nature, Tsuneaki Asai and colleagues from Harvard Medical School, show that in plants the MAP kinase signalling cascade is involved in activation of the innate immune system and confers ...

Signal binding to membrane receptor tyrosine kinases (RTKs) activates an enzyme called a kinase. Learn how kinases initiate a signaling cascade that relays information to the nucleus.

When replication stress is encountered, as during HU exposure, signals are transmitted through a kinase cascade. The paths compared between species are shown, and the given proteins in the pathway ...
