Signaling Pathway
Subsequently, IL-2 was discovered to be a member of a family of cytokines, which also includes IL-4, IL-7, IL-9, IL-15 and IL-21. IL-2 signals through a receptor complex consisting of IL-2 specific IL-2 receptor alpha (CD25), IL-2 receptor beta (CD122) and a common gamma chain (γc), which is shared by all members of this family of cytokines. Binding of IL-2 activates the Ras/MAPK, JAK/Stat and PI 3-kinase/Akt signaling modules.Il-2 leads to the phosphorylation of JAK1 and JAK3.

Famous quotes containing the word pathway:
“And open field, through which the pathway wound,
And homeward led my steps. Magnificent
The morning rose, in memorable pomp,
Glorious as e’er I had beheld—in front,
The sea lay laughing at a distance; near,
The solid mountains shone, bright as the clouds,
Grain-tinctured, drenched in empyrean light;”
—William Wordsworth (1770–1850)
