Janus kinases (JAKs) are non-receptor tyrosine kinases which play the key role in JAK-STAT signaling pathway. A large number of cytokines depend on JAK including interleukin (IL)-2, IL-4, IL-7, IL-9, IL-15 and IL-21. Jak kinases are involved in malignant cell growth and survival. Jak kinases have been shown to modulate activation of Ras-Raf-MAP kinase pathways which are implicated in malignant transformation. The function of Jak kinases is also related to Abl. Jak kinases have been also implicated in the regulation of p53-dependent cell-cycle arrest and apoptosis, for example, Jak kinases can regulate the levels of Bcl-XL, Bcl-2 and Bax expression by their effects on Stats and other receptor linked pathways such as the PI-3 kinase and the Ras-MAPK pathways.
