The 96 kDa protein kinase activated by oncogenic Ras in Xenopus egg extracts is also activated by constitutively active Mek: activation requires serine/threonine phosphorylation
In the Xenopus egg and oocyte system, oncogenic Ras protein can induce cell cycle arrest. The effect of oncogenic Ras on the cell cycle seems to be mediated by the Raf – Mek – Erk pathway of Ras signal transdu...
