- Extra Details:
- The kinase suppressor of Ras 1 (KSR1) is a molecular scaffold protein that regulates the activation of the Raf/MEK/extracellular signal-regulated kinase (ERK) signal transduction pathway (1-3). KSR1 expression regulates the intensity and duration of growth factor-induced ERK activation to modulate cell proliferation; H-RasV12-induced transformation and senescence; and adipogenic potential. KSR1 disruption in mammalian models inhibits oncogenic Ras-induced senescence and transformation in vitro and in vivo (4;5). KSR1 translocates to the plasma membrane in response to growth factor treatment and Ras activation; where it forms a complex involving Raf-1; MEK1 and 14-3-3 protein and facilitates the activation of MEK by Raf and of ERK by MEK (6). KSR1 also mediates ERK-dependent negative feedback signaling on Raf; MEK; and KSR1 (7). In non-stimulated cells; KSR1 is sequestered in the cytosol through 14-3-3 protein binding after phosphorylation by C-TAK1 at Ser297 and Ser392. Meanwhile; KSR1 constitutively interacts with MEK and ERK. Upon growth factor stimulation; activated Ras triggers the dephosphorylation of KSR1 at Ser392 by PP2A; leading to the release of 14-3-3 protein from its binding sites. This in turn allows phospho KSR1 to translocate to the cell membrane; where phospho KSR1 forms a complex with Raf; MEK and ERK (8). KSR1 thus potentially enhances the phosphorylation of Raf; MEK and ERK; facilitating the upstream signalling transduction as well as regulating multiple cellular functions by activation of various substrates.
