    • Interacts with HSP90AA1/HSP90, YWHAE/14-3-3, CDC37, MAP2K1/MEK-1 and MAP2K2/MEK-2 (PubMed:10409742). Interacts with MARK3, PPP2R1A and PPP2CA. Also interacts with RAF and MAPK/ERK, in a Ras-dependent manner. The binding of 14-3-3 proteins to phosphorylated KSR prevents the membrane localization (By similarity). Interacts with isoform 1 of VRK2 (PubMed:20679487). Interacts with AKAP13 and BRAF (PubMed:21102438). Identified in a complex with AKAP13, MAP2K1 and BRAF (By similarity).

Post-translational modifications for KSR1 Gene

  • Phosphorylated on Ser-311 and, to a higher extent, on Ser-406 by MARK3. Dephosphorylated on Ser-406 by PPP2CA. In resting cells, phosphorylated KSR1 is cytoplasmic and in stimulated cells, dephosphorylated KSR1 is membrane-associated. Phosphorylated by PKA at Ser-888. Phosphorylation at Ser-888 is required for cAMP-dependent activation of MAPK1 and/or MAPK3 (By similarity).
