GeneCards Summary for KSR2 Gene
KSR2 (Kinase Suppressor Of Ras 2) is a Protein Coding gene. GO annotations related to this gene include protein serine/threonine kinase activity. An important paralog of this gene is MAP3K9.
UniProtKB/Swiss-Prot for KSR2 Gene
Location-regulated scaffold connecting MEK to RAF. Has very low protein kinase activity and can phosphorylate MAP2K1 at several Ser and Thr residues with very low efficiency (in vitro). Interaction with BRAF enhances KSR2-mediated phosphorylation of MAP2K1 (in vitro). Blocks MAP3K8 kinase activity and MAP3K8-mediated signaling. Acts as a negative regulator of MAP3K3-mediated activation of ERK, JNK and NF-kappa-B pathways, inhibiting MAP3K3-mediated interleukin-8 production.
