Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

<p>This section provides any useful information about the protein, mostly biological knowledge.<p><a href='/help/function_section' target='_top'>More...</a></p>Functioni

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.3 Publications

Caution

KSR2 binds ATP and has very low in vitro protein kinase activity; the physiological relevance of this activity is unknown. KSR2 is proposed to be in an inactive conformation by itself or in complex with MAP2K1. Interaction with BRAF is proposed to induce a conformation change that increases the low intrinsic kinase activity (PubMed:21441910).1 Publication
