KSR1
KSR1 (Kinase suppressor of Ras 1) is a protein kinase, an enzyme that switches other proteins on by adding phosphate groups. In the public catalogues the evidence so far is association rather than a proven role.
Overview
Part of a multiprotein signalling complex which promotes phosphorylation of Raf family members and activation of downstream MAP kinases. Independently of its kinase activity, acts as MAP2K1/MEK1 and MAP2K2/MEK2-dependent allosteric activator of BRAF; upon binding to MAP2K1/MEK1 or MAP2K2/MEK2, dimerises with BRAF and promotes BRAF-mediated phosphorylation of MAP2K1/MEK1 and/or MAP2K2/MEK2. Promotes activation of MAPK1 and/or MAPK3, both in response to EGF and to cAMP.
Open Targets scores its association with cancer at 0.63 (direct and indirect evidence; datatypes literature 0.93, affected pathway 0.97, animal model 0.57, genetic association 0.00).

- 1 · What it is
KSR1 (Kinase suppressor of Ras 1) is a protein kinase, an enzyme that switches other proteins on by adding phosphate groups. In the public catalogues the evidence so far is association rather than a proven role.
- 2 · What goes wrong in cancer
Part of a multiprotein signalling complex which promotes phosphorylation of Raf family members and activation of downstream MAP kinases.
- 3 · How drugs use it
No product in this corpus aims at KSR1 yet. Kinases are switched on by binding ATP inside the cell, so most drugs are small molecules shaped to plug that ATP pocket.

Biology
Part of a multiprotein signalling complex which promotes phosphorylation of Raf family members and activation of downstream MAP kinases. Independently of its kinase activity, acts as MAP2K1/MEK1 and MAP2K2/MEK2-dependent allosteric activator of BRAF; upon binding to MAP2K1/MEK1 or MAP2K2/MEK2, dimerises with BRAF and promotes BRAF-mediated phosphorylation of MAP2K1/MEK1 and/or MAP2K2/MEK2. Promotes activation of MAPK1 and/or MAPK3, both in response to EGF and to cAMP. Its kinase activity is unsure. Some protein kinase activity has been detected in vitro, however the physiological relevance of this activity is unknown. Location: Cytoplasm; Membrane; Cell membrane; Cell projection, ruffle membrane (UniProt). Locus 17q11.2 (HGNC).
Notes
top- Written by scripts/fetch-cancer-genes.ts from CIViC, Open Targets, IntOGen, HGNC and UniProt; the function text is UniProt's, condensed and in UK spelling. Roles: none stated by the sources. Evidence tier "association-only" is the strongest of those signals.
- Prevalence not recorded: none of the sources gives a positivity rate.
