General description

Kinase Suppressor of Ras (KSR) is a positive effector of Ras signalling pathway. Initially discovered in Drosophila and C. elegans, the KSR family of proteins is structurally similar but distinct from the Raf Family. In response to Ras activation, KSR translocates from the cytoplasm to the plasma membrane and may act as a scaffolding protein to assemble a MAPK signalling complex. KSR interacts with Raf-1, MEK1/2 and ERK1/2 and this interaction is required for a signalling cascade downstream of Ras. Thus KSR plays an important role in survival, proliferation, differentiation, growth and transformation of cells. KSR mediates Ras-dependent signals that are required for neuronal differentiation and functioning of central nervous system
Monoclonal Anti-KSR specifically reacts with mouse KSR (~100 kDa).

Immunogen

recombinant KSR fragment (amino acids 118-248) from mouse.

Application

Anti-KSR is suitable for immunoblotting at a working concentration of 0.5-1.0 μg/mL using human 293T cells expressing mouse KSR. The antibody may be used for immunocytochemistry and protein microarray applications.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Preparation Note

Purified from culture supernatant of hybridoma cells grown in a bioreactor.

By screening for mutations that suppress the vulval defects caused by a constitutively active let-60 ras gene, we identified six loss-of-function alleles of ksr-1, a novel C. elegans gene. Our genetic analysis showed ksr-1 positively mediates Ras signaling and functions

Kinase suppressor of Ras (KSR) is an evolutionarily conserved component of Ras-dependent signaling pathways. Here, we find that murine KSR (mKSR1) translocates from the cytoplasm to the plasma membrane in the presence of activated Ras. At the membrane, mKSR1 modulates

Kinase Suppressor of Ras (KSR) is an intriguing component of the Ras pathway that was first identified by genetic studies performed in Drosophila melanogaster and Caenorhabditis elegans. In both organisms, inactivating mutations in KSR suppress the phenotypic effects induced by

Kinase suppressor of Ras (KSR) is an evolutionarily conserved component of Ras-dependent signaling pathways. Here, we report the identification of B-KSR1, a novel splice variant of murine KSR1 that is highly expressed in brain-derived tissues. B-KSR1 protein is detectable in

Genetic screens for modifiers of activated Ras phenotypes have identified a novel protein, kinase suppressor of Ras (KSR), which shares significant sequence homology with Raf family protein kinases. Studies using Drosophila melanogaster and Caenorhabditis elegans predict that KSR positively regulates
