15/KSR-1

Proteins of the Ras superfamily play critical roles in the control of normal and neoplastic proliferation. In mammalian cells there are four true Ras proteins (encoded by Ha-ras, N-ras, Ki-rasA, and Ki-rasB). These proteins relay signals from tyrosine kinases at the plasma membrane to the nucleus via a network of Ser/Thr kinases that includes the MAP kinase (Raf-MEK-ERK) pathway. Kinase suppressor of Ras (KSR-1) was discovered in a genetic screen to identify mutations that suppress constitutively active Ras mutants. KSR-1 contains five domains that are conserved areas (CA) in Drosophila, mouse, and human. CA1 is a unique domain, CA2 is a proline-rich domain, CA3 is a cysteine-rich domain, CA4 is a Ser/Thr rich region, and CA5 contains a C-terminal kinase domain similar to that of Raf. In COS7 cells, ceramide induces the autophosphorylation of KSR-1 and KSR-1-induced phosphorylation and activation of Raf. In addition, overexpression of KSR-1 in 293T cells leads to recruitment of MEK to a 700 kDa protein complex and translocates MEK from the soluble to the membrane-associated fraction. Thus, KSR-1 may have important kinase and scaffolding activities during Ras-related signaling.

This antibody is routinely tested by western blot analysis. Other applications were tested at BD Biosciences Pharmingen during antibody development only or reported in the literature.

Purified
Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
