Immunohistochemistry (IHC)
(MBS9600686 at 1/100 staining Human thyroid cancer tissue by IHC-P. The sample was formaldehyde fixed and a heat mediated antigen retrieval step in citrate buffer was performed. The sample was then blocked and incubated with the antibody for 1.5 hours at 22 degree C. An HRP conjugated goat anti-rabbit antibody was used as the secondary.)

Function: Scaffolding protein that is part of a multiprotein signaling complex. Promotes phosphorylation of Raf family members and activation of downstream MAP kinases. Promotes activation of MAPK1 and/or MAPK3, both in response to EGF and to cAMP. Does not have kinase activity by itself.
Subunit Structure: Interacts with HSP90AA1/HSP90, YWHAE/14-3-3, CDC37, MAP2K1/MEK-1 and MAP2K2/MEK-2 (PubMed:10409742). Interacts with MARK3, PPP2R1A and PPP2CA. Also interacts with RAF and MAPK/ERK, in a Ras-dependent manner. The binding of 14-3-3 proteins to phosphorylated KSR prevents the membrane localization (By similarity). Interacts with isoform 1 of VRK2 (PubMed:20679487). Interacts with AKAP13 and BRAF (PubMed:21102438). Identified in a complex with AKAP13, MAP2K1 and BRAF (By similarity).
Post-translational Modifications: Phosphorylated on Ser-311 and, to a higher extent, on Ser-406 by MARK3. Dephosphorylated on Ser-406 by PPP2CA. In resting cells, phosphorylated KSR1 is cytoplasmic and in stimulated cells, dephosphorylated KSR1 is membrane-associated. Phosphorylated by PKA at Ser-888. Phosphorylation at Ser-888 is required for cAMP-dependent activation of MAPK1 and/or MAPK3 (By similarity).
Similarity: The protein kinase domain is predicted to be catalytically inactive. The domain is sufficient for KSR1 and KSR1-mediated MAP2K1 and MAP2K2 membrane localization. The domain is required but not sufficient for MAP kinase-mediated inhibition of ELK1 phosphorylation (PubMed:10409742).The protein kinase domain is predicted to be catalytically inactive. The domain is sufficient for KSR1 and KSR1-mediated MAP2K1 and MAP2K2 membrane localization. The domain is required but not sufficient for MAP kinase-mediated inhibition of ELK1 phosphorylation.The N-terminal region mediates interaction with BRAF and with membranes. Belongs to the protein kinase superfamily. TKL Ser/Thr protein kinase family.

Product Notes
The KSR1 ksr1 (Catalog #AAA9600686) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The Phospho-KSR1 (Ser392/406) Antibody reacts with Human, Mouse and may cross-react with other species as described in the data sheet. AAA Biotech's KSR1 can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB), Immunohistochemistry (IHC). WB: 1:500-1:2000 IHC: 1:50-1:200. Researchers should empirically determine the suitability of the KSR1 ksr1 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "KSR1, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
