Detection of Human, Mouse, and Rat Raf‑1 antibody by Western Blot.

Detection of Human, Mouse, and Rat Raf‑1 by Western Blot.

Western blot shows lysates of MCF-7 human breast cancer cell line, HepG2 human hepatocellular carcinoma cell line, A431 human epithelial carcinoma cell line, L-929 mouse fibroblast cell line, and NRK rat normal kidney cell line. PVDF Membrane was probed with 1 µg/mL of Mouse Anti-Human/Mouse/Rat Raf-1 Monoclonal Antibody (Catalog # MAB4540) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for Raf-1 at approximately 74 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 3.
Raf-1 antibody in Human Liver by Immunohistochemistry (IHC-P).

Raf‑1 in Human Liver.

Raf-1 was detected in immersion fixed paraffin-embedded sections of human liver array using Mouse Anti-Human/Mouse/Rat Raf-1 Monoclonal Antibody (Catalog # MAB4540) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Lower panel shows a lack of labeling if primary antibodies are omitted and tissue is stained only with secondary antibody followed by incubation with detection reagents.

Simple Western lane view shows lysates of MCF‑7 human breast cancer cell line, loaded at 0.2 mg/mL. A specific band was detected for Raf‑1 at approximately 75 kDa (as indicated) using 10 µg/mL of Mouse Anti-Human/Mouse/Rat Raf‑1 Monoclonal Antibody (Catalog # MAB4540). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Detection of Raf-1 by Western Blot

CRAF activity is sufficient to drive macropinocytosis. Overexpression of constitutively active mutants of the CRAF kinase (S259A or S257L) activates the EV uptake, causes phenotypic transformation and triggers formation of ruffle structures. (a) Western blotting documents overexpression of the CRAF kinase mutants in IEC18 cells including IEC18‐CRAF/S259A and IEC18‐CRAF/S257L cells. (b) Flow cytometry indicates the increased uptake of fluorescent RAS3 EVs by IEC18‐CRAF/S259A and IEC18‐CRAF/S257L relative to RAS3 cells. CRAF mediated EV uptake is obliterated by a specific CRAF inhibitor GW5407 (flow cytometry, three biological replicates for RAS3 and GW5074‐treated cells and six for control CRAF mutant IEC18 cells). (c) Confocal images illustrating a dramatic morphological transformation coupled with the generation of ruffle structures and increased uptake of fluorescent EVs by IEC18‐CRAF/S259A and IEC18‐CRAF/S257L cell lines compared to parental IEC18 cells. (d) Confocal images of immunofluorescent staining show that intracellular distribution of the endogenous RAS protein is re‐organized following activated CRAF expression. RAS signal was enhanced and clustered around ruffle region in contrast to its dimmer appearance and distribution around plasma membrane in non‐transformed cells Image collected and cropped by CiteAb from the following open publication (https://pubmed.ncbi.nlm.nih.gov/34136107), licensed under a CC-BY license.

CRAF is required for particle macropinocytosis by HRAS transformed cells. (a) Western blotting documenting the downregulation of CRAF by siRNA in RAS3 cells. (b) Flow cytometry illustrates the reduced EV uptake by RAS3 cells following CRAF down‐regulation. (c to e) Confocal images documenting the decreased 70‐kDa dextran and EV uptake in CRAF siRNA‐treated RAS3 cells (c). However, transferrin uptake was not affected in CRAF siRNA treated RAS3 cells (d). Quantification of EV uptake in confocal images; fluorescent deposit counting was conducted in 3 randomly taken images of individual cells Image collected and cropped by CiteAb from the following open publication (https://pubmed.ncbi.nlm.nih.gov/34136107), licensed under a CC-BY license.

Signalling intermediates of the RAS/CRAF macropinocytosis pathway and its impact on experimental metastasis. (a) Phosphorylation of myosin phosphatase (MYPT) in cells harbouring transformed CRAF and RAS. Confocal images point to co‐localization between CRAF and pMYPT (T696) in IEC18‐CRAF/S257L and RAS3 cells. Additional co‐localization images were represented in Figure S9. (b and c) Metastasis assays: Control and EIPA pre‐treated (19 h) RAS3 cells were injected to the YFP‐SCID mouse via tail vein (n = 8 for control and n = 9 for EIPA pre‐treated RAS3 cells). After 4 weeks, mice were sacrificed and lung tissues were extracted to enumerate metastatic nodules. Additional biological replicate in NSG mice (n = 7) are presented in Figure S12C Image collected and cropped by CiteAb from the following open publication (https://pubmed.ncbi.nlm.nih.gov/34136107), licensed under a CC-BY license.

Background: Raf-1

The Raf serine/threonine kinases are effectors of Ras that function as MAP3Ks in the ERK phosphorylation cascade. Mammals express three Raf proteins: A-Raf, B-Raf, and Raf-1, also known as C-Raf. Human Raf-1 contains three distinct regions; an N-terminal RBD (Ras-binding domain) (aa 56 - 131), followed by two rich segments [a cysteine-finger region (aa 138 - 184) (also called CR1/C1) and a second cysteine-rich region (CR2) (aa 253 - 264)] and a C-terminal Ser/Thr kinase catalytic domain (aa 354 - 611). Active Raf-1 phosphorylates and activates the MAPK kinases MEK1 and 2, which in turn phosphorylate and activate the MAP kinases ERK1 and 2.
