Activation of c-Raf is the best understood and involves phosphorylation at mμltiple activating sites, including Ser338, Tyr341, Thr491, Ser494, Ser497, and Ser499. p21-activated kinase (PAK) has been shown to phosphorylate c-Raf at Ser338, and the Src family phosphorylates Tyr341 to induce c-Raf activity. Ser338 of c-Raf corresponds to similar sites in A-Raf (Ser299) and B-Raf (Ser445), although this site is constitutively phosphorylated in B-Raf. Inhibitory 14-3-3 binding sites on c-Raf (Ser259 and Ser621) can be phosphorylated by Akt and AMPK, respectively. While A-Raf, B-Raf, and c-Raf are similar in sequence and function, differential regμlation has been observed. Of particμlar interest, B-Raf contains three consensus Akt phosphorylation sites (Ser364, Ser428, and Thr439) and lacks a site equivalent to Tyr341 of c-Raf. Research studies have shown that the B-Raf mutation V600E resμlts in elevated kinase activity and is commonly found in malignant melanoma. Six residues of c-Raf (Ser29, Ser43, Ser289, Ser296, Ser301, and Ser642) become hyperphosphorylated in a manner consistent with c-Raf inactivation. The hyperphosphorylation of these six sites is dependent on downstream MEK signaling and renders c-Raf unresponsive to subsequent activation events.\u003c\/p\u003e\n\n\u003cp\u003eCategory: Primary Antibody\u003c\/p\u003e\n\n\u003cp\u003eReactivity: Human, Rat, Mouse\u003c\/p\u003e\n\n\u003cp\u003eHost: Rabbit\u003c\/p\u003e\n\n\u003cp\u003eApplications: WB, IF, IP\u003c\/p\u003e\n\n\u003cp\u003eAlternate Names: RAF proto-oncogene serine\/threonine-protein kinase, Proto-oncogene c-RAF, cRaf, Raf-1, RAF1, RAF\u003c\/p\u003e\n\n\u003cp\u003eClonality: Polyclonal\u003c\/p\u003e\n\n\u003cp\u003eConjugate: Unconjugated\u003c\/p\u003e\n\n\u003cp\u003eModification: Phosphorylated\u003c\/p\u003e\n\n\u003cp\u003eImmunogen: Synthetic phosphopeptide derived from human Raf-1 around the phosphorylation site of Serine 621.\u003c\/p\u003e\n\n\u003cp\u003eDilution: WB: 1:1000~1:2000\u003cbr\u003e\nIF: 1:50~1:200\u003cbr\u003e\nIP: 1:50~1:200\u003c\/p\u003e\n\n\u003cp\u003ePurification: The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen and the purity is \u0026gt; 95% (by SDS-PAGE).\u003c\/p\u003e\n\n\u003cp\u003eSpecificity: Raf-1 (Phospho-Ser621) polyclonal antibody detects endogenous levels of Raf-1 protein only when phosphorylated at Ser621.\u003c\/p\u003e\n\n\u003cp\u003eMolecular Weight: ~ 75 kDa\u003c\/p\u003e\n\n\u003cp\u003ePathway: ESC Pluripotency and Differentiation Signaling Pathway, ErbB HER Signaling, G Protein-coupled Receptors Signaling to MAPK Erk, MAPK Erk in Growth and Differentiation Pathway(, Jak Stat: IL-6 Receptor Signaling, Inhibition of Apoptosis, Insμlin \u0026amp;Glucose Signaling, T cell receptor signaling,\u003c\/p\u003e \n\n\u003cp\u003eStorage and Stability: Store at 4°C short term.
