產品描述：

The production of this Recombinant Human FBXW7 protein required the insertion of a DNA fragment (FBXW7, 1-707aa) into an expression vector (a plasmid vector) and the transferral of this vector into in vitro E.coli cells (the step of transformation). The cells were then cultured and induced to express the FBXW7 protein. This recombinant protein was fused with N-terminal 6xHis tag. Its purity is 90%+ determined by SDS-PAGE.
FBXW7 functions as the substrate recognition component of the SCF E3 ubiquitin ligase. It is a key tumor suppressor and one of the most frequently deregulated ubiquitin-proteasome system proteins in human cancer. It specifically controls proteasomal degradation of oncoproteins such as cyclin E, c-Myc, Mcl-1, mTOR, Jun, Notch, and AURKA. FBXW7 gene mutations or decreased expression have a crucial biological function in tumor development. FBXW7 is also involved in embryonic development, as well as the proliferation and maturation of stem cell populations.

靶點詳情

功能：

Substrate recognition component of a SCF (SKP1-CUL1-F-box protein) E3 ubiquitin-protein ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of target proteins. Recognizes and binds phosphorylated sites/phosphodegrons within target proteins and thereafter bring them to the SCF complex for ubiquitination. Identified substrates include cyclin-E (CCNE1 or CCNE2), DISC1, JUN, MYC, NOTCH1 released notch intracellular domain (NICD), NFE2L1, NOTCH2, MCL1, and probably PSEN1. Acts as a negative regulator of JNK signaling by binding to phosphorylated JUN and promoting its ubiquitination and subsequent degradation. Involved in bone homeostasis and negative regulation of osteoclast differentiation. Regulates the amplitude of the cyclic expression of hepatic core clock genes and genes involved in lipid and glucose metabolism via ubiquitination and proteasomal degradation of their transcriptional repressor NR1D1; CDK1-dependent phosphorylation of NR1D1 is necessary for SCF(FBXW7)-mediated ubiquitination. Also able to promote 'Lys-63'-linked ubiquitination in response to DNA damage. The SCF(FBXW7) complex facilitates double-strand break repair following phosphorylation by ATM: phosphorylation promotes localization to sites of double-strand breaks and 'Lys-63'-linked ubiquitination of phosphorylated XRCC4, enhancing DNA non-homologous end joining.

13. FBXW7 is markedly downregulated in the liver of obese subjects. A functional low-frequency human FBXW7 coding variant (p.Ala204Thr) is associated with elevated blood glucose and T2DM risk in a Chinese population. Mechanistically, FBXW7 directly binds to hepatokine fetuin-A to induce its ubiquitination and subsequent proteasomal degradation, comprising an important mechanism maintaining glucose homeostasis. PMID: 29475832
14. Our findings suggest FBW7 mutational status and Mcl-1 stability as key determinants of response to Hsp90 inhibitors, which provides a rationale for using FBW7 genotype for potential patient stratification, and for drug combinations with Hsp90 inhibitors that can effectively overcome Mcl-1-mediated resistance.
