产品介绍background:
FOXO4 is a forkhead transcription factor involved in the regulation of the insulin signaling pathway. It binds to insulin-response elements (IREs) and can activate transcription of IGFBP1. FOXO4 down-regulates expression of HIF1A and suppresses hypoxia-induced transcriptional activation of HIF1A-modulated genes. It is also involved in negative regulation of the cell cycle.
Function:
Transcription factor involved in the regulation of the insulin signaling pathway. Binds to insulin-response elements (IREs) and can activate transcription of IGFBP1. Down-regulates expression of HIF1A and suppresses hypoxia-induced transcriptional activation of HIF1A-modulated genes. Also involved in negative regulation of the cell cycle.
Subunit:
Interacts with CREBBP/CBP, CTNNB1, MYOCD, SIRT1, SRF and YWHAZ. Acetylated by CREBBP/CBP and deacetylated by SIRT1. Binding of YWHAZ inhibits DNA-binding. Interacts with USP7; the interaction is enhanced in presence of hydrogen peroxide and occurs independently of TP53. Interacts with NLK, and this inhibits monoubiquitination and transcriptional activity.
Subcellular Location:
Cytoplasm. Nucleus. When phosphorylated, translocated from nucleus to cytoplasm. Dephosphorylation triggers nuclear translocation. Monoubiquitination increases nuclear localization. When deubiquitinated, translocated from nucleus to cytoplasm.
Tissue Specificity:
Heart, brain, placenta, lung, liver, skeletal muscle, kidney and pancreas. Isoform zeta is most abundant in the liver, kidney, and pancreas.
Post-translational modifications:
Acetylation by CBP, which is induced by peroxidase stress, inhibits transcriptional activity. Deacetylation by SIRT1 is NAD-dependent and stimulates transcriptional activity. Phosphorylation by PKB/AKT1 inhibits transcriptional activity and is responsible for cytoplasmic localization.
DISEASE:
Note=A chromosomal aberration involving FOXO4 is found in acute leukemias. Translocation t(X;11)(q13;q23) with MLL/HRX. The result is a rogue activator protein.
Similarity:
Contains 1 fork-head DNA-binding domain.

phospho-FOXO4 (Thr451)抗体(antibody,
Ab)是由效应B细胞(效应**B细胞)分泌,机体用于抵御外来物质,如病毒,**等抗原,结构呈“Y”字型的球状蛋白质,仅仅存在于脊椎动物的血液和B**细胞膜表面。凡是能够跟抗体结合的物质,均被称作抗原,因此对于抗抗体(能够结合抗体的抗体)来说,抗体本身也是一种抗原物质。
phospho-FOXO4 (Thr451)抗体普通抗体重链和轻链的结构
重链结构:普通的**球蛋白具有2条重链(H链),分子量约为50kD,有μ、δ、γ、ε和α五种重链亚型,对应的**球蛋白名称分别为IgM、IgG、IgA、IgD和IgE。
轻链结构: 普通**球蛋白具有2条轻链(L链),分子质量约25kDa,有κ链和λ链两种亚型,这两种轻链决定了Ig的亚型类别(IgG1,IgG2,IgG3,IgG4)。一个天然的Ig分子两条轻链总是相同的,但在同一个体内可存在分别带有κ或λ链的抗体分子。不同种属生物体内两型轻链的比例不同,正常人血清**球蛋白κ链:λ链约为2:1,而在小鼠的比例为20:1。
2.2抗体Fab段和Fc段
IgG经木瓜蛋白酶酶切后裂解为2个完全相同的Fab段和1个Fc段,每个Fab段都为单价,可与抗原结合但不会再发生凝集反应;经胃蛋白酶酶切后裂解为1个完整F(ab)2片段和碎片化的Fc片段,F(ab’)2片段为双价,可同时结合两个抗原表位。Fab段为抗原结合片段(fragment of antigen binding,Fab),相当于抗体分子的两个臂,由一个完整的轻链和重链的VH和CH1结构域组成。Fc段为可结晶段(fragment crystallizable,Fc)相当于Ig的CH2和CH3结构域,是Ig与效应分子或者细胞相互作用的部位。Fab段包含完整的可变区,以及恒定区的CH1区域。Fc段仅指Ig恒定区CH2和CH3的区域,相当于Y字结构下面那一部分。
