| 产品介绍 | background: Heterodimers between TCF3 and tissue-specific basic helix-loop-helix (bHLH) proteins play major roles in determining tissue-specific cell fate during embryogenesis, like muscle or early B-cell differentiation. Dimers bind DNA on E-box motifs: 5'-CANNTG-3'. Binds to the kappa-E2 site in the kappa immunoglobulin gene enhancer. Function: Transcriptional regulator. Involved in the initiation of neuronal differentiation. Heterodimers between TCF3 and tissue-specific basic helix-loop-helix (bHLH) proteins play major roles in determining tissue-specific cell fate during embryogenesis, like muscle or early B-cell differentiation. Dimers bind DNA on E-box motifs: 5'-CANNTG-3'. Binds to the kappa-E2 site in the kappa immunoglobulin gene enhancer. Binds to IEB1 and IEB2, which are short DNA sequences in the insulin gene transcription control region. Subunit: Forms a heterodimer with ASH1 and TWIST2. Isoform E12 interacts with RALGAPA1 and FIGLA. Efficient DNA binding requires dimerization with another bHLH protein. Component of a nuclear TAL-1 complex composed at least of CBFA2T3, LDB1, TAL1 and TCF3. Interacts with NEUROD2, PTF1A and TGFB1I1 (By similarity). Homodimer. Heterodimer. Forms a heterodimer with NEUROD1; the heterodimer is inhibited in presence of ID2, but not NR0B2, to E-box element. Interacts with EP300 and UBE2I. Subcellular Location: Nucleus. Post-translational modifications: Phosphorylated following NGF stimulation (By similarity). DISEASE: Note=Chromosomal aberrations involving TCF3 are cause of forms of pre-B-cell acute lymphoblastic leukemia (B-ALL). Translocation t(1;19)(q23;p13.3) with PBX1. TCF3-PBX1 transforms cells by constitutively activating transcription of genes regulated by PBX1 or by other members of the PBX protein family. Translocation t(17;19)(q22;p13.3) with HLF. Inversion inv(19)(p13;q13) with TFPT. Similarity: Contains 1 bHLH (basic helix-loop-helix) domain.

文献和实验相关实验
采用模型系统进行研究，可以得到对蛋白质的立体化学有贡献的实质性理解。合成多肽为确定与蛋白质的结构和功能有关的构象及相互作用，提供了颇具吸引力的途径。 螺旋结构是蛋白质、核酸、多糖及许多合成多肽的共同结构特征。研究模型多肽在固态和溶液中的螺旋结构，对明确解释在纤维蛋白和球蛋白的构象研究中得出的结论具有重要意义。 多肽是由α氨基酸按下面的通式组成的聚酰胺，其中R是α氨基酸中的侧链： 根据下面的基本假定，Pauling和Corey设想α-螺旋是折叠多肽比较稳定的二级结构之一： 多肽残基是反式共
DNA结合蛋白的共同特性是具有一些与DNA结合的螺旋区，并能形成二聚体。螺旋—环—螺旋(helix-loop-helix，HLH)蛋白质具备上述两种特性，并都有一个共同的基序。基序由40～50个氨基酸组成，含有2个两亲的(amphipathic，既有极性基也有非极性基)。螺旋，由2个长度不等的连接区(环)相连。通过两条螺旋对应位置上的疏水性氨基酸残基之间的相互作用，可以生成同源二聚体或异源二聚体。每个螺旋区长15～16个氨基酸，其中有几个氨基酸残基是保守的。两个螺旋区之间的环使两个螺旋区
的环使两个螺旋区可以彼此独立地相互作用。大部分HLH蛋白的HLH基序旁边都有一段高度碱性的氨基酸序列，这是同DNA 结合所需。在15个氨基酸组成的序列中有6个保守的氨基酸残基，含有这一段氨基酸序列的HLH蛋白质称为bHLH蛋白质。例如，E12和E47两种bHLH蛋白质，结合在免疫球蛋白基因的增强子上；转录因子MYOD和MYF―5参与肌肉生成。bHLH蛋白质可分为两类：一类遍布于各种组织，如哺乳动物的E12／E47和果蝇的da；另一类只存在于某种组织，包括哺乳动物的MYOD和果蝇的AC-S
