myb-dna-bind怎么分类网友 1 最佳答案 回答者:网友 MYB转录因子以保守的DNA结合域为共同特征,是植物最大的转录因子家族之一,广泛参与植物代谢调控。本文根据植物中MYB转录因子的DNA保守结构域,通过RT-PCR和RACE的方法从大豆品种吉林3号的叶片中分离得到了2个MYB基因GmMYBJ6和GmMYBJ7,并对其结构特征和表达特性进行...
2.1 MYB与上下游因子互作 MYB 主要通过直接结合下游靶基因启动子区域特定的 DNA 序列来激活或抑制其转录. 拟南芥 AtMYB73 直接结合在肌动蛋白解聚因子 (actin-depolymerizing factors, ADF)基因的启动子区 域, 抑制其表达, 阻碍肌动蛋白解聚, 从而改变植物细胞骨架组成[27]. 水稻 OsMYB30 通过激活 OsPAL6 和 ...
One of these, an AACA motif, has been shown to be a negative regulator in non-seed tissues and has a similarity to the barley gibberellin responsive element recognized by MYB-like DNA binding proteins. A cDNA library constructed from immature rice seed was screened using two types of myb ...
This review will focus on v-Myband its normal cellular counterpart c-Mybwith an emphasis on the biological and biochemical functions of their protein products. Both the v-Myb and c-Myb proteins are nuclear, bind directly to DNA, have short half-lives, and can regulate gene expression. As ...
a pathogen-induced DNA-bind- MYB homologs in drought- and abscisic acid-regulated ing protein involved in the plant defense response, Plant J., 4 gene expression, Plant Cell, 9(10):1859-1868 (1): 125-135 Aharoni A., de Vos R.C.H., Wein M., Sun Z., Greco R., Kroon A., Du...
c-MYC activates a variety of known target genes as part of a heterodimeric complex with its partner protein, MAX. MYC–MAX heterodimers bind specific DNA sequences, such as the E-box sequence CACGTG[10]. The 150 amino acid N-terminal region of c-MYC contains two highly conserved elements...
一个是位于 N 端的高度保守的 DNA 结合 域,另一个是位于 C 端的负责调节蛋白质活 性的调节区域.根据结构域所含 R 结构的数 量,植物中的 MYB 转录因子可分为 4 类,分 别是 1R-MYB/MYB-related(1 个 R 结构), R2R3-MYB(2 个 R 结构),R1R2R3-MYB 蛋白(3 个 R 结构)和 4R-MYB(4 个 R ...
In broad outline, cells express receptors that bind growth factors. On binding its ligand, the receptor signals the cell to synthesize DNA and divide. This signal is often transmitted by means of a phosphorylation cascade by which transcription factors are activated. The activated transcription ...
