| 产品介绍 | background: This gene encodes a member of a family of transcription factors that heterodimerize with E2F proteins to enhance their DNA-binding activity and promote transcription from E2F target genes. The encoded protein functions as part of this complex to control the transcriptional activity of numerous genes involved in cell cycle progression from G1 to S phase. Alternative splicing results in multiple transcript variants. Pseudogenes of this gene are found on chromosomes 1, 15, and X.[provided by RefSeq, Jan 2009] Function: The DP2/E2F complex functions in the control of cell-cycle progression from G1 to S phase. The E2F-1/DP complex appears to mediate both cell proliferation and apoptosis. Subunit: Component of the E2F/DP transcription factor complex. Forms heterodimers with E2F family members. The complex can interact with hypophosphorylated retinoblastoma protein RB1 and related proteins (RBL1 and RBL2) that inhibit the E2F transactivation domain. This repression involves recruitment of histone deacetylase (HDAC). During the cell cycle, from mid-to-late G1 phase, RB family members become phosphorylated, detach from the DRTF1/E2F complex to render E2F transcriptionally active. Viral oncoproteins, notably E1A, T-antigen and HPV E7, are capable of sequestering RB protein, thus releasing the active complex. Part of the E2F6.com-1 complex in G0 phase is composed of E2F6, MGA, MAX, TFDP1, CBX3, BAT8, EUHMTASE1, RING1, RNF2, MBLR, L3MBTL2 YAF2. Component of the DREAM complex (also named LINC complex) at least composed of E2F4, E2F5, LIN9, LIN37, LIN52, LIN54, MYBL1, MYBL2, RBL1, RBL2, RBBP4, TFDP1 and TFDP2. The complex exists in quiescent cells where it represses cell cycle-dependent genes. It dissociates in S phase when LIN9, LIN37, LIN52 and LIN54 form a subcomplex that binds to MYBL2. Subcellular Location: Nucleus. Tissue Specificity: Highest levels in muscle. Also expressed in brain, placenta, liver and kidney. Lower levels in lung and pancreas. Post-translational modifications: Phosphorylation by E2F-1-bound cyclin A-CDK2, in the S phase, inhibits E2F-mediated DNA binding and transactivation. Similarity: Belongs to the E2F/DP family.

文献和实验HPV 并不是宫颈癌唯一的「元凶」？这种微生物化身「帮凶」，共同促进癌症发生
修复通路 由于 E2F 转录因子家族（参与细胞增殖和生长停滞的几个基因的重要调节因子）被沙眼衣原体和共感染下调，研究人员进一步分析了 E2F 转录因子家族在衣原体感染细胞中发挥的作用。 RB 样、E2F4、多种外阴 B 类蛋白和二聚化伴侣（DP1）通过形成 DREAM 复合物，可介导基因抑制促进静止。若失去细胞周期检查点基因表达，DREAM 复合物介导的调控将会中断，进而打破细胞周期的平衡，从静止切换到增殖，这在癌症中经常观察到。 该研究分析显示，许多 DREAM 复合靶基因被衣原体下调，在合并感染中
的酵母菌株在缺乏尿嘧啶的选择性培养基上只有当“ 诱饵” 和“ 猎物” 相互作用激活URA3 基因的表达才能生长。在含有5-FOA 的完全培养基上“ 诱饵” 和“ 猎物” 的相互作用则抑制细胞的生长。然而如果目的蛋白，即与DB 或AD 融合的蛋白质发生了突变或者由于外加药物的干扰不再相互作用，URA3 基因不表达，则细胞能在含有5-FOA 的完全培养基上生长。通过这种方法，Vidal 等人筛选到了转录因子E2F1 的突变物，这些突变物仍然能结合视网膜母细胞瘤蛋白RB，但是丧失了同另外一种称为DP1
基因表达调控的重点。现在的基因数据库信息丰富，拿到基因及其启动子序列非常简单。那么问题又来了，拿到启动子序列以后，下一步怎么找相关的调控蛋白/转录因子呢？生物信息学方法预测？你会得到很多可能的目标调控蛋白/转录因子，还要做实验一个一个验证。凝胶迁移（EMSA），染色质免疫共沉淀（ChIP）？只能针对已知能与启动子结合的调控蛋白/转录因子，而且还需要相应探针/抗体，对于大量筛选无能为力。美国Signosis的转录因子(结合启动子)微孔板芯片检测试剂可以方便、高效地解决这一问题。该方法专门用于筛查与特定DNA序列
