| 产品介绍 | The protein encoded by this gene belongs to the highly conserved cyclin family, whose members are characterized by a dramatic periodicity in protein abundance through the cell cycle. Cyclins function as regulators of CDK kinases. Different cyclins exhibit distinct expression and degradation patterns which contribute to the temporal coordination of each mitotic event. This cyclin forms a complex with and functions as a regulatory subunit of CDK2, whose activity is required for cell cycle G1/S transition. This protein accumulates at the G1-S phase boundary and is degraded as cells progress through S phase. Overexpression of this gene has been observed in many tumors, which results in chromosome instability, and thus may contribute to tumorigenesis. This protein was found to associate with, and be involved in, the phosphorylation of NPAT protein (nuclear protein mapped to the ATM locus), which participates in cell-cycle regulated histone gene expression and plays a critical role in promoting cell-cycle progression in the absence of pRB. Two alternatively spliced transcript variants of this gene, which encode distinct isoforms, have been described. Two additional splice variants were reported but detailed nucleotide sequence information is not yet available. Transcript Variant: This variant (1) contains a different 5' end region, which includes an upstream in-frame translation start codon, when compared to variant 2. The encoded protein has a 15 aa longer N-terminus, as compared to isoform 2. Subunit: Interacts with a member of the CDK2/CDK protein kinases to form a serine/threonine kinase holoenzyme complex. The cyclin subunit imparts substrate specificity to the complex. Found in a complex with CDK2, CABLES1 and CCNA1 (By similarity). Part of a complex consisting of UHRF2, CDK2 and CCNE1. Interacts directly with UHRF2; the interaction ubiquitinates CCNE1 and appears to occur independently of CCNE1 phosphorylation. Subcellular Location: Nucleus. Tissue Specificity: Highly expressed in testis and placenta. Low levels in bronchial epithelial cells. Post-translational modifications: Phosphorylation of Thr-395 by GSK3 and of Ser-399 by CDK2 accelerates degradation via the ubiquitin proteasome pathway. Phosphorylated upon DNA damage, probably by ATM or ATR. Similarity: Belongs to the cyclin family. Cyclin E subfamily.

文献和实验对照siGFP的细胞获得的数据进行比较。 针对GDF3和DONSON的siRNA都显示在7-AAD细胞周期分析中的作用。 因此，我们期待在细胞周期检测板中分析的一些基因中也观察到表达的变化。 实际上，在将转染siRNA靶向GDF3和DONSON的细胞与转染siGFP的对照细胞相比时，我们发现了25个显示大于50%表达差异的基因（图4）。 在细胞周期检测预制板上的94个基因中，当与siGFP处理的对照细胞相比时，周期素D2在GDF3和DONSON处理的细胞中分别下调70%和85%（图4）。 周期素E2

，但在实际操作中由于需要特殊的设备和安全防护，因此限制了它在实际过程中的广泛应用。1992年，Sano等人以生物素化的抗体取代Sano免疫-PCR系统中的抗体，用商品化的亲和素代替链亲和素-蛋白A嵌合体作为连接分子构建了一个新的免疫-PCR系统。Ruzicka用此免疫-PCR系统检测小鼠抗载脂蛋白E抗体。可以检测出包被浓度为10fg/ml的E抗体。
