产品介绍 Cyclin E is a regulatory subunit of Cdk2 and controls G1 / S transition during the mammalian cell cycle. Multiple isoforms of Cyclin E are only expressed in tumors but not in normal tissue, suggesting a post transcriptional regulation of Cyclin E. In vitro analyses indicated that these truncated variant isoforms of Cyclin E are able to phosphorylate histone H1. Alterations in the Cyclin E protein have been implicated as indicators of worse prognosis in various cancers.
Function : Essential for the control of the cell cycle at the G1/S (start) transition.
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.
细胞周期素E是调控细胞G-1→S期转变的关键因素。由于在多种肿瘤中的不适当表达,细胞周期素E现在已明确为原癌基因。
