Fbxo7 gets proactive with cyclin D/cdk6.
Although all three D cyclins bind and activate cdks 2, 4 and 6, Fbxo7 has been characterised as a selective enhancer of cdk6 activity. It increases activation by directly facilitating cdk6 interaction with viral and cellular D cyclins. Fbxo7 overexpression has transforming activity in murine fibroblasts, and it is also highly expressed in human cancers, suggesting it is a potential oncogene. Fb...
متن کاملTransforming activity of Fbxo7 is mediated specifically through regulation of cyclin D/cdk6.
D cyclins (D1, D2 and D3) and their catalytic subunits (cyclin-dependent kinases cdk4 and cdk6) have a facilitating, but nonessential, role in cell cycle entry. Tissue-specific functions for D-type cyclins and cdks have been reported; however, the biochemical properties of these kinases are indistinguishable. We report that an F box protein, Fbxo7, interacted with cellular and viral D cyclins a...

متن کاملProactive Vulnerability Assessments with Nessus
Proactive Vulnerability Assessments with Nessus The goal of this paper is to illustrate the benefits of deploying Nessus as a low-cost vulnerability scanner as a supplement to an existing security model. I'll discuss vulnerability scanning in general, what Nessus is all about, how to begin scanning your network, and finally why a vulnerability scanner is an essential component of an effective s...
