During the G1 phase of the cell cycle, when S phase Cyclin dependent kinase CDK levels are low, ORC recruits Cdc6 and Cdt1. One Cdc6 and one Cdt1 bind to each strand of DNA. Cdc6 and Cdt1 interact with each other and inhibit Mini Chromosome Maintenance Mcm , a DNA helicase that binds after Cdc6 and Cdt1 binding to the ORC. The ORC, Cdc6 , Cdt1 and Mini Chromosome Maintenance Mcm proteins form the Pre replication complex . Activated S CDK triggers S phase and phosphorylates Cdc6 . Phosphorylated Cdc6 is degraded. Cdt1 is inhibited by geminin . With Cdc6 and Cdt1 no longer bound, Mini Chromosome Maintenance Mcm can unwind the double stranded DNA allowing the preinitiation complex to bind. ORC is phosphorylated and DNA replication takes place. DDK also participates in ORC activation and triggers the transition into DNA replication.

distinguish2 PIN1 Pin formed 1 , an auxin transporter in Arabidopsis thaliana Orphan date February 2009 Pin 1 , or peptidyl prolyl cis trans isomerase PPIase , isomerizes only phospho Serine Threonine Proline sequence motif motifs . The enzyme binds to a subset of proteins and thus plays a role as a post phosphorylation control in regulating protein function. Studies have shown that the deregulation of Pin1 may play a pivotal role in various diseases. Notably, the up regulation of Pin1 may be implicated in certain cancers , and the down regulation of Pin1 may be implicated in Alzheimer s disease . Inhibitors of Pin1 may have therapeutic implications for cancer and immune disorders . Discovery and characterization The gene encoding Pin1 was identified in 1996 as a result of a genetic biochemical screen for proteins involved in mitotic regulation . It was found to be essential for cell division in some organisms. By 1999, however, it was apparent that Pin1 knockout mice had a surprisingly mild phenotype , indicating that the enzyme was not required for cell division per se. Further studies later found that loss of Pin1 in mice displays not only neuronal degenerative phenotypes but also several abnormalities, similar to those of cyclin D1 null mice, suggesting the conformation changes mediated by Pin1 may be crucial for cell normal function. Activation of Pin1 Phosphorylation of Ser Thr Pro motifs in substrates is required for recognition by Pin1. Pin is a small protein at 18 kDa and does not have a nuclear localization or export signal. Substrate interactions and a WW domain determine subcellular distribution. Expression is induced by growth signals from E2F transcription factors. Expression levels fluctuate in normal, but not in cancerous cells. Expression is often associated with cell proliferation . Postranslational modifications such as phosphorylation on Ser16 inhibit the ability of Pin1 to bind substrate, and this inhibitory process may be altered during oncogen ... more details

Additional, newly identified LPA receptors include LPA4 p2y9 GPR23 , LPA5 GPR92 and LPA6 GPR87 . Clinical significance Because of its ability to stimulate cell proliferation , aberrant LPA signaling has been linked to cancer in numerous ways. Dysregulation of autotaxin or the LPA receptors can lead to hyperproliferation, which may contribute to oncogenesis and metastasis . LPA may be the cause pruritus itching in individuals with cholestatic impaired bile flow diseases. GTPase activation Downstream of LPA receptor activation, the small GTPase Rho can be activated, subsequently activating Rho kinase. This can lead to the formation of stress fibers and cell migration through the inhibition of myosin light chain phosphatase .

As with all retroviruses, it reverse transcribes its RNA genome into cDNA before integration into the host DNA. History RSV was discovered in 1911 by Peyton Rous , working at Rockefeller University in New York City, by injecting cell free extract of chicken tumour into healthy Plymouth Rock chickens. The extract was found to induce oncogenesis . The tumour was found to be composed of connective tissue a sarcoma . Rous was awarded the Nobel Prize for the significance of his discovery in 1966 . Structure and genome RSV is a class VI enveloped virus with a positive sense RNA genome having a DNA intermediate. RSV has three genes gag gene gag encodes capsid proteins pol gene pol encodes reverse transcriptase It lost the env gene normally seen in avian retroviruses during the recombination events that allowed it to acquire src src gene src encodes a tyrosine kinase that attaches phosphate groups to the amino acid tyrosine in host cell proteins. The RSV genome has terminal repeat s enabling its integration into the host genome and also overexpression of RSV genes. src gene The Src gene src gene is oncogene oncogenic as it triggers uncontrolled growth in abnormal host cells. It is an acquired gene, found to be present throughout the animal kingdom with high levels of conservation between species. The src gene was taken up by RSV and incorporated into its genome conferring it with the advantage of being able to stimulate uncontrolled mitosis of host cells, providing abundant cells for fresh infection . The src gene is not essential for RSV proliferation but it greatly increases virulence when present. RNA secondary structure Image RSV secondary structure.jpg thumb 2 ... more details
