What proteins are involved in the transition of G0 to G1in the cell cycle? ( I know P53 is one but am having trouble finding the others)
Homework Answers
There are several proteins which are required for the transition of G0 to G1 phase in the cell cycle. G0 phase is also known as quiescent state. Here cells are temporarily in a rest position, preparing for cell division . G1 phase is also known as growth phase of the cell. Enzymes are synthesized for DNA replication at this stage. Here, p53 and Rb gene are the main controlling proteins. In addition to p53 and Rb, there are other proteins too namely p21, p27,p57 which also play a part in the transition phase. Phosphorylation of Rb protein and knockout of p57 and p21 protein is necessary for the cell to exit the G0 phase.

23. The levels of these proteins fluctuate dramatically as cells progress through the cell cycle. These fluctuations are tightly coordinated with the schedule of advances through the various cell cycle phases. For a particular subtype, extracellular signals, notably those conveyed by growth factors, strongly influence their levels. These proteins are: cdc25-like phosphatases b. Cdk kinases c. Protectins d. Cyclins 24. Which of the following best describes the biochemistry that correlates to one of the cell cycle functions of...

1 You are a studying the progression of cells through the cell cycle. You are particularly interested in the cyclins E and A, both of which contribute sequentially to the same cell cycle transition. In this case one cyclin initiates the transition and the other completes the process. In these images you see cell extracts from Hela Cells. A) shows the levels of various proteins, while B) shows the amount of DNA in the cells, more DNA shifts this graph...
