In order to maintain the fidelity of the developing organism this process of cell division must be highly ordered and tightly regulated. Actually we know some proteins who intervens in the process like P53, but thanks to different investigations we have known other proteins who could take part at the process or could be the same proteins with different functions. The important part is if during cell cycle the cell loss control will lead to abnormal development and is the cause of different diseases like cancer.

7. GENE ACTIVITY REGULATED BY HISTONE H1 THROUGHOUT THE CELL CYCLE Histone H1 is very important in stabilizing chromatin higher-order structures, is called a "linker" histone because it binds the DNA between nucleosomes. Histones are proteins termed H1, H2A, H2B, H3, and H4 JULIO 26 DE 2010 MEDELLIN, COLOMBIA NEW ROLE FOR THE JNK PROTEIN AND GENE ACTIVITY REGULATED BY HISTONE H1 MEDICAL UTILITY This investigation allow see the importance of knowledge about the different functions of proteins in the human body, especially in cell cycle, besides this findings incite us to investigate more about proteins in cell cycle and orient it to prevent different diseases like cancer.

8. GENE ACTIVITY REGULATED BY HISTONE H1 THROUGHOUT THE CELL CYCLE Two each of the histones H2A, H2B, H3, and H4 come together to form a histone octamer, which binds and DNA. The H1 protein is a link. The nine histone proteins and 166 pairs of DNA form a nucleosome . H1 proteins interact with each other, causing the chromatin to form a spiral, with 6 nucleosomes, this is known as a solenoid. DNA is packaged with protein into chromosomes allowing a large amount of DNA to fit in a cell's nucleus.

9. GENE ACTIVITY REGULATED BY HISTONE H1 THROUGHOUT THE CELL CYCLE Phosphorylation is the addition of a phosphate group. Normally we know that the H1 histone is only a clamp protein on nucleosome, but some investigators have finded that the H1 has been phosphorilared and has been associated with changes in gene activity around it.

13. NEW ROLE FOR THE JNK PROTEIN: LONG KNOWN TO HELP CELLS RESPOND TO STRESS, JNK ALSO CONTROLS CELL CYCLE The fidelity of cell reproduction also depends on regulatory mechanisms that ensure that the events of the cell cycle occur in the correct order. To ensure the correct order of events, the cell contains a complex regulatory network called the cell cycle control system, that controls their timing and coordination. The regular check points in the cell are between stage G1 and S, between stage S and G2 and between stage G2 and M.
