Defect in transport system causes DNA chaos in red blood cells
Within all our cells lies two meters of DNA, highly ordered in a structure of less than 10 micro meters in diameter. Special proteins called histones act as small building bricks, organising our DNA in this structure. Preservation of the structure is necessary to maintain correct function of our genes, making histones detrimental for maintaining a healthy and functional body. The research group of Associate Professor Anja Groth from BRIC, University of Copenhagen, has just elucidated a function of the protein Codanin-1, shedding light on the rare anemic disease CDAI where development of the red blood cells is disturbed. The new results also contribute with important knowledge on how our DNA-structure is maintained and how our genes are regulated.
