The c-myc protein is associated with the nuclear matrix through specific metal interaction.
Van Straaten JP., Rabbitts TH.
We have investigated the subnuclear localisation of the protein product of the c-myc oncogene. We show that, although c-myc is not present in the nuclear skeleton or matrix II fraction, it is associated with the nuclear matrix I fraction which is a complex group of proteins implicated in physiological processes within the nucleus. The interaction of the c-myc protein and the matrix I fraction is through a specific metal interaction and presumably, therefore, represents the in vivo location of this protein.
