Find a protein using PDB explorer- describe your protein, including what disease state or other real-world application it has.

The protein I investigated was 1A2K, which is a transport nuclear protein. This protein is made up of alpha helices and beta pleated sheets and is composed of 5 subunits. You can find it in the nucleus and in the cell cytoplasm during mitosis. You can find this protein in Ratus norvegicus and Canis lupus familiaris. This protein facilitates protein transport into the nucleus and RNA transport out of the nucleus. It is involved in chromatin condensation and control of cell cycle.
