It is clear that WBSCR<strong>22</strong> protein localizes in the nucleus but nobody has demonstrated that the predicted NLS at C-terminus of WBSCR<strong>22</strong> protein is functional. Based on my study, I found that C-terminal domain is needed for nuclear transport giving free road to do further experiments, such as mutating NLS sequence and studying the effect of such mutations on the protein localization. It would also be interesting to fuse WBSCR<strong>22</strong> NLS to the terminus of an unrelated protein, such as GFP, to see if the sequence is sufficient to target the protein to the nucleus. The final goal would be to determine the transport machinery that is involved in the transport of WBSCR<strong>22</strong> to the cell nucleus, which would further help to elucidate WBSCR<strong>22</strong> functions and possibly its role in the development of disease in humans. 26
