摘要:

Nucleolar protein B23 can shuttle between the nucleolus and cytoplasm. However, the mechanism involved in the protein moving and staying in the nucleolus is not fully understood. To identify the nucleolar localization signal sequence of protein B23, we examined the subnuclear location of B23.1 mutant proteins fused with green fluorescent protein in HeLa cells. The results suggested that the two C-terminal tryptophan residues (Trp-286 and Trp-288) of protein B23.1 were important in this phenomenon.
