Stretch of amino acids near c terminal

You genetically engineer nucleoplasmin so that a stretch of amino acids near its C-terminal end (called the NLS) is removed. What happens to the resultant nucleoplasmin protein if this altered gene is transfected into an amphibian oocyte and transcribed into mRNA, which is then translated? If you were to alter the NLS of a particular nuclear protein by replacing the codon for a basic amino acid in its NLS with a codon coding for a nonpolar amino acid, what would happen if this altered gene were transfected into an amphibian oocyte and transcribed into mRNA, which is then translated? If you were to fuse an NLS to a well-known non-nuclear protein (serum albumin) and inject it into the cytoplasm of the cell, what would happen?
