Answer:
Phosphorylation within the nuclear export signal interferes with the function of the  signal.
Explanation:
In biochemistry, phosphorylation is the addition of a phosphate group (PO4) to a protein or other molecule. Phosphorylation is a major player in protein regulation mechanisms, preventing protein-catalyzed reaction product from accumulating in the body causing problems.
However, in some cases phosphorylation may cause nuclear accumulation of a protein in the nucleus of the cell. An example of this is the protein shown in the question above. In this case, phosphorylation in the nuclear export signal interferes with the signal function, resulting in protein accumulation in the nucleus.

Its interphase i think : 
The meaning of Interphase is : the period of the cell cycle during which the nucleus is not undergoingdivision, typically occurring between mitotic or meiotic <span>divisions.</span>
