A particular fibroblast mutation fails to move to the site of infection.It is discovered that this mutation causes a particular protein to be absent,which leads to premature actin mRNA translation.Which protein is most likely absent due to the mutation?
A)poly- A polymerase
B)CPEB
C)ZBP1 zip code- binding protein
D)general transcription factor
E)Src

ZBP1 (zip code-binding protein) is responsible for localizing actin mRNA to specific sites within the cell. Its absence would lead to premature translation of actin mRNA, preventing proper localization and affecting cell movement.
