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). Src

B). ZBP1 (Zip-code bindinf protein)

C). CPEB

D). General transcription factor

E). Poly-A polymerase

B. ZBP1 (zip code binding protein)

Explanation:

ZBP1 is necessary for the prevention of premature translation, this protein is responsible for the transcription of beta-actin in the nucleus, since it is mutated, the effects will be observed because there will be no movement of fibroblasts to the infection site

the CPEB is false because it has the function of regulating the translation of mRNA, the SCR is not correct because its main role is the activation of protein kinases, thus also ruling out the general transcription factor which is It is responsible for the initiation of transcription in eukaryotes and poly A polymerase is also ruled out because its function is found in the production of poly A tail.
