A researcher was studying a protein ‘A’ which has been observed to move across cells when an extracellular electrical stimulus is provided. An artificial peptide ‘Z’ was prepared which resembles the structure of pannexins and competitively inhibits pannexon formation. Which one of the following statements will best explain the fate of protein ‘A’ if, the cells are treated with peptide ‘Z’ and then, electrical stimulus is provided.

  2. A fails to move across cells due to improper formation of gap junctions.

  3. A fails to move across cells due to improper formation of adherens junctions.

  4. A fails to move across cells due to improper formation of desmosomes.
