Colicin Ia is a type of Colicin, a bacteriocin made by E. coli which acts against other nearby E. coli to kill them by forming a pore in the membrane, leading to depolarisation of the membrane which kills the cell.

The operon for colicin Ib is encoded on a plasmid in the cytoplasm of the E. coli. This operon also encodes its Colicin Immunity Protein, to protect the membrane of the cell from the pore forming activities of the colicin, alongside a protein to aid the release of the colicin outside the cell.
Once produced, the immunity protein inserts into the membrane to prevent pore formation.
