The repressor protein is coded by the i gene.
A protein known as a repressor prevents one or more genes from being expressed. The i gene codes for the repressor protein. The repressor protein inhibits messenger RNA synthesis by attaching to the promoter region of the gene(s). For the control of gene expression in cells, repressor proteins are crucial.
Repressors and activators of gene expression in bacteria are different from one another. However, depending on how a DNA binding protein interacts with other proteins in the cell or in other biological contexts, higher eukaryotic cells can use it as either an activator or a repressor of gene expression. As repressors, additional components like non-coding RNA may also be present.
