CI Immunity Repressor Protein

These flashcards cover key concepts and definitions related to the CI Immunity Repressor Protein and its role in phage biology.

Immunity Repressor Protein

A DNA binding protein that maintains phage lysogeny and represses gene transcription.

CI repressor protein

Prevents the phage from lysogenizing, allowing the host to survive, by binding to specific DNA sequences.

Autoregulation

The ability of the CI repressor protein to regulate its own expression.

Immunity region

The genome coding region associated with the CI repressor protein.

Transcriptional repressor

The role of the CI repressor protein in preventing the replication of viral DNA.

Operator sites

Specific regions on the DNA where the CI protein binds to make the phage dormant and immune to infection.

Lysogenic circuit

A multilevel regulatory system involving the CI repressor protein that controls lysogeny.

Dual functionality

The characteristic of the CI repressor protein that allows it to have both positive and negative regulatory outcomes.

Molecular regulators

Tiny yet powerful proteins like the CI repressor that play critical roles in cellular processes.
