Some transcription factors, such as leucine zipper proteins, form homodimers or heterodimers. How does this increase the complexity of available strategies of gene regulation?

Transcription Factors

Proteins that bind to specific DNA sequences, thereby controlling the transfer (transcription) of genetic information from DNA to messenger RNA.

Leucine Zipper Proteins

A type of protein that contains a specific motif which allows it to dimerize and bind DNA, playing key roles in regulating gene expression.

Homodimers

Molecular complexes formed from two identical protein molecules that bind together, often to become functionally active.
