Definitions:

Activator Proteins

Proteins that bind to specific DNA sequences, thereby increasing the rate of transcription of genes, playing a crucial role in regulating gene expression.

Transcription Factors

Proteins that regulate the transcription of genes by binding to specific DNA sequences, influencing the rate at which genetic information is copied to mRNA.

Enhancer

A segment of DNA that can increase the rate of transcription of genes, often located far from the gene it regulates.

Leucine Zipper Proteins

A type of protein that plays a role in regulating gene expression by forming a zipper-like structure that facilitates DNA binding.
