Definitions:

Gene Regulatory Network

A gene regulatory network is a collection of molecular regulators that interact with each other and with other substances in the cell to govern the gene expression levels of mRNA and proteins.

Transcription Factor

A transcription factor is a protein that regulates the expression of a gene by binding to a specific DNA sequence in association with the gene sequence. A single transcription factor can regulate many genes if they share the same regulatory sequence.

Cis-regulatory Element

A region of non-coding DNA that regulates the transcription of nearby genes, playing a crucial role in controlling gene expression.

Olfactory Receptor

A type of protein located in the cell membranes of olfactory neurons, involved in the detection of smell molecules.
