Cellular Response

Definition

Cellular response refers to any change or action that occurs inside a cell as a result of receiving an external signal through signal transduction. These responses can include changes in gene expression, alterations in enzyme activity, cytoskeletal rearrangements, or even cell death.

Related terms

Effector Proteins: Effector proteins are molecules or enzymes within the cell that directly carry out the specific cellular response once they are activated by a signal transduction pathway.

Transcription Factors:

Transcription factors are proteins that bind to DNA and regulate gene expression. They play a crucial role in determining which genes will be turned "on" or "off" in response to signaling events.

Apoptosis:

Apoptosis, also known as programmed cell death, is a controlled and regulated process where cells undergo self-destruction. It is an essential cellular response for eliminating damaged or unnecessary cells during development or in response to stress signals.
