Q.. 24. - Biology

Question

Name two important functions of hormone receptors.

Step-by-Step Solution

Answer

• The hormone-receptor complex binds to a sequence of DNA known as a hormone response element (HRE) in the nucleus, triggering gene transcription and translation.
• Changes in cellular function can then be caused by the corresponding protein product.
• Heat shock proteins (HSPs) are so-called because they aid in the folding of folded proteins.

Step 1: Introduction

• A hormone receptor is a molecule that binds to a particular hormone.
• Peptide hormone receptors are typically found on the plasma membrane of cells, whereas lipid-soluble hormone receptors are found in the cytoplasm.

Step 2: Explanation

Hormonal receptors serve two primary functions:

1. The signal's transmission.
2. increasing gene expression.

This interaction enables the hormone receptor to produce a second messenger in the cell to aid in the response. 

Second messengers can also be sent to interact with intracellular receptors, allowing them to enter the signalling system that eventually changes cellular function.
