Name two important functions of hormone receptors.

Expert verified

The hormone receptor interacts with several molecules to cause a range of changes, including an increase or decrease in the availability of nutrients, growth, and other metabolic processes.
These signalling pathways are intricate systems that work through feedback loops where one signal can both activate and inhibit another.

Hormone receptor proteins bind to a hormone as a results of an accumulation of weak interactions.
Due to the relatively large size of enzymes and receptors, the big amount of extent provides the idea for these weak interactions to occur.
This binding is truly highly specific due to the complementarity of those interactions between polar, non-polar, charged, neutral, hydrophilic, or hydrophobic residues.

Upon binding, the receptor often undergoes a conformational change and should bind further, signaling ligands to activate a signaling pathway.
Due to these highly specific and high affinity interactions between hormones and their receptors, very low concentrations of hormone can produce significant cellular response.

Receptors can have various different structures betting on the function of the hormone and therefore the structure of its ligand.
Therefore, hormone binding to its receptor could be a complex process which will be mediated by cooperative binding, reversible and irreversible interactions, and multiple binding sites.
