Receptor proteins are designed so special molecules can bind to them, and send messages to the cell that trigger some sort of reaction within the cell.
They are embedded in either the plasma membrane or cytoplasm of a cell, to which a mobile signaling (or "signal") molecule may attach.

What else can I help you with?
Are receptor proteins membrane proteins or are they found in other cellular compartments?
Receptor proteins are typically membrane proteins, meaning they are located on the cell membrane.
A protein on the cell membrane binds and recognized to specific substance is called a?
It is called a receptor protein.
What would be least affected by defective receptor proteins on a cell membrane?
The transport of nutrients and waste across the cell membrane would be least affected by defective receptor proteins. This is because transport proteins, not receptor proteins, are primarily responsible for moving molecules across the cell membrane.
How do receptor tyrosine kinases function within cellular signaling pathways?
Receptor tyrosine kinases are proteins on the cell surface that receive signals from outside the cell and activate a series of chemical reactions inside the cell. When a signaling molecule binds to the receptor, it triggers the receptor to add phosphate groups to specific tyrosine residues on itself and other proteins, leading to the activation of various signaling pathways that regulate cell growth, division, and survival.
What binds to a signal molecule enabling the cell to respond to the signal molecule?
A receptor protein on the cell membrane binds to the signal molecule, initiating a series of intracellular events that lead to a cellular response. The binding of the signal molecule to the receptor triggers a signaling cascade that ultimately activates specific cellular pathways.
What is the function of a receptor?
Receptor proteins are used to pass messages between cells. They send the messages from outside of the cell to the inside of the cell.
In a cell Which function is NOT accomplished by receptor proteins?
Receptor proteins do not typically carry out functions such as cell metabolism, protein synthesis, or DNA replication. Their main function is to receive and transmit signals from the extracellular environment to the inside of the cell.
What type of membrane proteins allow cells to identify one another?
Receptor proteins.
Each lymphocyte has thousands of receptor proteins in its membranes. What is the job of these receptor proteins?
To recognize antigens.
Are receptor proteins membrane proteins or are they found in other cellular compartments?
Receptor proteins are typically membrane proteins, meaning they are located on the cell membrane.
Most receptor proteins are embedded in the?
Receptor proteins are embedded in the lipid bilayer of the cell membrane.
Each lymphocyte has thousands of receptor in its membranes What is the job of these receptor proteins?
To recognize antigens.
A protein on the cell membrane binds and recognized to specific substance is called a?
It is called a receptor protein.
Where are receptor proteins found?
In the cell membrane.
What would be least affected by defective receptor proteins on a cell membrane?
The transport of nutrients and waste across the cell membrane would be least affected by defective receptor proteins. This is because transport proteins, not receptor proteins, are primarily responsible for moving molecules across the cell membrane.
How have humans altered receptor proteins?
They changed the amino acid sequence of the proteins.
What is the job of the receptor proteins?
The job of a receptor protein is to receive chemical signals from outside the cell.
