If we are to based it in the function of a testosterone inside a cell, it does not act as a signal receptor. Testosterone function is to bind a receptor protein that go into the nucleus and to activate a particular gene.
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.
Receptor proteins are typically membrane proteins, meaning they are located on the cell membrane.
Epinephrine binds to its receptor on the cell membrane, activating the G protein coupled receptor. This leads to activation of adenylyl cyclase, which produces cyclic AMP (cAMP). cAMP activates protein kinase A, which phosphorylates target proteins to carry out the cellular response, such as glycogen breakdown in muscle cells.
The five types of integral proteins are channels, carriers, pumps, receptors, and enzymes. These proteins are embedded within the cell membrane and play vital roles in transporting molecules across the membrane, sensing signals from the environment, and catalyzing chemical reactions.
It is called a receptor protein.

Receptor proteins.
Receptor proteins are specialized proteins that bind specific molecules, such as hormones or neurotransmitters, triggering a cellular response. Carrier proteins, on the other hand, are involved in transport processes, helping to move molecules across cellular membranes. While receptor proteins facilitate communication and signaling within the cell, carrier proteins play a more functional role in transporting molecules.
To recognize antigens.
Receptor proteins are typically membrane proteins, meaning they are located on the cell membrane.
The outer part of a G protein-coupled receptor (GPCR) binds to ligands, such as hormones or neurotransmitters, which activates the receptor. The inner part of the receptor interacts with and activates a G protein, initiating downstream signaling cascades within the cell.
Receptor proteins are embedded in the lipid bilayer of the cell membrane.
Testosterone functions inside a cell by binding to specific receptors in the cytoplasm or nucleus of the cell. This binding activates these receptors, allowing them to enter the nucleus and regulate the expression of specific genes involved in various physiological processes such as muscle growth, bone density, and sperm production.
A transmitter activates a receptor on the cells surface. That receptor, once activated then activates the second messanger inside the cell. That way large molecules can provoke an effect within a cell without actually entering it.
Epinephrine binds to its receptor on the cell membrane, activating the G protein coupled receptor. This leads to activation of adenylyl cyclase, which produces cyclic AMP (cAMP). cAMP activates protein kinase A, which phosphorylates target proteins to carry out the cellular response, such as glycogen breakdown in muscle cells.
