When phagocytes come into contact with bacteria, the receptors on the phagocyte's surface will bind to them.

These receptors bind to the Fc portion of IgG antibodies.

These receptors can bind different ligands like acetylcholine, nicotine and cobratoxin.

Nuclear receptors bind to coactivators in a ligand-dependent manner.

In contrast, immunohistochemistry or flow cytometry have the advantage of molecular identification, but can not show definitively if the receptors bind ligands.

These receptors are predominately expressed in cells of the immune system and bind ligands such as CD55.

The sequence is most commonly a pair of inverted repeats separated by three nucleotides, which also indicates that the receptor binds as a dimer.

In the absence of TonB, these receptors bind their substrates but do not carry out active transport.

Also the receptor could not bind to antibodies.

These receptors may bind attractants or repellents directly or indirectly through interaction with proteins of periplasmatic space.
