receptor - protein that binds to specific extracellular signaling molecule (ligand) and initiates a response in the cell.
Full article >>>

A receptor protein in the plasma membrane that responds to the binding of a signal molecule by catalyzing the transfer of phosphate groups from ATP to tyrosines on the cytoplasmic side of the receptor.

HIV Receptors
Still one: The two distinct co-receptors on the surface of T cells are CXCR4 and CCR5, both requiring CD4 for the entry of the HIV virus.

Each photoreceptor cell consists of two main sections, the cell body and the rhabdomere. The cell body contains the nucleus while the rhabdomere is made up of toothbrush-like stacks of membrane called microvilli. Each microvillus is 1 mm to 1.

CRP
Catabolite receptor protein, also called CAP or catabolite activator protein. The interaction of CRP with cAMP modulates many aspects of catabolite repression in enteric bacteria.

If I've been at all clear, you'll see that once an animal has different photoreceptor classes the rest of the nervous system is already prepared to take advantage of them. An interesting case study in this regard is new world monkeys.

Apoptosis is often induced by activation of death receptors (DR) belonging to the
tumor
necrosis factor receptor (
TNFR
) family. Examples are
Fas
(CD95), TNFR-1 and
TNFR
-related apoptosis-mediated protein (TRAMP).
