Antibodies and signaling pathways

While the signal transduction is often amplified at the same time the signal by an activated protein molecule in turn can activate multiple effectors molecules. For example, one activated by a photon Rhodopsin molecule (the photoreceptors in the retina, vision is responsible for the turn) up to 2000 Transducin molecules. Particular importance is attached to the second messengers, are the secondary messengers of cell metabolism. Known examples are cyclic adenosine monophosphate (cAMP), cyclic guanosine monophosphate (cGMP), Inositol triphosphate (IP3), diacylglycerol (DAG) and calcium ions (Ca2 +). They represent intermediate signal transduction and may in turn activate various signaling pathways. They are therefore suitable as interfaces for different signal transduction pathways and play in the exploration of signal transduction a major role. The many signal transduction pathways are interlinked with antibodies and in addition to cell-specific responses. Cytosolic receptors, such as the steroid receptors, retinoid, and the soluble guanylyl cyclase, the primary targets of steroids, retinoid and small, soluble gases such as nitric oxide (NO) and carbon monoxide (CO), which happen due to their lipophilicity and their low molecular size the cell membrane can. Activation of steroid receptors, for example, leads to the formation of a receptor for that act by binding to a response element, such as sterol response element (SRE) on the DNA itself as transcription factors.
