Once released, BNP binds to and activates the atrial natriuretic factor receptor NPRA, and to a lesser extent NPRB, in a fashion similar to atrial natriuretic peptide (ANP) but with 10-fold lower affinity.
The GTP layer for the control plane (GTP-C) tunnels signaling messages between GSNs in the GPRS backbone network.The GTP-C enables several procedures to be performed through the GPRS backbone network, including path management, tunnel management, location management, and mobility management.he GTP layer for the control plane (GTP-C) tunnels signaling messages between GSNs in the GPRS backbone network.
1 Cell signaling: Many proteins located on the periphery of the cell membrane are used to initiate cell signaling events in the cell. 2  Cell signalling is the way cells talk to each other or to themselves. 3  The phospholipases are a family of peripheral membrane proteins that release fatty acids from the membrane.
