C3a is one of the proteins formed by the cleavage of complement component 3; the other is C3b. C3a is a 77 residue anaphylatoxin that binds to the C3a receptor (C3aR), a class A G protein-coupled receptor. It plays a large role in the immune response. C3a molecules induce responses through the GPCR C3a receptor. Like other … WebThrough their serine-protease activity, the C3 convertases are capable to cleave the C3 molecule nearby into its bioactive form C3b and C3a, an anaphylatoxin. The generated C3b covalently binds to an activating surface (pathogens, necrotic/apoptotic cells) and forms new C3bBb convertases allowing the self-amplification of the C3 cleavage in a ... kita info app download https://the-traf.com
