This is because the protein and its interactive neighbours may form a protein complex performing a particular function or may be involved in the same pathway.
The four-subunit pol-prim complex performs a unique function in the initial step of DNA synthesis.
In this phase of the autophagy process, the formation of the type III phosphatidylinositol 3-kinase (Ptdlns3K) complex performs a key role in triggering autophagy and its applications in phagophore formation.
The Cyclin B/cdc2 complex performs an important function in controlling the G2/M phase by rapidly phosphorylating the target protein to induce progression into the M phase [ 13, 14].
Several metabolic functions and processes are constantly and concurrently maintained in the liver, which is a complex organ performing a plethora of vital functions [ 15].
The net two decarboxylation events performed on 1 equiv of coproporphyrinogen is a complex reaction performed at a single [4Fe 4S] cluster.
