Figure 4 From: Broadening the horizon – level 2.5 of the HUPO-PSI format for molecular interactions Assembly of a mature complex (I2) from two protein components (P1 and P2) that bind to form an intermediate assembly (I1) with which a third protein (P3) interacts. I1 is both the result of an interaction and a subsequent interactor in the PSI-MI2.5 format.Back to article page
