The binding of insulin is communicated through the single TM helix of each beta subunit to the paired Tyr kinase domains inside the cell, activating them to phosphorylate each other on three Tyr residues (Tyr1158, Tyr1162, Tyr1163)

Berger-Parker complement index is that it is very easy to compute. Values of D_BPC vary from 0 to 1.
D_BPC =1 - D_BP
