Formation of nonameric complex (R-HSA-2213241) [Homo sapiens]

Reaction
Summation

Progressive addition of two more preformed alpha beta dimers to the invariant chain trimer and alpha beta complex ((alpha beta)1:(Ii)3) forms the complete nonameric structure ((alpha beta:Ii)3). Calnexin then disassociates on egress of the nonameric complex from the ER.
