molecular process trimerization 2022-02-01T09:40:48Z MOP:0000715 The formation of a trimer from three molecular subunits. The GO class "protein trimerization" (https://purl.obolibrary.org/obo/GO_0070206) would actually be a subclass of "trimerization" according to the definition provided here. However, for the reason of not wanting to inject this subclassOf axiom into GO, we decided to not assert this in MOP as of yet. Further discussion is needed with the GO and/or OBO team to see how this GO class can be integrated.
