The predicted secondary structure formed by ApoB mRNA is thought to allow for contact between the residue to be edited and the active site of APOBEC1 as well as for binding of ACF and other auxiliary factors associated with the editosome.
A estrutura secundaria predita formada polo ARNm da ApoB crese que permite o contacto entre o residuo que vai ser editado e o sitio activo da APOBEC1 e tamén permite a unión ao ACF e outros factores auxiliares asociados co editosoma.
