  In a scenario where the constituent quarks are composite systems, Generalized
Parton Distributions (GPDs) are built from wave functions to be evaluated in a
Constituent Quark Model (CQM), convoluted with the GPDs of the constituent
quarks themselves. The approach permits to access the kinematical range
corresponding to the DGLAP and ERBL regions, so that cross sections for deeply
virtual Compton scattering could be estimated.
