We derive a two-parameter formula for the electromagnetic form factors of thenucleon described as an instanton by "integrating out" all KK modes other thanthe lowest mesons from the infinite-tower of vector mesons in holographic QCDwhile preserving hidden local symmetry for the resultant vector fields. Withonly two parameters, the proton Sachs form factors can be fit surprisingly wellto the available experimental data for momentum transfers $Q^2\lsim 0.5$GeV$^2$ with $\chi^2$/dof $\lsim 2$, indicating the importance of an infinitetower in the soliton structure of the nucleon. The prediction of theSakai-Sugimoto holographic dual model is checked against the fit values that weinterpret as representing Nature. The nature of the "core" in the nucleonstructure is reassessed in light of the results obtained with theinfinite-tower structure.
