  We report the status of RBCK calculations on nucleon structure with quenched
and dynamical domain wall fermions. The quenched results for the moments of
structure functions (< x >_q), (< x>_{\Delta u - \Delta d}), and (< 1 >_{\delta
q}) from 1.3 GeV cutoff lattices are complete with non perturbative
renormalization (NPR). The dynamical results with two degenerate dynamical
quark flavors from 1.7 GeV cutoff lattices are without NPR while the axial
charge result is naturally renormalized.
