We present renormalization constants of overlap quark bilinear operators on
2+1-flavor domain wall fermion configurations. Both overlap and domain wall
fermions have chiral symmetry on the lattice. The scale independent
renormalization constant for the local axial vector current is computed using a
Ward Identity. The renormalization constants for the scalar, pseudoscalar and
vector current are calculated in the RI-MOM scheme. Results in the MS-bar
scheme are obtained by using perturbative conversion ratios. The analysis uses
in total six ensembles with lattice sizes 24^3x64 and 32^3x64.Comment: 7 pages, 10 figures, presented at the 31st International Symposium on
