## Abstract Protein disulfide isomerase ERp57 is localized predominantly in the endoplasmic reticulum, but is also present in the cytosol and, according to preliminary evidence, in the nucleus of avian cells. Conclusive evidence of its nuclear localization and of its interaction with DNA in vivo in
Protein ERp60, previously found in the internal nuclear matrix in chicken liver nuclei, is a member of the protein disulfide isomerase family. It binds DNA and double helical polynucleotides in vitro with a preferential recognition toward the matrix-associated regions of DNA and poly(dA) x poly(dT),
