Detection and immunochemical characterization of a primate type C retrovirus-related p30 protein in normal human placentas

L B Jerabek et al. Proc Natl Acad Sci U S A. 1984 Oct.

Abstract

We find that 12 of 14 specimens of normal human term placentas analyzed by one- or two-dimensional electrophoresis and immunoblotting contain a protein or polypeptide of approximately equal to 30,000 daltons that is antigenically cross-reactive with p30 core protein of the simian sarcoma-associated virus/gibbon ape leukemia virus primate retrovirus group and is physicochemically similar to reference murine and primate type C retrovirus p30s. This finding may lead to an understanding of endogenous type C retrovirus gene expression in humans.
