Detection and immunochemical characterization of a primate type C retrovirus-related p30 protein in normal human placentas. 1984

L B Jerabek, and R C Mellors, and K B Elkon, and J W Mellors

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.

UI MeSH Term Description Entries
D007526 Isoelectric Point The pH in solutions of proteins and related compounds at which the dipolar ions are at a maximum. Isoelectric Points,Point, Isoelectric,Points, Isoelectric

D010920 Placenta A highly vascularized mammalian fetal-maternal organ and major site of transport of oxygen, nutrients, and fetal waste products. It includes a fetal portion (CHORIONIC VILLI) derived from TROPHOBLASTS and a maternal portion (DECIDUA) derived from the uterine ENDOMETRIUM. The placenta produces an array of steroid, protein and peptide hormones (PLACENTAL HORMONES). Placentoma, Normal,Placentome,Placentas,Placentomes
D011247 Pregnancy The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH. Gestation,Pregnancies

D012190 Retroviridae Family of RNA viruses that infects birds and mammals and encodes the enzyme reverse transcriptase. The family contains seven genera: DELTARETROVIRUS; LENTIVIRUS; RETROVIRUSES TYPE B, MAMMALIAN; ALPHARETROVIRUS; GAMMARETROVIRUS; RETROVIRUSES TYPE D; and SPUMAVIRUS. A key feature of retrovirus biology is the synthesis of a DNA copy of the genome which is integrated into cellular DNA. After integration it is sometimes not expressed but maintained in a latent state (PROVIRUSES).
