Subcellular distribution of newly synthesized virus-specific polypeptides in Moloney murine leukemia virus infected cells. 1979

G Shanmugam

Immune precipitation analysis of pulse-labeled proteins present in subcellular fractions of mouse embryo cells infected with Moloney murine leukemia virus showed the presence of anti-gp70 serum-precipitable viral envelope gene products mainly in the microsomal fractions of these cells. In contrast, anti-p30 serum-specific gag (group specific antigen) gene products were found to be distributed in similar amounts in both the microsomal and postmicrosomal supernatant fractions of pulse-labeled cells.

UI	MeSH Term	Description	Entries
D008861	Microsomes	Artifactual vesicles formed from the endoplasmic reticulum when cells are disrupted. They are isolated by differential centrifugation and are composed of three structural features: rough vesicles, smooth vesicles, and ribosomes. Numerous enzyme activities are associated with the microsomal fraction. (Glick, Glossary of Biochemistry and Molecular Biology, 1990; from Rieger et al., Glossary of Genetics: Classical and Molecular, 5th ed)	Microsome
D008979	Moloney murine leukemia virus	A strain of Murine leukemia virus (LEUKEMIA VIRUS, MURINE) arising during the propagation of S37 mouse sarcoma, and causing lymphoid leukemia in mice. It also infects rats and newborn hamsters. It is apparently transmitted to embryos in utero and to newborns through mother's milk.
