A single amino acid substitution within the matrix protein of a type D retrovirus converts its morphogenesis to that of a type C retrovirus
Abstract
Two different morphogenic processes of retroviral capsid assembly have been observed: the capsid is either assembled at the plasma membrane during the budding process (type C), or preassembled within the cytoplasm (types B and D). We describe here a gag mutant of Mason-Pfizer monkey virus, a type D retrovirus, in which a tryptophan substituted for an arginine in the matrix protein results in efficient assembly of capsids at the plasma membrane through a morphogenic process similar to that of type C retroviruses. We conclude that a type D retrovirus Gag polyprotein contains an additional, dominant signal that prevents immediate transport of precursors from the site of biosynthesis to the plasma membrane. Instead, they are directed to and retained at a cytoplasmic site where a concentration sufficient for self-assembly into capsids occurs. Thus, capsid assembly processes for different retroviruses appear to differ only in the intracellular site to which capsid precursors are directed.

In the citing paper
“The critical role of Gag in virion assembly has been clearly demonstrated by amino acid substitutions(s) in the MA sequence of MPMV, MMTV, JSRV, and spumaviruses, resulting in the relocation of their assembly from cytoplasm to the plasma membrane—a major shift from a type D to a type C pattern”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
