Abstract

The HIV-1 capsid protein forms the conical core structure at the center of the mature virion. Capsid also binds the human peptidyl prolyl isomerase, cyclophilin A, thereby packaging the enzyme into the virion. Cyclophilin A subsequently performs an essential function in HIV-1 replication, possibly helping to disassemble the capsid core upon infection. We report the 2.36 A crystal structure of the N-terminal domain of HIV-1 capsid (residues 1-151) in complex with human cyclophilin A. A single exposed capsid loop (residues 85-93) binds in the enzyme's active site, and Pro-90 adopts an unprecedented trans conformation. The structure suggests how cyclophilin A can act as a sequence-specific binding protein and a nonspecific prolyl isomerase. In the crystal lattice, capsid molecules assemble into continuous planar strips. Side by side association of these strips may allow capsid to form the surface of the viral core. Cyclophilin A could then function by weakening the association between capsid strips, thereby promoting disassembly of the viral core.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

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.
