CC -!- FUNCTION: Capsid protein (CA) is the structural component of the virus-
CC like particle (VLP), forming the shell that encapsulates the
CC retrotransposons dimeric RNA genome. The particles are assembled from
CC trimer-clustered units and there are holes in the capsid shells that
CC allow for the diffusion of macromolecules. CA has also nucleocapsid-
CC like chaperone activity, promoting primer tRNA(i)-Met annealing to the
CC multipartite primer-binding site (PBS), dimerization of Ty2 RNA and
CC initiation of reverse transcription (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Homotrimer. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Ribosomal frameshifting; Named isoforms=2;
CC Comment=The Gag-Pol polyprotein is generated by a +1 ribosomal
CC frameshift.;
CC Name=Transposon Ty2-GR2 Gag polyprotein;
CC IsoId=P0CX62-1; Sequence=Displayed;
CC Name=Transposon Ty2-GR2 Gag-Pol polyprotein;
CC IsoId=P0CX64-1; Sequence=External;
CC -!- DOMAIN: The C-terminal RNA-binding region of CA is sufficient for all
CC its nucleocapsid-like chaperone activities. {ECO:0000250}.
CC -!- MISCELLANEOUS: Retrotransposons are mobile genetic entities that are
CC able to replicate via an RNA intermediate and a reverse transcription
CC step. In contrast to retroviruses, retrotransposons are non-infectious,
CC lack an envelope and remain intracellular. Ty2 retrotransposons belong
CC to the copia elements (pseudoviridae).
CC -!- MISCELLANEOUS: [Isoform Transposon Ty2-GR2 Gag polyprotein]: Produced
CC by conventional translation.
