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-C Gag polyprotein;
CC         IsoId=P25383-1; Sequence=Displayed;
CC       Name=Transposon Ty2-C Gag-Pol polyprotein;
CC         IsoId=P25384-1; 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-C Gag polyprotein]: Produced by
CC       conventional translation.
