    Functioni

    Capsid protein (CA) is the structural component of the virus-like particle (VLP), forming the shell that encapsulates the retrotransposons dimeric RNA genome. The particles are assembled from trimer-clustered units and there are holes in the capsid shells that allow for the diffusion of macromolecules. CA has also nucleocapsid-like chaperone activity, promoting primer tRNA(i)-Met annealing to the multipartite primer-binding site (PBS), dimerization of Ty2 RNA and initiation of reverse transcription By similarity.By similarity

    The sequence of this isoform can be found in the external entry Q12501.
    Isoforms of the same protein are often annotated in two different entries if their sequences differ significantly.

    Note: Produced by +1 ribosomal frameshifting between codon Leu-431 and Gly-432 of the YOR343W-A ORF.

    Miscellaneousi

    Miscellaneous

    Retrotransposons are mobile genetic entities that are able to replicate via an RNA intermediate and a reverse transcription step. In contrast to retroviruses, retrotransposons are non-infectious, lack an envelope and remain intracellular. Ty2 retrotransposons belong to the copia elements (pseudoviridae).
