    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 Ty1 RNA and initiation of reverse transcription By similarity.By similarity
    The aspartyl protease (PR) mediates the proteolytic cleavages of the Gag and Gag-Pol polyproteins after assembly of the VLP.By similarity
    Reverse transcriptase/ribonuclease H (RT) is a multifunctional enzyme that catalyzes the conversion of the retro-elements RNA genome into dsDNA within the VLP. The enzyme displays a DNA polymerase activity that can copy either DNA or RNA templates, and a ribonuclease H (RNase H) activity that cleaves the RNA strand of RNA-DNA heteroduplexes during plus-strand synthesis and hydrolyzes RNA primers. The conversion leads to a linear dsDNA copy of the retrotransposon that includes long terminal repeats (LTRs) at both ends By similarity.By similarity
    Integrase (IN) targets the VLP to the nucleus, where a subparticle preintegration complex (PIC) containing at least integrase and the newly synthesized dsDNA copy of the retrotransposon must transit the nuclear membrane. Once in the nucleus, integrase performs the integration of the dsDNA into the host genome By similarity.By similarity

    Post-translational modificationi

    Initially, virus-like particles (VLPs) are composed of the structural unprocessed proteins Gag and Gag-Pol, and contain also the host initiator methionine tRNA (tRNA(i)-Met) which serves as a primer for minus-strand DNA synthesis, and a dimer of genomic Ty RNA. Processing of the polyproteins occurs within the particle and proceeds by an ordered pathway, called maturation. First, the protease (PR) is released by autocatalytic cleavage of the Gag-Pol polyprotein yielding capsid protein p45 and a Pol-p154 precursor protein. This cleavage is a prerequisite for subsequent processing of Pol-p154 at the remaining sites to release the mature structural and catalytic proteins. Maturation takes place prior to the RT reaction and is required to produce transposition-competent VLPs By similarity.By similarity

    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. Ty1 retrotransposons belong to the copia elements (pseudoviridae).
