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 Ty1 RNA and
CC initiation of reverse transcription (By similarity). {ECO:0000250}.
CC -!- FUNCTION: The aspartyl protease (PR) mediates the proteolytic cleavages
CC of the Gag and Gag-Pol polyproteins after assembly of the VLP.
CC {ECO:0000250}.
CC -!- FUNCTION: Reverse transcriptase/ribonuclease H (RT) is a
CC multifunctional enzyme that catalyzes the conversion of the retro-
CC elements RNA genome into dsDNA within the VLP. The enzyme displays a
CC DNA polymerase activity that can copy either DNA or RNA templates, and
CC a ribonuclease H (RNase H) activity that cleaves the RNA strand of RNA-
CC DNA heteroduplexes during plus-strand synthesis and hydrolyzes RNA
CC primers. The conversion leads to a linear dsDNA copy of the
CC retrotransposon that includes long terminal repeats (LTRs) at both ends
CC (By similarity). {ECO:0000250}.
CC -!- FUNCTION: Integrase (IN) targets the VLP to the nucleus, where a
CC subparticle preintegration complex (PIC) containing at least integrase
CC and the newly synthesized dsDNA copy of the retrotransposon must
CC transit the nuclear membrane. Once in the nucleus, integrase performs
CC the integration of the dsDNA into the host genome (By similarity).
CC {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a 2'-deoxyribonucleoside 5'-triphosphate + DNA(n) =
CC diphosphate + DNA(n+1); Xref=Rhea:RHEA:22508, Rhea:RHEA-COMP:17339,

CC -!- CATALYTIC ACTIVITY:

CC ChEBI:CHEBI:173112; EC=2.7.7.7;
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Endonucleolytic cleavage to 5'-phosphomonoester.; EC=3.1.26.4;
CC -!- SUBUNIT: The capsid protein forms a homotrimer, from which the VLPs are
CC assembled. The protease is a homodimer, whose active site consists of
CC two apposed aspartic acid residues (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm. Nucleus {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. The ratio of Gag:Gag-Pol varies between 20:1 and 5:1 (By
CC similarity). {ECO:0000250};
CC Name=Transposon Ty1-BR Gag-Pol polyprotein;
CC IsoId=Q12193-1; Sequence=Displayed;
CC Name=Transposon Ty1-BR Gag polyprotein;
CC IsoId=Q12217-1; 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 -!- DOMAIN: Integrase core domain contains the D-x(n)-D-x(35)-E motif,
CC named for the phylogenetically conserved glutamic acid and aspartic
CC acid residues and the invariant 35 amino acid spacing between the
CC second and third acidic residues. Each acidic residue of the D,D(35)E
CC motif is independently essential for the 3'-processing and strand
CC transfer activities of purified integrase protein (By similarity).
CC {ECO:0000250}.
CC -!- PTM: Initially, virus-like particles (VLPs) are composed of the
CC structural unprocessed proteins Gag and Gag-Pol, and also contain the
CC host initiator methionine tRNA (tRNA(i)-Met) which serves as a primer
CC for minus-strand DNA synthesis, and a dimer of genomic Ty RNA.
CC Processing of the polyproteins occurs within the particle and proceeds
CC by an ordered pathway, called maturation. First, the protease (PR) is
CC released by autocatalytic cleavage of the Gag-Pol polyprotein yielding
CC capsid protein p45 and a Pol-p154 precursor protein. This cleavage is a
CC prerequisite for subsequent processing of Pol-p154 at the remaining
CC sites to release the mature structural and catalytic proteins.
CC Maturation takes place prior to the RT reaction and is required to
CC produce transposition-competent VLPs (By similarity). {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. Ty1 retrotransposons belong
CC to the copia elements (pseudoviridae).
CC -!- MISCELLANEOUS: [Isoform Transposon Ty1-BR Gag-Pol polyprotein]:
CC Produced by +1 ribosomal frameshifting between codon Leu-435 and Gly-
CC 436 of the YBR012W-A ORF.
