Protein

Transposon Ty4-H Gag-Pol polyprotein

Gene

TY4B-H

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed - Annotation score: 5 out of 5- Protein inferred from homologyi

Functioni

Capsid protein (CA) is the structural component of the virus-like particle (VLP), forming the shell that encapsulates the retrotransposons dimeric RNA genome.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

Catalytic activityi

Deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1).
Endonucleolytic cleavage to 5'-phosphomonoester.

Post-translational modificationi

Proteolytically processed into capsid protein (CA), Ty4 protease (PR), integrase (IN) and reverse transcriptase/ribonuclease H (RT) proteins (Probable). 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, and this cleavage is a prerequisite for subsequent processing 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 similarityCurated

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. Ty4 retrotransposons belong to the copia elements (pseudoviridae).
