Protein

Transposon Ty1-BL Gag polyprotein

Gene

TY1A-BL

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at protein leveli

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

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