General annotation (Comments)

Function

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.

Subunit structure

Homotrimer By similarity.

Subcellular location

Cytoplasm By similarity.

Induction

Ty1-A is a weakly expressed element. Induced under amino acid starvation conditions by GCN4. Ref.5

Domain

The C-terminal RNA-binding region of CA is sufficient for all its nucleocapsid-like chaperone activities By similarity.

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).

Caution

Transposon Ty1-A (YARCTy1-1) contains a frameshift at position 610, which disrupts the ORF coding for protein TY1B.
