Lincruvirus (taxid:2508256)



Enveloped, spherical. Diameter from 80 to 120nm.



Segmented Negative-stranded RNA linear genome, L segment is about 6.7kb, M segment about 3.3kb and S segment about 0.8kb.
Encodes for 3 proteins.


Transcription starts by viral RNA dependent RNA polymerase (L) binding to a promoter on each encapsidated segment, and is terminated by a strong hairpin sequence at the end of each gene. mRNAs are capped by L protein during synthesis using cap snatching ., but are not polyadenylated.

Enzymes: RNA dependent RNA polymerase, endonuclease (cap-snatching)




  1. Virus attaches to host receptors though G glycoprotein, and is endocytosed into vesicles in the host cell.
  2. Fusion of virus membrane with the vesicle membrane; ribonucleocapsid segments are released in the cytoplasm.
  3. Transcription, viral mRNAs are capped in the cytoplasm.
  4. Replication presumably starts when enough nucleoprotein is present to encapsidate neo-synthetized antigenomes and genomes.
  5. The ribonucleocapsids buds at Golgi apparatus, releasing the virion by exocytosis.
These structures were created with the help of Colabfold by Jason Nomburg, Nathan Price and Jennifer Doudna (ModelArchive).
