Summary
| Description |
English: Mechanisms of VSG switching in T. brucei:
A. Structure of the expression site including the expression site associated genes (ESAG), 70 base pair repeat up-stream sequence, expressed VSG gene, and the telomere B. Mechanism of array VSG conversion: A silent VSG is copied from a subtelomeric VSG array into an ES, where it replaces the active VSG. C. Telomeric VSG conversion: A telomeric VSG (including 70 bp repeat sequence upstream and telomere downstream) replaces the active VSG in the ES D. Segmental VSG conversion: Sequence is copied from multiple inactive VSG genes and combined into a novel mosaic VSG that occupies the ES E. Transcriptional VSG switching: A non-recombination based mechanism that activates a new (previously silent) ES, while inactivating the previously active ES. |

{{vector version available|new image name}}.
It is recommended to name the SVG file “Mechanisms of VSG switching2.svg”—then the template Vector version available (or Vva) does not need the new image name parameter. |
