Figure 1. The TRIM25 B30.2 domain structure.
(A) Domain architecture of the full-length TRIM25 molecule highlighting the PRY (blue) and SPRY (red) tandem sequence motifs that comprise the B30.2 domain. (B) Cartoon representation of the three-dimensional structure of the TRIM25 B30.2 domain with the PRY and SPRY regions coloured blue and red respectively. α-Helices and key loops are annotated. (C) Topology diagram of the TRIM25 B30.2 domain with the structural elements coloured according to PRY (blue) and SPRY (red). α-Helices and β-strands are numbered and shown as rounded rectangles and arrows respectively. Loop regions are numbered L1–L13.
