(A) Graphical representation of domains on the sequence ADA19_HUMAN. The sequence is represented as a grey bar. As of release 18.0, Pfam identifies four domains: Pep_M12B_propep (PF01562, coloured green), Reprolysin (PF01421, red), Disintegrin (PF00200, yellow) and EGF_2 (PF07974, magenta). The black domain is the ACR domain from SMART (15). The striped boxes represent PfamB families, while the small blue and red boxes represent low-complexity and transmembrane regions respectively. Above the domain images, the dashed lines represent disulphide bridges found within the sequence. The red diamond below the Reprolysin domain indicates an active site position. (B) The seed alignment of SH2 (PF00017) marked-up according to the Belvu colouring system, using the new multiple sequence alignment viewer on the Swedish site.

Clan pages in Pfam. (A) A screen shot of a clan summary page, containing the description, annotation and membership of the clan. From this page, the user can view the family relationship diagram (B). Each family in the clan is represented by a blue box and its relationship to other families is represented by solid lines (significant profile–profile comparison score) or dashed lines (non-significant profile-profile comparison score). Beside each line, the profile–profile comparison E-value score is presented. This score is also linked to a visualization of the profile–profile comparison alignment (C). The clan summary page also provides a link to the clan alignment (D) (for more details see text). The clan alignment is a multiple sequence alignment of all of the clan members seed alignments (each set of seed sequences are separated by the alternate background shading). The alignments are coloured using Jalview.
