Figure 4

N-terminal domain architecture of a selection of sponge Adhesion GPCRs. The domains were identified by aligning sponge Adhesions to the latest version of Pfam library. Few Adhesion GPCR sequences that lack N-terminal domains are not shown. The domains shown in the figure include; 7TM: seven-transmembrane domain, DUF: Domain of unknown function, EGF: epidermal growth factor-like domain, fn3: fibronectin type III domain, GPS: GPCR proteolytic site domain, HRM: Hormone receptor domain, IG/IG_2/IG_3: immunoglobulin domains, I-set: Immunoglobulin I-set domain, SNARE: soluble N-ethylmaleimide-sensitive factor (NSF) attachment protein (SNAP) receptor domain, SRCR: Scavenger receptor cysteine-rich domain, V-set: Immunoglobulin V-set domain.
