Fig. 1From: Molecular characterization and expression patterns of a non-mammalian toll-like receptor gene (TLR21) in larvae ontogeny of common carp (Cyprinus carpio L.) and upon immune stimulationThe domain organizations for TLR21 in various species. Schematic representation of TLR21 domains was predicted by SMART. N-terminal signal peptide (red box), LRRs and LRR-CT domain are denoted at the extracellular region, followed by a transmembrane domain (blue box), and a TIR domain in the cytoplasmic regionBack to article page
