Schematic showing organisation of domains within titin molecule. Arrangement of Ig and Fn3 domains in different regions of titin are shown. PROSITE MyDomains Image Creator was used to arrange domains for each section.

The table below gives domain boundaries according to positions in the IC (inferred complete) isoform of titin. The isoforms in which a particular domain is found are specified. Click on a domain name for more information.
