Abstract
Kettin is a unique member of the connectin/titin family of muscle elastic proteins, which has repetitive immunoglobulin-like domains that are separated by weakly conserved linker sequences. In striated muscles of insects and crayfish, kettin binds to actin filaments and localizes to the Z-disc and its adjacent region in the I-band. Recent sequence analysis of invertebrate connectin/titin (also known as SLS proteins) has revealed that kettin is a splice variant of connectin/titin. In contrast, in the nematode Caenorhabditis elegans, the kettin gene is independent of the genes for other connectin/titin-related proteins. Immunofluorescent localization of kettin shows that it localizes to the I-bands in the obliquely striated body wall muscle. Therefore, C. elegans is an attractive model system to study specific functions of kettin in muscle cells.Entities:
