title: Titin-related proteins in invertebrate muscles.
abstract: The localization of filaments connecting the Z-line and the A-band in insect flight muscles and the identification of very large proteins as their components is reviewed. The characterization of twitchin in the obliquely striated muscles of Caenorhabditis elegans is reported and the deductions made from its amino acid sequence are considered. The characterization of mini-titins in obliquely striated molluscan muscles is compared. The identification of projectin in the muscles of Drosophila melanogaster by anti-twitchin-antibodies, its sequence analysis and the characterization of mini-titins in arthropod and mollusc fast-striated muscles are summarized. The possible biological functions of the different proteins in various invertebrate muscles are discussed.
