Key result
Zeugmatin is part of the Z-band region of titin, and overexpression of a zeugmatin-GFP fusion protein in muscle cells inhibits myofibrillogenesis and disassembles preexisting myofibrils.

Zeugmatin modulation may affect myofibril stability; leaves open relevance to human titin-related myopathies.
Zeugmatin is identified as part of the Z-band region of titin, playing a crucial role in organizing and maintaining myofibril structure.
Turnacioglu et al. (1997) studied this question. Z1.1 GFP fusion protein vs. GFP alone was evaluated on Myofibril assembly and structure. Zeugmatin is part of the Z-band region of titin, and overexpression of a zeugmatin-GFP fusion protein in muscle cells inhibits myofibrillogenesis and disassembles preexisting myofibrils.
