Key result
Myosin, α-actinin, and Sallimus order before actin, driving sarcomere self-assembly via non-local interactions.
Why the study?
The mechanism of molecular ordering during sarcomere assembly remains debated despite well-characterized organization in mature sarcomeres.
Proposes a theoretical framework and mathematical model for sarcomere self-assembly where myosin, Sallimus, and Z-disc proteins establish periodicity before actin filaments.

Hypothesis-generating in Drosophila; requires mammalian validation before any clinical relevance.
Kolley et al. (2023) studied Myofibrillogenesis. Myosin, α-actinin, and the titin homologue Sallimus form periodic patterns before actin during sarcomere assembly in Drosophila flight muscles, supporting a model of self-assembly driven by non-local interactions.
