What's a GeneRIF?

phosphorylation of D. melanogaster flightin is modulated during flight
Title: Intrinsic disorder and multiple phosphorylations constrain the evolution of the flightin N-terminal region.
COOH terminus of flightin is necessary for normal myofilament lattice organization, thereby facilitating the cross-bridge binding required to achieve high power output for flight.
Title: COOH-terminal truncation of flightin decreases myofilament lattice organization, cross-bridge binding, and power output in Drosophila indirect flight muscle.
used atomic force microscopy to study the morphological and mechanical properties of fully hydrated native thick filaments isolated from indirect flight muscle of normal and mutants lacking flightin
Title: Flightin is necessary for length determination, structural integrity, and large bending stiffness of insect flight muscle thick filaments.
Results illustrate the importance of flightin in flight muscle development and function.
Title: Flight muscle properties and aerodynamic performance of Drosophila expressing a flightin transgene.
Flightin is a major contributor to myofilament stiffness and a key determinant of the enhanced delayed force response to stretch in Drosophila flight muscles.
Title: Mutations that affect flightin expression in Drosophila alter the viscoelastic properties of flight muscle fibers.
Myofilin is probably needed for filament assembly in all muscles, and flightin for stability of flight muscle thick filaments in adult flies
