The Structural Biology of Septins and Their Filaments: An Update
In order to fully understand any complex biochemical system from a mechanistic point of view, it is necessary to have access to the three-dimensional structures of the molecular components involved. Septins and their oligomers, filaments and higher-order

Disease-related cardiac troponins alter thin filament Ca2+ association and dissociation rates. [PDF]
The contractile response of the heart can be altered by disease-related protein modifications to numerous contractile proteins. By utilizing an IAANS labeled fluorescent troponin C, [Formula: see text], we examined the effects of ten disease-related ...

Multiple sites in αB-crystallin modulate its interactions with desmin filaments assembled in vitro. [PDF]
The β3- and β8-strands and C-terminal residues 155-165 of αB-crystallin were identified by pin arrays as interaction sites for various client proteins including the intermediate filament protein desmin.

Thick filament‐associated myosin undergoes frequent replacement at the tip of the thick filament
Myosin plays a fundamental role in muscle contraction. Approximately 300 myosins form a bipolar thick filament, in which myosin is continuously replaced by protein turnover.

The force of the myosin motor sets cooperativity in thin filament activation of skeletal muscles
Sarcomeres of Ca2 + -activated demembranated fibres of rabbit soleus muscles show that the stress exerted by each motor protein on the thin filament determines the cooperativity in thin filament activation.

Structural and Functional Studies of H. seropedicae RecA Protein - Insights into the Polymerization of RecA Protein as Nucleoprotein Filament. [PDF]
The bacterial RecA protein plays a role in the complex system of DNA damage repair. Here, we report the functional and structural characterization of the Herbaspirillum seropedicae RecA protein (HsRecA). HsRecA protein is more efficient at displacing SSB

Distribution of glial fibrillary acidic protein in different parts of the rat brain under cadmium exposure [PDF]
The chronic effects of low doses of cadmium on the distribution of soluble and filament forms of glial fibrillary acidic protein (GFAP) and their polypeptide fragments in different parts of the rat brain were investigated.

Sarcomere lattice geometry influences cooperative myosin binding in muscle. [PDF]
In muscle, force emerges from myosin binding with actin (forming a cross-bridge). This actomyosin binding depends upon myofilament geometry, kinetics of thin-filament Ca(2+) activation, and kinetics of cross-bridge cycling.
