Human cardiac troponin complex. Structure and functions

Biochemistry (Moscow), 2013
Troponin complex is a component of skeletal and cardiac muscle thin filaments. It consists of three subunits - troponin I, T, and C, and it plays a crucial role in muscle activity, connecting changes in intracellular Ca2+ concentration with generation of contraction.

The troponin complex and regulation of muscle contraction

The FASEB Journal, 1995
In a wide variety of cellular settings, from organelle transport to muscle contraction, Ca2+ binding to members of the EF hand family of proteins controls the interaction between actin and different myosins that are responsible for generating movement. In vertebrate skeletal and cardiac muscle the Ca(2+)-binding protein troponin C (TnC) is one subunit ...

RESOLUTION OF BRAIN TROPONIN COMPLEX

Journal of Neurochemistry, 1979
AbstractAffinity chromatography was used to partially purify the troponin complex from crude regulatory proteins obtained from bovine brain cortex. Three components were obtained from this partially purified troponin complex by treatment with 6 M‐urea and 1 mM‐EGTA followed by chromatography on DEAE‐Sephadex‐A50.

Physarum Tropomyosin-Troponin Complex

The Journal of Biochemistry, 1975
The relaxing protein (TM-TN complex) was isolated from plasmodia of Physarum. SDS-gel electrophoresis revealed that the relaxing protein consists of tropomyosin subunits with a molecular weight of 35,000 troponin subunits with molecular weights of 38,000 (T) and 24,000 (I) and several other components. No component corresponding to muscle troponinC (MW-

Structure of the insect troponin complex 1 1Edited by M. F. Moody

Journal of Molecular Biology, 1999
Isolated troponin-tropomyosin complex from Lethocerus indicus asynchronous flight muscle forms paracrystals on a positively charged lipid monolayer. Single particle analysis was carried out on individual complexes selected from electron micrographs of negatively stained paracrystals.

Extraction and Replacement of the Tropomyosin–Troponin Complex in Isolated Myofibrils

Advances in Experimental Medicine and Biology, 2010
Tropomyosin (Tm) is an essential component in the regulation of striated muscle contraction. Questions about Tm functional role have been difficult to study because sarcomere Tm content is not as easily manipulated as Troponin (Tn). Here we describe the method we recently developed to replace Tm-Tn of skeletal and cardiac myofibrils from animals and ...

Proximity Relationships between Residue 6 of Troponin I and Residues in Troponin C:  Further Evidence for Extended Conformation of Troponin C in the Troponin Complex

Biochemistry, 2000
Skeletal muscle troponin C (TnC) adopts an extended conformation when crystallized alone and a compact one when crystallized with an N-terminal troponin I (TnI) peptide, TnI(1-47) [Vassylyev et al. (1998) Proc. Natl. Acad. Sci. U.S.A. 95, 4847-4852]. The N-terminal region of TnI (residues 1-40) was suggested to play a functional role of facilitating ...
