Troponin C

Troponin C is a part of the troponin complex. It contains four calcium-binding EF hands, although different isoforms may have fewer than four functional calcium-binding subdomains. It is a component of thin filaments (along with actin and tropomyosin). It contains an N lobe and a C lobe. The C lobe serves a structural purpose and binds to the N domain of troponin I (TnI). The C lobe can bind either Ca²⁺ or Mg²⁺. The N lobe, which binds only Ca²⁺, is the regulatory lobe and binds to the C domain of troponin I after calcium binding.

The tissue specific subtypes are:

Tournament of Champions (debate)

The Tournament of Champions (TOC) is a national high school debate tournament held at the University of Kentucky every year on the last weekend in April. The Tournament is considered the national championship of the “National Circuit,” with debaters having to apply to compete. It is considered the most prestigious and competitive American high school debate tournament. The tournament uses a bid system, in which placing high enough in certain, nationally or regionally respected tournaments earns debaters a bid, with at least 2 bids needed to compete. In addition to this, competitors can automatically qualify by placing high enough at last year’s tournament (or one of the two other national tournaments) or by getting accepted as an at large entry.

The tournament was created by Dr. J.W. Patterson, the former director of debate at the University of Kentucky. Incepted in 1972, it serves as the pinnacle of high school debate, allowing the best debaters in the United States to compete without other, less experienced debaters affecting the rankings. The Tournament currently holds competition in policy debate, Lincoln–Douglas debate, public forum debate, and Congressional Debate.
