Binding domain

From Wikipedia, the free encyclopedia

A binding domain is a protein domain which binds to a specific atom or molecule, such as calcium or DNA. Protein Domain is a part of a protein sequence and a tertiary structure that can change, function, and live by itself for the rest of the protein chain. (Phillips 1). Upon binding, proteins may undergo a conformational change. Binding domains are essential for the function of many proteins. They are essential because they help splice, assemble, and translate proteins. (Yong 1).

Examples of binding domains include Zinc finger, which binds to DNA, and EF hand, which binds to calcium.
