PR is a shorthand for protein, which means protein.

Protein is a complex organic compound. It is formed by the linear arrangement of amino acid molecules, and the carboxyl and amino groups of adjacent amino acid residues are linked together by the formation of peptide bonds. The amino acid sequence of a protein is encoded by the corresponding gene.

In addition to the 20 "standard" amino acids encoded in the genetic code, certain amino acid residues in proteins can also be modified post-translationally to undergo changes in chemical structure that can activate or regulate proteins. Multiple proteins can work together, often by combining together to form stable protein complexes that perform a specific function.
