protein

Polypeptide derived from translation of mRNA. The human genome contains about 20,000-25,000 protein-coding genes. [1] Function: - proteins are 'building blocks of life' - proteins may have a diversity of functions - proteins may associate to form transient or stable molecular complexes Structure: - the sequence of amino acids in a protein is defined by its mRNA transcribed from its gene - amino acid residues in a protein may be chemically altered in post-translational modification Compartment: - a protein may be associated with a specific cellular or extracellular compartment Expression: - a protein may be specifically expressed by particular cell types Pharmacokinetics: - a protein may be stable or turnover rapidly Pathology: - a protein play a role in disease processes via: a) overexpression b) underexpression c) aberrant structure & function
