Function[PAR4_HUMAN] Receptor for activated thrombin or trypsin coupled to G proteins that stimulate phosphoinositide hydrolysis. May play a role in platelets activation.[1] Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedBiologically important human proteins often require mammalian cell expression for structural studies, presenting technical and economical problems in the production/purification processes. We introduce a novel affinity peptide tagging system that uses a low affinity anti-peptide monoclonal antibody. Concatenation of the short recognition sequence enabled the successful engineering of an 18-residue affinity tag with ideal solution binding kinetics, providing a low-cost purification means when combined with nondenaturing elution by water-miscible organic solvents. Three-dimensional information provides a firm structural basis for the antibody-peptide interaction, opening opportunities for further improvements/modifications.
