Purity: > 95% by SDS - PAGE Format: Liquid. 20mM Tris-HCl buffer (pH8.0) containing 20% glycerol, 0.1M NaCl,1mM DTT. CRCP, also known as CGRP-RCP, is an ubiquitous coupling protein for the calcitonin gene-related peptide and adrenomedullin receptors. It modulates ligand responsiveness in a variety of tissues. It has been DNA-directed RNA polymerase activity, catalytic activity and calcitonin receptor activity. Recombinant human CRCP protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography.
