ERA (E. coli Ras-like protein) Anti-Human Rabbit IgG Affinity Purify

ERA (Escherichia coli Ras-like protein) is an E. coli GTP binding protein that is essential for proliferation. A DNA database search suggests that homologous sequences with ERA exist in various organisms including human, mouse, Drosophila, Caenorhabditis elegans and Antirrhinum majus. However, the physiological function of eukaryotic ERA-like proteins is not known. The human homologue has been cloned. The mammalian homologue of ERA consists of a typical GTPase/GTP-binding domain and a putative K homology (KH) domain, which is known as an RNA binding domain. Human ERA processing the amino acid substitution mutation into the GTPase domain induced apoptosis of HeLa cells, which was blocked by Bcl-2 expression. Thus, human ERA plays an important role in the regulation of apoptotic signaling with its GTPase/GTP binding domain. For research use only, not for use in diagnostic procedures.
