GNB1 Recombinant Protein

Source : Escherichia Coli. GNB1 Human Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 363 amino acids (1-340) and having a molecular mass of 39.8 kDa.GNB1 is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques. Heterotrimeric guanine nucleotide-binding proteins (G proteins) which integrate signals between receptors and effector proteins, are comprised of an alpha, a beta and a gamma subunit. The alpha, beta and gamma subunits are encoded by families of related genes. GNB1 encodes a beta subunit. Beta subunits are vital regulators of alpha subunits, as well as of certain signal transduction receptors and effectors. G proteins are involved as a modulator or transducer in numerous transmembrane signaling systems. The beta and gamma chains are necessary for the GTPase activity, for replacement of GDP by GTP, and for G protein-effector interaction.
