Description
Product Characteristics:
Heterotrimeric guanine nucleotide binding proteins (G proteins), which integrate signals between receptors and effector proteins, are composed of an alpha, a beta, and a gamma subunit. GNB1 is a beta subunit. The beta and gamma chains are required for the GTPase activity, for replacement of GDP by GTP, and for G protein-effector interaction.
Subcellular location: Cytoplasm, Cell membrane
Synonyms: Beta subunit signal transducing proteins GS/GI, G protein beta 1 subunit, GBB1, Guanine nucleotide binding protein beta 1 subunit, Transducin beta chain 1, GBB1_HUMAN.
Target Information: Heterotrimeric guanine nucleotide-binding proteins (G proteins), which integrate signals between receptors and effector proteins, are composed of an alpha, a beta, and a gamma subunit. These subunits are encoded by families of related genes. This gene encodes a beta subunit. Beta subunits are important regulators of alpha subunits, as well as of certain signal transduction receptors and effectors. This gene uses alternative polyadenylation signals.
