HMDB Protein ID HMDBP08399
Secondary Accession Numbers
  • 14111
Name Guanine nucleotide-binding protein G(I)/G(S)/G(T) subunit beta-2
  1. G protein subunit beta-2
  2. Transducin beta chain 2
Gene Name GNB2
Protein Type Unknown
Biological Properties
General Function Involved in GTPase activity
Specific Function Guanine nucleotide-binding proteins (G proteins) are involved as a modulator or transducer in various transmembrane signaling systems. The beta and gamma chains are required for the GTPase activity, for replacement of GDP by GTP, and for G protein- effector interaction
