Protein attributes

Sequence length	340 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

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.
Subunit structure	G proteins are composed of 3 units, alpha, beta and gamma.
Sequence similarities	Belongs to the WD repeat G protein beta family. Contains 7 WD repeats.
