- G protein beta 4 subunit
- GNB 4
FunctionGuanine 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.
Tissue specificityStrongly expressed in lung and placenta, whereas it is weakly expressed in brain and heart.
Sequence similaritiesBelongs to the WD repeat G protein beta family.
Contains 7 WD repeats.
