Gnb5 - G protein subunit beta 5

Enables GTPase activating protein binding activity. Predicted to be involved in several processes, including dopamine receptor signaling pathway; negative regulation of voltage-gated calcium channel activity; and positive regulation of GTPase activity. Predicted to act upstream of or within dark adaptation and light adaption. Located in cell body and cytosol. Part of protein-containing complex. Human ortholog(s) of this gene implicated in intellectual developmental disorder with cardiac arrhythmia. Orthologous to human GNB5 (G protein subunit beta 5).
