## Abstract The signal‐transduction system involving α‐adrenoceptors, which controls the aggregation of melanosomes, was investigated in the melanophores of the black‐moor goldfish, __Carassius auratus__. The order of effectiveness of α‐subtype‐specific agonists and antagonists indicated that the

## Abstract **Background:** Rab3A, a member of the Rab3 small G protein family, regulates Ca^2+^‐dependent exocytosis of neurotransmitter. The cyclical activation and inactivation of Rab3A are essential for the Rab3A action in exocytosis. GDP‐Rab3A is activated to GTP‐Rab3A by Rab3 GDP/GTP exchange
The possible regulation of guinea pig enterocyte ion channels by GTP-binding proteins has been investigated by using the whole-cell recording mode of the patch-clamp technique and non-hydrolysable analogues of GTP. The main K + currents in these cells are mediated by inwardlyrectifying K + channels.
