The 1.8 A crystal structure of transducin alpha.GDP, when compared to that, of the activated complex with GTP-gamma S, reveals the nature of the, conformational changes that occur on activation of a heterotrimeric, G-protein alpha-subunit. Structural changes initiated by direct contacts, with the terminal phosphate of GTP propagate to regions that have been, implicated in effector activation. The changes are distinct from those, observed in other members of the GTPase superfamily.

== Function ==
 +
[https://www.uniprot.org/uniprot/GNAT1_BOVIN GNAT1_BOVIN] Guanine nucleotide-binding proteins (G proteins) are involved as modulators or transducers in various transmembrane signaling systems. Transducin is an amplifier and one of the transducers of a visual impulse that performs the coupling between rhodopsin and cGMP-phosphodiesterase.
