In membranes from SH-SY5Y human neuroblastoma cells differentiated with retinoic acid,
the mu-selective agonist Tyr-D-Ala-Gly-N-Me-Phe-Gly-ol (DAMGO) inhibited cAMP formation …

A direct interaction of alpha beta gamma trimeric GTP binding proteins (G proteins; G0 and
Gs) with nucleoside diphosphate kinase (NDP kinase) was investigated with …

Gαo, the most abundant G protein in mammalian brain, occurs at least in two subforms, ie,
Gαo1 and Gαo2, derived by alternative splicing of the mRNA. A third Gαo1-related isoform …

G-proteins are important mediators of hormonal inhibition of insulin secretion. To
characterize the pertussis toxin–sensitive substrates present in HIT cell membranes, we …

Three distinct G-protein alpha o-subtypes, ie alpha o1, alpha o2 and a newly observed
'alpha o3', are present in membranes of mammalian brain, each appearing as two isoforms …

Fluorescence energy transfer [cf. Förster, T.(1948) Ann. Phys. 6, 55–75] was tested for its
suitability to study quantitative interactions of subunits of Go with each other and these …

So far three splice variants of the α o-gene coding for two α o proteins have been identified
by molecular cloning, and the corresponding proteins purified. In the present study subtype …

The γ subunit composition of the major bovine brain GO and G i proteins (G OA, G OB, G OC,
G i1, and G i2) was characterized using antibodies against specific γ isoforms. Each of the …

Recent information obtained, mainly by recombinant cDNA technology, on structural
heterogeneity of hormone and transmitter receptors, of GTP‐binding proteins (G‐proteins) …

We have previously identified two isoforms of Go alpha in membranes of N1E-115
neuroblastoma cells, using an antibody raised against the purified Go alpha subunit; one …
