The dominant insulin-stimulated ribosomal protein S6 kinase activity was purified to near homogeneity from insulin-treated 32P-labeled rat H4 hepatoma cells and found to copurify with a 70-kDa 32P-labeled polypeptide.

Insulin treatment increases the 32P content of the immunoprecipitated 70-kDa S6 kinase polypeptide 3- to 4-fold over basal levels; 32P-labeled serine, some 32P-labeled threonine, but no 32P-labeled tyrosine are detected after partial acid hydrolysis.

The phosphatase 2A-deactivated 70-kDa S6 kinase is neither reactivated nor phosphorylated by partially purified insulin-stimulated microtubule-associated protein 2 kinase, in experiments where Xenopus S6 kinase II undergoes phosphorylation and partial reactivation.

|
Thus insulin activates the 70-kDa S6 kinase by promoting phosphorylation of specific serine/threonine residues on the enzyme polypeptide, probably through activating an as-yet-unidentified serine/threonine protein kinase distinct from microtubule-associated protein 2 kinase.

The C825T single nucleotide polymorphism (SNP) in the guanine nucleotide-binding protein, beta polypeptide 3 ( GNB3) gene gives rise to a splice variant, GNB3s that has enhanced G protein activation and signal transduction activity.

We genotyped 11 single nucleotide polymorphisms for 10 obesity candidate genes including adrenergic beta-2-receptor surface, adrenergic beta-3-receptor surface, angiotensinogen, fat mass and obesity associated gene, guanine nucleotide binding protein beta polypeptide 3 (GNB3), interleukin 6 receptor, proprotein convertase subtilisin/kexin type 1 (PCSK1), uncoupling protein 1, uncoupling protein 2, and uncoupling protein 3.

Single-locus analyses showed significant main effects of the GNB3 and PCSK1 genes on the risk of T2D among the nonobese group (p = 0.002 and 0.047, respectively).

|
Further, interactions involving GNB3 and PCSK1 were suggested among the nonobese population using the generalized multifactor dimensionality reduction method (p = 0.001).

In addition, interactions among angiotensinogen, fat mass and obesity associated gene, GNB3, and uncoupling protein 3 genes were found in a significant four-locus generalized multifactor dimensionality reduction model among the obese population (p = 0.001).
