The alpha 2B adrenergic receptor of undifferentiated neuroblastoma x glioma hybrid NG108-15 cells, interacts directly with the guanine nucleotide binding protein, Gi2.

In membranes of undifferentiated neuroblastoma x glioma hybrid cell line NG108-15, the apparent specific binding of [3H]yohimbine measured in the presence of 1 microM noradrenaline, was increased substantially by the presence of the poorly hydrolysed analogue of GTP, guanylyl-imidodiphosphate (Gpp[NH]p) or by preincubation of membranes with antibodies against the C-terminal decapeptide of the alpha subunit of the G-protein Gi2. Such an effect was not produced by antibodies against the equivalent region of Go alpha Gi3 alpha or Gs alpha or from non-immune serum. By contrast, total specific binding of [3H]yohimbine was not modified by co-incubation with Gpp[NH]p or by preincubation with the antibodies from any of the anti-G protein antisera. These results demonstrate a direct interaction of the alpha 2B adrenergic receptor of NG108-15 cells with Gi2.[1]
