Dual regulation by G proteins of agonist-dependent phosphorylation of muscarinic acetylcholine receptors.

abstract：:To investigate additional functions of the T cell adaptor, Src homology 2 (SH2) domain-containing leukocyte protein of 76 kD (SLP-76), we performed a yeast two-hybrid assay using the N-terminal region of SLP-76 fused with the kinase domain of Syk. By screening a human leukemia cDNA library, we identified the p85 subun...
