The human G protein beta4 subunit: gene structure, expression, Ggamma and effector interaction.
The aim of this study was the characterization of the human Gbeta4 subunit of heterotrimeric G proteins. Human Gbeta4 is widely expressed. Its gene is located on chromosome 3 with a genomic structure indistinguishable from that of the genes of Gbeta1 to Gbeta3, but entirely different from Gbeta5. In vitro ... translation co-precipitation analyses revealed that Gbeta4 can form stable dimers with Ggamma1, Ggamma2, Ggamma3, Ggamma4, Ggamma5, Ggamma7, Ggamma10, Ggamma11, Ggamma12, and Ggamma13, dimers which were also able to stimulate phospholipase beta2.
