Protein levels of various Gβ alleles. Cells
(2 × 106) of wild type (lane 1), gβ−
(lane 2), SN1 (lane 3), SN2 (lane 4), SN3 (lane 5), SN4 (lane 6), SN5
(lane 7), and SN6 (lane 8) were harvested, solubilized in a gel loading
buffer, analyzed by SDS-PAGE, and subjected to immunoblot
using the specific Gβ antiserum.
