Paternal versus maternal transmission of a stimulatory G-protein alpha subunit knockout produces opposite effects on energy metabolism

Heterozygous disruption of Gnas, the gene encoding the stimulatory G-protein alpha subunit (G(s)alpha), leads to distinct phenotypes depending on whether the maternal (m-/+) or paternal (+/p-) allele is disrupted. G(s)alpha is imprinted, with the maternal allele preferentially expressed in adipose t...
