Is β-arrestin-2 expressed in human prostate smooth muscle and a binding partner of α1A-adrenoceptors?
With β-arrestin-2, we identified a new binding partner of the α1A-adrenoceptor in human prostate smooth muscle. Binding of β-arrestin-2 may be involved in posttranslational regulation of prostate α1A-adrenoceptors.
These results suggested that mNanog expression induces dorsal mesoderm by regulating both Activin/nodal signaling and BMP signaling in Xenopus. This finding highlights the possibly novel function for mNanog in stimulating the endogenous gene network in Xenopus mesoderm formation.
