Altered emotional behaviors in the diabetes mellitus OLETF type 1 congenic rat.

GPR10 is a G-protein-coupled receptor expressed in thalamic and hypothalamic brain regions, including the reticular thalamic nucleus (RTN) and periventricular nucleus (Pev), and the endogenous ligand for this receptor, prolactin-releasing peptide (PrRP), has demonstrated regulatory effects on the stress response. We produced a congenic rat by introducing the Dmo1 allele from the OLETF rat which encodes the amino acid sequences of GPR10 with a truncated NH2-terminus, into the Brown-Norway background. Using receptor autoradiography, we determined a lack of specific [125I]PrRP binding in the RTN and Pev of these mutant rats compared to the control rats.

Isolation and identification of novel ADP-ribosylated proteins from Streptomyces coelicolor A3(2).

An important role of protein ADP-ribosylation in bacterial morphogenesis has been proposed (J. Bacteriol. 178, 3785-3790; 178, 4935-4941).
