Recent molecular cloning studies have established the existence of a third rat galanin receptor subtype, GalR3, however its precise distribution in the mammalian central nervous system (CNS) is not well established. In the present study, we examined the regional and cellular distribution of GalR3 mRNA in the CNS of the rat by in situ hybridization. Our(More)
Several peptide fragments are produced by proteolytic cleavage of the opioid peptide precursor proenkephalin A, and among these are a number of enkephalin fragments, in particular bovine adrenal medulla peptide 22 (BAM22). These peptide products have been implicated in diverse biological functions, including analgesia. We have cloned a newly identified(More)
As part of an ongoing investigation into the organization and regulation of the flavonoid biosynthetic pathway, two Arabidopsis thaliana expressed sequence tag (EST) clones (153O10T7 and YAY780) with high homology to leucoanthocyanidin dioxygenase (LDOX) or flavonol synthase (FLS) were identified. EST YAY780 was sequenced and found to encode a protein 49 to(More)
A genomic clone encoding flavanone 3-hydroxylase (F3H) was isolated from Arabidopsis thaliana. The deduced amino acid sequence is 72 to 94% identical to all previously reported F3H proteins. Low-stringency DNA blot analysis indicated that F3H is encoded by a single gene in Arabidopsis. The F3H locus was mapped to the bottom of chromosome 3 and therefore(More)
Polyclonal antibodies were developed against the flavonoid biosynthetic enzymes, CHS, CHI, F3H, FLS, and LDOX from Arabidopsis thaliana. These antibodies were used to perform the first detailed analysis of coordinate expression of flavonoid metabolism at the protein level. The pattern of flavonoid enzyme expression over the course of seedling development(More)
An enormous variety of metabolic processes are characterized by enzyme complexes, which are likely to play important roles in directing the efficient operation and specificity of cellular metabolism. In many cases membranes or cytoskeletal elements provide scaffolding for these highly ordered assemblies of enzymes. Biochemical and immunocytochemical studies(More)
