The 14-3-3 Proteins: Gene,Gene Expression,and Function

14-3-3 Proteins were discovered by Moore and Perez in the soluble extract of bovine brain. These proteins are highly abundant in the brain. In this review 14-3-3 cDNA cloning, nucleotide sequence of 14-3-3 cDNA, the structure of 14-3-3 gene and 14-3-3 gene expression, in situ hybridization of 14-3-3 mRNA in the brain, the function and regulation of 14-3-3 protein, the binding of 14-3-3 protein to other proteins, the effects of 14-3-3 protein on the binding of a protein to other proteins, and the effect on protein kinase, etc., are concisely described. From the recent rapid development of proteom technology, markedly more target proteins of 14-3-3 protein should be discovered.     

The synthesis of 13- - - -15, 16-dihydroxyprostaglandins

Both pairs of -ll-desoxy- and -13- - -15, 16-dihydroxyprostaglandins have been synthesized via 1,4-conjugate additions of an appropriately functionalized -vinyl cuprate to the requisite cyclopentenone. These prostaglandin analogs are considerably less potent than PGE₂ as gastric secretion inhibitors or as bronchodilators.
