Disease relevance of YWHAZ

• Here we describe the cloning and expression of a gene encoding FAS from a bovine brain cDNA library and demonstrate that purified recombinant FAS produced in Escherichia coli activates ExoS in a defined cell-free system [1].
• It also activates exoenzyme S of Pseudomonas aeruginosa as does bovine brain factor activating exoenzyme S (FAS), which is itself a member of 14-3-3 proteins [2].

High impact information on YWHAZ

• The deduced amino acid sequence of FAS shows that the protein (245 residues, calculated molecular mass 27,743 Da) belongs to a highly conserved, widely distributed eukaryotic protein family, collectively designated as 14-3-3 proteins [1].
• These data suggest that CBX limits FAS in adipose tissue of cattle [3].
• FAS did not increase until day 3 of refeeding when energy intake was above maintenance, then returned to normal by 14 days [3].
• Rates of acetate incorporation into fatty acids (FAS), activities of acetyl CoA carboxylase (CBX), glucose-6-phosphate dehydrogenase, 6-phosphogluconate dehydrogenase, and NADP:isocitrate dehydrogenase, and plasma free fatty acids (FFA) and plasma acetate were determined [3].
• The FAS are laurate, myristate, and palmitate [4].

Biological context of YWHAZ

• The 110 kDa polypeptide and its fragments were phosphorylated by a nuclear envelope kinase and this phosphorylation was inhibited by a monoclonal antibody against protein kinase C and by a specific protein kinase C inhibitor obtained from bovine brain [5].
