In osteoblasts, hormones such as prostaglandin E2 that activate protein kinase A increase the translocation of transcription factor CCAAT/enhancer binding protein (C/EBP ) from the cytoplasm to the nucleus where it rapidly induces IGF-I gene expression. In this study, we identified activation and suppression domains in C/EBP using native and heterologous gene promoter assay systems. We demonstr...

The RNA recognition motif (RRM), one of the most common RNA-binding domains, recognizes single-stranded RNA. A C-terminal helix that undergoes conformational changes upon binding is often an important contributor to RNA recognition. The N-terminal RRM of the U1A protein contains a C-terminal helix (helix C) that interacts with the RNA-binding surface of a beta-sheet in the free protein (closed ...

BACKGROUND HNF1A gene regulates liver-specific genes, and genes that have a role in glucose metabolism, transport, and secretion of insulin. HNF1A gene mutations are frequently associated with type 2 diabetes. HNF1A protein has three domains: the dimerization domain, the DNA-binding domain, and the trans-activation domain. Some mutations in the dimerization or DNA-binding domains have no influe...

introduction: normal homeostasis system has several inhibitor mechanisms in front of the amplifier’s natural clotting enzyme to prevent fibrin clots in the vessels. the main inhibitors of coagulation pathway are antithrombin (at), protein c and protein s. patients with hereditary deficiency of coagulation inhibitors are susceptible to venous thromboembolism (vte). one of the major clinical mani...

host innate immunity can affect the clinical outcomes of helicobacter pylori infection, including gastritis, gastric ulcer, gastric adenocarcinoma, and malt lymphoma. nucleotide binding oligomerization domain (nod)-1 and -2 are two molecules of innate immunity which are involved in the host defense against h. pylori . this study aimed to evaluate the effect of the expression level of nod1 and n...
