TGFbeta signaling is initiated when the type I receptor phosphorylates the MAD-related protein, Smad2, on C-terminal serine residues. This leads to Smad2 association with Smad4, translocation to the nucleus, and regulation of transcriptional responses. Here we demonstrate that Smad7 is an inhibitor of TGFbeta signaling. Smad7 prevents TGFbeta-dependent(More)
Rod-cone dysplasia type 2 (rcd2) is an autosomal recessive disorder that segregates in collie dogs. Linkage disequilibrium and meiotic linkage mapping were combined to take advantage of population structure within this breed and to fine map rcd2 to a 230-kb candidate region that included the gene C1orf36 responsible for human and murine rd3, and within(More)
Cholesteryl ester transfer protein (CETP) mediates the exchange of phospholipids and neutral lipids between the plasma lipoproteins, and plays an important role in high density lipoprotein (HDL) metabolism. While there are reports of low-level CETP secretion from cultured cells, the lack of a good model cell line has hampered the detailed study of CETP(More)
Human protein C is a vitamin K-dependent plasma glycoprotein that circulates as an inactive zymogen. At the endothelial cell surface, thrombin in complex with the integral membrane protein thrombomodulin converts protein C to its active form by specific cleavage of an activation peptide. The activated form of protein C has potent anticoagulant activity as a(More)
This report describes the complete nucleotide sequence of human reovirus (Dearing strain) genome segment S3. Previous studies indicated that this RNA encodes the major non-structural viral polypeptide sigma NS, a protein that binds ssRNAs (Huisman & Joklik, Virology 70, 411-424, 1976) and has a poly(C)-dependent poly(G) polymerase activity (Gomatos et al.,(More)
