Tetratricopeptide repeat domain 9A (TTC9A) is a target gene of estrogen and progesterone. It is over-expressed in breast cancer. However, little is known about the physiological function of TTC9A. The objectives of this study were to establish a Ttc9a knockout mouse model and to study the consequence of Ttc9a gene inactivation. The Ttc9a targeting vector(More)
Expression under the control of the mouse transferrin promoter of a transgene encoding a soluble secreted derivative of the ectodomain of the human insulin receptor in transgenic mice results in the accumulation of this high-affinity insulin-binding protein in the plasma. Alterations of glucose homeostasis are observed including postabsorptive hyperglycemia(More)
Monoclonal antibody (mAb) 5B4 recognizes a developmentally regulated membrane glycoprotein (Mr approximately 185,000-255,000) expressed on sprouting neurons. The amino acid sequence deduced from lambda gt11 cDNA clones encoding the transmembrane and cytoplasmic domains of the 5B4 antigen is co-linear with that of chick NCAM-ld. The significant level of(More)
DNA analysis showed the presence of plasmids in all 29 strains of mesophilic lactic streptococci. Their number ranged from 1 to 9 and their molecular weight extended from 1.8 to 45 megadaltons (Md). Comparison of the plasmid profiles from 9 strains of Streptococcus lactis, 3 strains of S. lactis ssp. diacetylactis and from their Lac-,Prt-variants was(More)
The human insulin receptor (IR) is a transmembrane glycoprotein, whose cytoplasmic domain contains an insulin-activated protein-tyrosine kinase (EC By the use of an appropriately engineered baculovirus expression vector, a soluble cytoplasmic derivative of this domain was expressed in the insect cell line Spodoptera frugiperda (Sf9). At 24 to 48(More)
Monoclonal antibody 5B4 recognizes a carboxy-terminal epitope common to large (approximately 180 kDa) and short (approximately 140 kDa) forms of neural cell adhesion molecules (NCAM-ld and NCAM-sd, respectively). The deduced primary sequence of rat brain 5B4/NCAM-ld predicts a large cytoplasmic domain (390 amino acids, Mr 39,284) of striking amino acid(More)
A mutant human insulin receptor with a carboxyl-terminal deletion of 69 amino acids (proreceptor residues 1287-1355) is expressed as a stable protein in transiently transfected COS cells. We find that in intact cells this mutant is phosphorylated in an insulin-dependent manner on core tyrosines 1158, 1163 and 1163. As expected, the carboxyl-terminal(More)
