STAT3 signalling is required for leptin regulation of energy balance but not reproduction
Secretion of leptin from adipocytes communicates body energy status to the brain by activating the leptin receptor long form (LRb). LRb regulates energy homeostasis and neuroendocrine function; theExpand

The 'Shp'ing news: SH2 domain-containing tyrosine phosphatases in cell signaling.
Src homology-2 (SH2) domain-containing phosphatases (Shps) are a small, highly conserved subfamily of protein-tyrosine phosphatases, members of which are present in both vertebrates andExpand

Solubilization and purification of enzymatically active glutathione S-transferase (pGEX) fusion proteins.
The pGEX glutathione S-transferase (GST) fusion protein system is used extensively for high level expression and rapid purification of fusion proteins from bacterial and eukaryotic cell lysates.Expand

Mathematical models of protein kinase signal transduction.
We have developed a mathematical theory that describes the regulation of signaling pathways as a function of a limited number of key parameters. Our analysis includes linear kinase-phosphataseExpand

PTP1B regulates leptin signal transduction in vivo.
Mice lacking the protein-tyrosine phosphatase PTP1B are hypersensitive to insulin and resistant to obesity. However, the molecular basis for resistance to obesity has been unclear. Here we show thatExpand

Germline gain-of-function mutations in SOS1 cause Noonan syndrome
Noonan syndrome, the most common single-gene cause of congenital heart disease, is characterized by short stature, characteristic facies, learning problems and leukemia predisposition.Expand

Increased Energy Expenditure, Decreased Adiposity, and Tissue-Specific Insulin Sensitivity in Protein-Tyrosine Phosphatase 1B-Deficient Mice
ABSTRACT Protein-tyrosine phosphatase 1B (PTP-1B) is a major protein-tyrosine phosphatase that has been implicated in the regulation of insulin action, as well as in other signal transductionExpand

Shp2 regulates SRC family kinase activity and Ras/Erk activation by controlling Csk recruitment.
The protein-tyrosine phosphatase Shp2 plays an essential role in growth factor and integrin signaling, and Shp2 mutations cause developmental defects and/or malignancy. Previous work has placed Shp2Expand
