Tyrosine 55-63 leptin Mus musculus 0-6 20360640-5 2010 RESULTS: SH2B1 dramatically enhanced the leptin-stimulated tyrosine phosphorylation of JAK2 and IRS2 in HEK293 cells stably expressing LRb (HEK239(LRb)). Tyrosine 59-67 leptin Mus musculus 41-47 20068132-2 2010 Leptin binding to LepRb initiates signaling by activating the associated Janus kinase 2 (Jak2) tyrosine kinase, which promotes the phosphorylation of tyrosine residues on the intracellular tail of LepRb. Tyrosine 95-103 leptin Mus musculus 0-6 22685316-2 2012 Leptin"s actions are mediated by signaling events initiated by phosphorylation of tyrosine residues on the long form of the leptin receptor. Tyrosine 82-90 leptin Mus musculus 0-6 19524014-3 2009 We found that leptin increased Sam68 tyrosine-phosphorylation so decreasing its poly(U)-binding capacity. Tyrosine 37-45 leptin Mus musculus 14-20 10080923-0 1999 Tyrosine phosphorylation of STAT3 by leptin through leptin receptor in mouse metaphase 2 stage oocyte. Tyrosine 0-8 leptin Mus musculus 37-43 10080923-6 1999 Leptin at 15 ng/ml, the concentration observed in follicular fluid, caused tyrosine phosphorylation of STAT3 in mouse M2 stage oocytes. Tyrosine 75-83 leptin Mus musculus 0-6 9434783-1 1997 Leptin at 1-5 nM, the concentrations observed in obese subjects, caused an increase in the active form of mitogen-activated protein kinase (MAPK) that was accompanied by increased tyrosine phosphorylation of STAT-1 and STAT-3 in a mouse pancreatic beta cell line, MIN6. Tyrosine 180-188 leptin Mus musculus 0-6 33045434-12 2020 Compared to HSD2OB/OCY mice, leptin-resistant wild-type mice displayed attenuated sympathetic outflow, with reduced tyrosine hydroxylase expression in both the hypothalamus and thermogenic adipose tissues. Tyrosine 116-124 leptin Mus musculus 29-35 30269370-6 2019 In contrast, mutation of LepRb Tyr 985 , which blocks SHP2/SOCS3 recruitment to LepRb and contributes to leptin hypersensitivity, promoted increased femur bone density only in male mice, while marrow adiposity and bone growth were not affected. Tyrosine 31-34 leptin Mus musculus 105-111 19015522-0 2008 Tyrosine-dependent and -independent actions of leptin receptor in control of energy balance and glucose homeostasis. Tyrosine 0-8 leptin Mus musculus 47-53 19015522-3 2008 Here, we generated 2 knockin lines of mice expressing mutant leptin receptors with phenylalanine substitution for all 3 tyrosines (Y123F) or for Tyr(1138) alone (Y3F). Tyrosine 120-129 leptin Mus musculus 61-67 14698207-4 2003 Native murine leptin (1-147) enhanced aldosterone and corticosterone secretion from dispersed ZG and ZF/R cells, and similar effects were elicited by murine leptin fragment 116-130, and human leptin fragments 138-167, 150-167 and [Tyr] 26-39. Tyrosine 231-234 leptin Mus musculus 14-20 24024119-2 2012 Leptin binding to its receptor (LepR-b) promotes the tyrosine phosphorylation of three sites on LepR-b, each of which mediates distinct downstream signals. Tyrosine 53-61 leptin Mus musculus 0-6 22685316-2 2012 Leptin"s actions are mediated by signaling events initiated by phosphorylation of tyrosine residues on the long form of the leptin receptor. Tyrosine 82-90 leptin Mus musculus 124-130 22685316-4 2012 In this report, we assessed leptin receptor-mediated ERK activation, a pathway that was ablated in the l/l mouse through a mutation of the tyrosine 985 residue in the leptin receptor, to determine its role in host defense against bacterial pneumonia in vivo and in alveolar macrophage (AM) antibacterial functions in vitro. Tyrosine 139-147 leptin Mus musculus 28-34 22685316-4 2012 In this report, we assessed leptin receptor-mediated ERK activation, a pathway that was ablated in the l/l mouse through a mutation of the tyrosine 985 residue in the leptin receptor, to determine its role in host defense against bacterial pneumonia in vivo and in alveolar macrophage (AM) antibacterial functions in vitro. Tyrosine 139-147 leptin Mus musculus 167-173 21521753-3 2011 Leptin action is mediated by phosphorylation of several tyrosine residues on LepRb. Tyrosine 56-64 leptin Mus musculus 0-6 21124310-7 2011 Mutation of tyrosine 985 or 1138 in the intracellular domain of the leptin receptor, which mediates signaling through the SH2-containing tyrosine phosphatase/extracellular signal-regulated kinase (SHP2/ERK) and signal transducer and activator of transcription 3 (STAT3) pathways, respectively, demonstrated that both were important for mucosal protection.
