Human gamma-crystallins are long-lived, unusually stable proteins of the eye lens exhibiting duplicated, double Greek key domains. The lens also contains high concentrations of the small heat shock chaperone alpha-crystallin, which suppresses aggregation of model substrates in vitro. Mature-onset cataract is believed to represent an aggregated state of partially unfolded and covalently damaged crystallins. The alphaB-crystallin oligomers formed long-lived stable complexes with their gammaD-crystallin substrates. These in vitro results provide support for protein unfolding/protein aggregation models for cataract, with alpha-crystallin suppressing aggregation of damaged or unfolded proteins through early adulthood but becoming saturated with advancing age.

Our genetic analysis indicates that Foxo1 is an effector of Irs2 signaling in pancreatic β cells. Foxo1 inactivation leads to increased Pdx1 expression and β cell proliferation. Since Foxo1 is expressed in a subset of cells embedded within pancreatic ducts, we propose that, in quiescent duct-associated cells that are not committed to a β cell fate, Foxo1 acts as a transcriptional brake on Pdx1. We propose the following mechanism of Foxo1 regulation: small quantities of insulin are released in the pancreatic duct (31), where they activate signaling (32) in the Foxo1-positive duct cell subset, leading to Foxo1 nuclear exclusion and Pdx1 expression.

Upon ligand binding, IL-2R , IL-6R or LeptinR , IFN-_R , IFN-_R and PRLR or growth hormone (GH) receptor associated JAKs become activated. These JAKs mediate phosphorylation of specific tyrosine residues and recruit STATs. Activated STATs are released from the receptor and translocate to the nucleus. PTP1B dephosphorylates JAK2, TYK2 and STAT5 . The 45-kDa form of TC-PTP was shown to dephosphorylate JAK1 and JAK3 as well as STAT1, STAT3 and STAT5.

Tyrosine at residue 1,068 of the EGFR is proposed to be one of the principal phosphorylation sites and Grb2-binding sites stimulated by growth hormone via Jak2. Our results indicate that the role of EGFR in signalling by growth hormone is to be phosphorylated by Jak2, thereby providing docking sites for Grb2 and activating MAP kinases and gene expression, independently of the intrinsic tyrosine kinase activity of EGFR.

Pre- and postsynaptic plasma membranes are always precisely aligned, and are separated by a synaptic cleft of ~20 nm. The cleft contains an undefined proteinaceous material in the middle, and is presumably bridged by synaptic cell-adhesion molecules such as Nrxns and Nlgns that align the pre- and postsynaptic elements and mediate trans-synaptic signaling.|Nlgns bind to both alpha- and beta-Nrxns with nanomolar affinities; binding involves the sixth LNS-domain of alpha-Nrxns which corresponds to the only LNS-domain of beta-Nrxns52. The binding affinities differ characteristically between various pairs of Nlgns and Nrxns, and are controlled by alternative splicing of both Nrxns and Nlgns (Figure 1c)

One of the most well studied activators of CCND1 transcription is β-catenin, which could be actived by AKT signalling to inducing G1/S transition. When β-catenin is translocated from the cytoplasm to the nucleus, it forms a complex with the ternary complex factor (TCF) and/or lymphoid enhancer-binding factor (LEF) and stimulates cyclin D1 gene transcription (Fig. 4C).In agreement with the data described above, a chromatin immunoprecipitation (ChIP) assay confirmed that TNC regulates the binding of β-catenin to the TCF/LEF-binding site in the CCND1 promoter (Fig. 4C). Additionally, the β-cateninbinding activity with respect to the CCND1 promoter was much higher in TNC-overexpression PANC-1 cells than in the vector controls.

ZNF804A has been implicated in susceptibility to schizophrenia by several genome-wide association studies (GWAS), follow-up association studies and meta-analyses. ZNF804A was identified as a schizophrenia-associated gene by GWAS and was predicted to play a role in DNA binding and transcription To identify the genes that are affected by ZNF804A, we manipulated the expression of the ZNF804A protein in HEK293 human embryonic kidney cell lines and performed a cDNA microarray analysis followed by qPCR. We found that ZNF804A-overexpression up-regulated four genes (ANKRD1, INHBE, PIK3AP1, and DDIT3) and down-regulated three genes (CLIC2, MGAM, and BIRC3).

For each receptor, we probed chimeric G alpha subunit activation via a transforming growth factor-alpha (TGF alpha) shedding response in HEK293 cells lacking endogenous Gq/11- and G12/13- signaling. | We defined positive coupling if any member of the subfamily scored LogRAi ≥ -1 and negative coupling if all of the members scored LogRAi < -1 (Figure 3A-B). ROC analysis gives AUC = 0.78 (Figure S4A) when considering high-confidence known coupling data and suggested a threshold of LogRAi ≥ -1.0 for defining true couplings. | The score associated to this interaction has a LogRAi ≥ -1.0.

This phosphorylation interdicts 14-3-3 binding, promotes foxo nuclear residence and transcriptional activity. The other major signaling modules that directly regulate the activity of the foxo factors include the stress-activated jun-n-terminal kinase (jnk), the mammalian ortholog of the ste20-like protein kinase (mst1), and the deacetylase sirt1.

Matrix Gla protein suppresses cardiovascular calcification, and brain-expressed Gas 6 promotes neural differentiation [29]. GGCX is an enzyme that converts glutamic acid (Glu) residues to Gla residues, so that the Gla-containing proteins can exert various physiological actions such as blood coagulation and bone formation.
