Tandem phosphorylation of serines 221 and 318 by protein kinase cdelta coordinates mrna binding and nucleocytoplasmic shuttling of hurstabilization of mrna by the ubiquitous rna binding protein human antigen r (hur), a member of the embryonic lethal abnormal vision (elav) protein family, requires canonical binding to au-rich element (are)-bearing target mrna and export of nuclear hur-mrna complexes to the cytoplasm. In human mesangial cells (hmc) both processes are induced by angiotensin ii (angii) via protein kinase cdelta (pkcdelta)-triggered serine phosphorylation of hur.

Endocytosis of ligand-activated receptors requires dynamin-mediated GTP hydrolysis, which is regulated by dynamin self-assembly. Here, we demonstrate that phosphorylation of dynamin I by c-Src induces its self-assembly and increases its GTPase activity. Electron microscopic analyses reveal that tyrosine-phosphorylated dynamin I spontaneously self-assembles into large stacks of rings. Tyrosine 597 was identified as being phosphorylated both in vitro and in cultured cells following epidermal growth factor receptor stimulation.

Sprouty-related, EVH1 domain-containing (SPRED) proteins negatively regulate RAS/mitogen-activated protein kinase (MAPK) signaling following growth factor stimulation. This inhibition of RAS is thought to occur primarily through SPRED1 binding and recruitment of neurofibromin, a RasGAP, to the plasma membrane. Here, we report the structure of neurofibromin (GTPase-activating protein [GAP]-related domain) complexed with SPRED1 (EVH1 domain) and KRAS. The structure provides insight into how the membrane targeting of neurofibromin by SPRED1 allows simultaneous interaction with activated KRAS.

In HEK293 cells, transfected with the Ca2+ channel protein TRPV6, Ca2+ influx is increased and TRPV6 is tyrosine phosphorylated following addition of the tyrosine phosphatase inhibitor|PTP1B interacts with the N-terminal domain of TRPV6 within a region of amino acids 1-191 as shown by co-immunoprecipitation, bimolecular fluorescence complementation and the yeast 2-hybrid system. Point mutation of both tyrosines 161 and 162 in the TRPV6 protein abolishes the DMHV-effect on Ca2+ influx and tyrosine phosphorylation by Src. Single mutations of Y161 or Y162 shows that each of both tyrosines alone is sufficient for the DMHV-effect. We conclude that phosphorylation/dephosphorylation of tyrosines in position 161 and 162 is essential for regulation of Ca2+ influx through TRPV6 Ca2+ channels in HEK293 cells.

We have identified two novel proteins that interact specifically with the C-terminal repression domain of Interferon Regulatory Factor-2 (IRF-2). These proteins, which we term IRF-2 binding proteins 1 and 2 (IRF-2BP1 and IRF-2BP2, the latter having two splicing isoforms, A and B), are nuclear proteins, and have the properties of IRF-2-dependent transcriptional co-repressors that can inhibit both enhancer-activated and basal transcription in a manner that is not dependent upon histone deacetylation.

Activation of Stat1 and Stat3 by FGFR derivatives. Lysates of 293T cells transfected as indicated were analysed by Western blotting using Phospho-Stat1 (Y701) antisera (top) or Stat1 antisera (bottom). (b) The same lysates in (a) were re-examined for phosphorylated Stat3 by Western blotting with Phospho-Stat3 (Y705) (top). all three FGFR family members examined here are able to lead to Stat activation. Expression of the 'TDII-like' derivatives of FGFR1, FGFR3, and FGFR4, as well as myrR1-WT, led to phosphorylation of both Stat1 and Stat3.
