In this study, we found that USP21 is an important deubiquitinating enzyme for STING and that it negatively regulates the DNA virus-induced production of type I interferons by hydrolyzing K27/63-linked polyubiquitin chain on STING. HSV-1 infection recruited USP21 to STING at late stage by p38-mediated phosphorylation of USP21 at Ser538. I

6PGD is phosphorylated at tyrosine (Y) 481 by Src family kinase Fyn. This phosphorylation enhances 6PGD activity by increasing its binding affinity to NADP+ and therefore activates the PPP for NADPH and ribose-5-phosphate, which consequently detoxifies intracellular reactive oxygen species (ROS) and accelerates DNA synthesis.

Dephosphorylation results in limited expression and binding of the 98 kDa Elf-1 form to the CD3zeta and FcRgamma promoters.

Recent reports show that in mice the microbiome, comprising commensal microorganisms that colonize body surfaces, promotes a partial and low-grade M1-like phenotype in macrophages throughout the body, including those in lymphoid organs (119, 120). This M1-like priming of macrophages induces chromatin remodeling with increased H3K4me3 marks at Ifnb, Il6, and Tnf promoters, which is associated with increased binding of NF-κB p65, IRF3, and Pol II upon cell stimulation

PTPRG activation by the P1-WD peptide affected the tyrosine phosphorylation of several signaling molecules. Data analysis identified 31 molecules whose phosphorylation was modified in a statistically significant manner (Table I). inhibition of ABL1, BMX, BTK, DAB1, ITGB1, JAK2, KDR, KIT, LIMK1, MET, PDGFRB, SHC1, and VCL correlates with tyrosine dephosphorylation. In contrast, SRC inhibition correlates with hyperphosphorylation of the inhibitory Tyr530 residue and with dephosphorylation of the activatory Tyr419. Moreover, CDK2 and CTTN inhibition correlates with a hyperphosphorylation of the inhibitory Tyr15 and Tyr470, respectively. In contrast, a subgroup of 13 proteins, including BLNK, DOK2, ERBB2, GRIN2B, INSR, PDGFRA, PRKCD, PXN, STAT1, STAT2, STAT3, STAT5A, and ZAP70, appears to be activated by PTPRG activity.

Nuclear run-on studies confirmed that the GLUT1 transcriptional rate is elevated by c-Myc.

Here, we demonstrate the partial purification of a protein kinase that phosphorylates the type iialpha pip kinase at a single site unique to that isoform - ser304. This kinase was identified as protein kinase ck2 (formerly casein kinase 2). Mutation of ser304 to aspartate to mimic its phosphorylation had no effect on pip kinase activity, but promoted both redistribution of the green fluorescent protein (gfp)-tagged enzyme in hela cells from the cytosol to the plasma membrane, and membrane ruffling.

Many potential substrates of LNX E3s were identified. Eight of the nine selected candidates were ubiquitinated in vitro, and two novel endogenous substrates, PDZ-binding kinase (PBK) and breakpoint cluster region protein (BCR), were confirmed in vivo.

EphA2 associates with claudin-4 via their extracellular domains. This association, in turn, leads to phosphorylation of the cytoplasmic carboxyl terminus of claudin-4 at Tyr-208. The tyrosine phosphorylation of claudin-4 attenuates association of claudin-4 with ZO-1, decreasing integration of claudin-4 into sites of cell-cell contact and enhancing paracellular permeability. These results indicate that EphA2 moderates the function of tight junctions via phosphorylation of claudin-4.
