In the C1 complex (C1qr2s2), this specific protease activity is exhibited by C1s after activation of this enzyme by C1r. When C4 is activated, its reactive thiol ester is exposed and C4b binds covalently to nearby amino or hydroxyl groups.

Dephosphorylation of the threonine residue by pp2a (protein serine/threonine phosphatase 2a) decreased erk8 activity by over 95% in vitro, whereas complete dephosphorylation of the tyrosine residue by ptp1b (protein tyrosine phosphatase 1b) decreased activity by only 15-20%

In this study, we demonstrate that SARS-associated coronavirus (SARS-CoV) nucleocapsid (N) protein potentiates transforming growth factor-beta (TGF-beta)-induced expression of plasminogen activator inhibitor-1 but attenuates Smad3/Smad4-mediated apoptosis of human peripheral lung epithelial HPL1 cells. The promoting effect of N protein on the transcriptional responses of TGF-beta is Smad3-specific. N protein associates with Smad3 and promotes Smad3-p300 complex formation while it interferes with the complex formation between Smad3 and Smad4. These findings provide evidence of a novel mechanism whereby N protein modulates TGF-beta signaling to block apoptosis of SARS-CoV-infected host cells and meanwhile promote tissue fibrosis.

In innate immunity, nearly all Toll-like receptors (TLRs), as well as the receptors of the interleukin 1 (IL-1) family of cytokines, initiate signaling by recruiting the adaptor protein MyD88. This is followed by the interaction of IL-1-receptor (IL-R)-associated kinase 4 (IRAK4) with MyD88 and then the interaction of other IRAK family members with IRAK4, to form an oligomeric complex, termed the Myddosome (8, 9). IRAK1 and IRAK2 can then interact with TRAF6 (10, 11) and induce TRAF6 dimerization (12), which triggers the activation of its E3 ligase activity

We evaluated the putative role of sgk1 in the modulation of glut4. Coexpression of the kinase along with glut4 in xenopus oocytes stimulated glucose transport. The enhanced glut4 activity was paralleled by increased transporter abundance in the plasma membrane. Disruption of the sgk1 phosphorylation site on glut4 ((s274a)glut4) abrogated the stimulating effect of sgk1. In summary, sgk1 promotes glucose transporter membrane abundance via glut4 phosphorylation at ser274.

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.
