These neuropeptides, including gastrin-releasing peptide, neuromedin b, neurotensin, gastrin, cholecystokinin and arginine vasopressin bind seven transmembrane-spanning receptors that couple to heterotrimeric g proteins. Studies with human small cell lung cancer (sclc) cells support a requirement for balanced signaling through g(q) and g(12/13) proteins leading to intracellular ca2+ mobilization, pkc activation and regulation of the erk and jnk map kinase pathways.

Here, we provide evidence that Ariadne RBR E3 ubiquitin ligases such as TRIAD1 and HHARI can bind and be activated by CRL complexes. Whereas TRIAD1 specifically associates with CUL5–RBX2, HHARI is more promiscuous towards cullin types and associates with RBX1-associated cullins 1, 2, 3, and 4A. Interestingly, both TRIAD1 and HHARI show a strong preference for binding the neddylated form of the cullin. Our data suggest a novel function of NEDD8 in directing specific CRLs to Ariadne RBR ligases, which in turn exert influence on the levels of their cognate neddylated cullin.

Post-translational enhancement of ALDH2 activity can be achieved by serine/threonine phosphorylation by epsilon protein kinase C (epsilonPKC). |e identified S279 as a critical εPKC phosphorylation site in the activation of ALDH2. The critical catalytic site, cysteine 302 (C302) of ALDH2 is susceptible to adduct formation by reactive aldehyde, 4HNE, which readily renders the enzyme inactive. We show that phosphomimetic mutations of T185E, S279E and T412E confer protection of ALDH2 against 4HNE-induced inactivation, indicating that phosphorylation on these three sites by εPKC likely also protects the enzyme against reactive aldehydes.

To this end, we confirm that KDM3A, KDM4B, KDM4C, KDM5B, KDM5C, and KDM62 are direct targets of HIF-1a while extent the list of known targets to KDM2A, KDM2B, KDM4D, KDM5A, and KDM6A. The results demonstrated that majority of the KDMs were similarly induced (KDM2A, KDM2B, KDM3A, KDM4B, KDM4C, KDM4D, KDM5A, KDM5B, KDM5C, KDM6B, and KDM7A) or repressed (KDM NO66 and KDM1A) by both HIF-1a and HIF-2a.

Here we systematically quantified ligand-induced interactions between 148 GPCRs and all 11 unique G alpha subunit C-termini. 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.

ALK4 phosphorylated TTRAP in vitro (Fig. 6A). The band migrating at the position of TTRAP was excised and analyzed by LC-MS/MS. One TTRAP peptide was phosphorylated either on T88 and T92, or on T92 only (Fig. 6B).We tested in vivo phosphorylation of Strep-TTRAP by co-expression with mouse Alk4 in HEK293T cells, and affinity-purified TTRAP. In this preparation TTRAP-specific peptides were reproducibly found in both the singly (T92) and doubly phosphorylated form (T88/T92). mutant TTRAPT88A,T92A is not able to rescue the TtrapMO phenotype, suggesting that phosphorylation of Ttrap on Thr88 and Thr92 is essential for Ttrap function.

Although multiple sites on Akt could be SUMOylated, K276 was identified as a major SUMO acceptor site. K276R or E278A mutation reduced SUMOylation of Akt but had little effect on its ubiquitination. Strikingly, these mutations also completely abolished Akt kinase activity. In support of these results, we found that expression of PIAS1 and SUMO1 increased Akt activity, whereas expression of SENP1 reduced Akt1 activity.

The control of Nav density at the cell membrane is crucial to ensuring normal neuronal excitability. Navs are subject to posttranslational modifications that may influence their cell membrane availability. Ubiquitylation is a key process that orchestrates the internalization and subsequent degradation or recycling of Navs. This is accomplished by ubiquitin protein ligases, such as NEDD4-2 (neuronal precursor cell expressed developmentally downregulated-4 type 2).
