The GPCRs are allocated in five families where the GLP-1R and GIPR are found within the secretin family, also classified as class B [31,32]. Upon stimulation by an extracellular stimuli (ligand), GPCRs undergo conformational changes, and triggers downstream intracellular signals by coupling with G proteins (or other intracellular proteins such as arrestins), causing a wide range of both physiological and pathological processes.To stimulate insulin secretion, and in the presence of elevated blood glucose concentrations, GLP-1R activation in pancreatic beta cells promote recruitment and activation of Gαs protein leading to adenylate cyclase-mediated cAMP production, elevation of Ca2+, and ERK1/2 phosphorylation (Fig. 3)

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.

TRC8/RNF139 encodes an endoplasmic reticulum-resident E3 ubiquitin ligase that inhibits growth in a RING- and ubiquitylation-dependent manner. TRC8 also contains a predicted sterol-sensing domain. Here, we report that TRC8 protein levels are sterol responsive and that it binds and stimulates ubiquitylation of the endoplasmic reticulum anchor protein INSIG. Thus, we conclude that INSIG-1 and 2 physically interact with TRC8, and that TRC8 enhances ubiquitylation of INSIG-1 in a RING-dependent manner

Acyl-protein thioesterase 2 catalyzes the deacylation of peripheral membrane-associated GAP-43. In this work, we investigated the deacylation of growth-associated protein-43 (GAP-43), a dually acylated protein at cysteine residues 3 and 4. Thus, the results demonstrate that APT-2 is the protein thioesterase involved in the acylation/deacylation cycle operating in GAP-43 subcellular distribution.we demonstrated that the reduction in the protein level was abrogated when cells were also treated with proteasome inhibitors (chloroquine, MG132 and lactacystin) which strongly suggest that GAP-43 deacylation is an early and necessary step for its later ubiquitination and degradation by the proteasome. In addition, it also suggests that acyl-protein thioesterase levels not only regulate palmitate turnover but also global protein turnover of GAP-43.

Human CapZIP was phosphorylated at Ser-179 and Ser-244 by MAPKAP-K2 (mitogen-activated protein kinase-activated protein kinase 2) or MAPKAP-K3 in vitro. In the present paper we have identified CapZIP as a protein that is phosphorylated exceptionally rapidly by several SAPKs in vitro (Figure 4), and which is expressed in muscles and immune cells. Both MAPKAP-K2 and MAPKAP-K3 phosphorylated CapZIP at Ser-179 in vitro. An important clue to the function of CapZIP and its phosphorylation came from the finding that it binds to the actin-capping protein CapZ (Figure 7A), and that cellular stresses trigger the dissociation of these two proteins (Figure 7B).Such an effect is presumably lost when CapZIP is phosphorylated and dissociates from CapZ.

We found that KLHL2, as well as KLHL3, was co-immunoprecipitated with all four WNK isoforms. The direct interaction of KLHL2 with WNKs was confirmed on fluorescence correlation spectroscopy. Co-expression of KLHL2 and Cullin3 decreased the abundance of WNK1, WNK3 and WNK4 within HEK293T cells, and a significant increase of WNK4 ubiquitination by KLHL2 and Cullin3 was observed both in HEK293T cells and in an in vitro ubiquitination assay. These results suggest that KLHL2-Cullin3 also functions as an E3-ligase for WNK isoforms within the body.

MKRN1 functions as an E3 ubiquitin-ligase for hTERT in vitro and in vivo. Furthermore, we have used the yeast two-hybrid method to identify a novel RING finger gene (MKRN1) encoding an E3 ligase that mediates ubiquitination of hTERT. Overexpression of MKRN1 in telomerase-positive cells promotes the degradation of hTERT and decreases telomerase activity and subsequently telomere length.
