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.

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.

We have found that T cell p38 MAP kinase (MAPK), which is directly phosphorylated and activated by ZAP-70 downstream of the TCR, in turn phosphorylates Thr-293 in the interdomain B region of ZAP-70. These results identify a tight negative feedback loop in which ZAP-70-activated p38 reciprocally phosphorylates ZAP-70 and destabilizes the signaling complex.

GSK3\u03b2 is an important serine/threonine kinase to regulate PPAR\u03b3 coactivator-1\u03b1 degradation. , GSK3\u03b2 reduces PPAR\u03b3 coactivator-1\u03b1 levels by phosphorylating PPAR\u03b3 coactivator-1\u03b1 and subsequently stimulating PPAR\u03b3 coactivator-1\u03b1 degradation by the ubiquitin-proteasomal system.|Within them, GSK3beta, which can phosphorylate PGC-1alpha and promote its ubiquitin mediated degradation , , was upregulated significantly in mnd2 mouse brain and spinal cord compared with that in wide-type mice (XREF_FIG).

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.

We report that MRAP and MRAP2 can interact with all 5 MCRs. This interaction results in MC2R surface expression and signaling. In contrast, MRAP and MRAP2 can reduce MC1R, MC3R, MC4R, and MC5R responsiveness to [Nle4,D-Phe7]alpha-melanocyte-stimulating hormone (NDP-MSH). MRAP and MRAP2 can reduce the surface expression of MC4R and also the signaling of this receptor. we observed a significant decrease in the cell-surface expression of MC4R and MC5R in the presence of MRAP and MRAP2. It is interesting that MRAP and MRAP2 have opposite effects in the modulation of different MCR family members.
