Synaptophysin I interacts with VAMP2 and controls its subcellular distribution. On the SV membrane, VAMP2 is engaged in a complex with synaptophysin I, which is mutually exclusive with the formation of fusogenic SNARE complexes. This model implicates synaptophysin I in escorting VAMP2 to the sites where exocytosis must take place exclusively after the arrival of the appropriate stimulus. We show that, at early stages along the secretory pathway, synaptophysin I directs sorting of VAMP2 to vesicles exhibiting limited availability for constitutive exocytosis.

Previous studies have established that YY1 interacts with histone acetyltransferases p300 and CREB-binding protein (CBP) and histone deacetylase 1 (HDAC1), HDAC2, and HDAC3. Here, we present evidence that the activity of YY1 is regulated through acetylation by p300 and PCAF and through deacetylation by HDACs. YY1 was acetylated in two regions: both p300 and PCAF acetylated the central glycine-lysine-rich domain of residues 170 to 200, and PCAF also acetylated YY1 at the C-terminal DNA-binding zinc finger domain. Acetylation of the central region was required for the full transcriptional repressor activity of YY1 and targeted YY1 for active deacetylation by HDACs.

The influence of DPP3 on the Keap1-Nrf2/ARE signal pathway suggest a direct involvement of DPP3 in the oxidative stress response [8,14,31,53,99,100]. It was shown that DPP3 competes with Nrf2 through the ETGE motif to bind to Keap1 and consequently enhances the translocation of Nrf2 to the nucleus, thereby driving the expression of an array of genes encoding antioxidative enzymes [99]. More specifically, binding of DPP3 to Keap1 releases Nrf2, and thus, prevents its degradation through the 26S proteasome

Depletion of CEP135 not only perturbed the centriolar localization of CPAP, but also blocked CPAP-induced centriole elongation. We propose that CEP135 may serve as a linker protein that directly connects the central hub protein, hSAS-6, to the outer MTs, and suggest that this interaction stabilizes the proper cartwheel structure for further CPAP-mediated centriole elongation.

Here, we show that ULK1 is upregulated and translocates to fragmented mitochondria upon mitophagy induction by either hypoxia or mitochondrial uncouplers. At mitochondria, ULK1 interacts with FUNDC1, phosphorylating it at serine 17, which enhances FUNDC1 binding to LC3.

Bonni and coworkers demonstrated that mst1 can phosphorylate foxo3 (and subsequently, foxo1) principally ser207 (ser212 in foxo1), a conserved site in the forkhead domain. This phosphorylation interdicts 14-3-3 binding, promotes foxo nuclear residence and transcriptional activity. The other major signaling modules that directly regulate the activity of the foxo factors include the stress-activated jun-n-terminal kinase (jnk), the mammalian ortholog of the ste20-like protein kinase (mst1), and the deacetylase sirt1.

IL1 receptor accessory protein like, a protein involved in X-linked mental retardation, interacts with Neuronal Calcium Sensor-1 and regulates exocytosis. our data show that IL1RAPL interacts only with NCS-1 through its specific C-terminal domain. The functional relevance of IL1RAPL activity was further supported by the inhibitory effect on exocytosis in PC12 cells overexpressing IL1RAPL. Taken together, our data suggest that IL1RAPL may regulate calcium-dependent exocytosis and provide insight into the understanding of physiopathological mechanisms underlying cognitive impairment resulting from IL1RAPL dysfunction.

We show that SK-UT-1B cells express a novel splice variant of Skp2 that localizes to the cytoplasm and that cyclin D1 ubiquitination takes place in the nucleus. We propose that the translocation of Skp2 into the nucleus is required for the ubiquitination of cyclin D1 and that the absence of the SCF(Skp2) complex in the nucleus of SK-UT-1B cells is the mechanism underlying the ubiquitination defect observed in this cell line.
