Pre- and postsynaptic plasma membranes are always precisely aligned, and are separated by a synaptic cleft of ~20 nm. The cleft contains an undefined proteinaceous material in the middle, and is presumably bridged by synaptic cell-adhesion molecules such as Nrxns and Nlgns that align the pre- and postsynaptic elements and mediate trans-synaptic signaling.|Nlgns bind to both alpha- and beta-Nrxns with nanomolar affinities; binding involves the sixth LNS-domain of alpha-Nrxns which corresponds to the only LNS-domain of beta-Nrxns52. The binding affinities differ characteristically between various pairs of Nlgns and Nrxns, and are controlled by alternative splicing of both Nrxns and Nlgns (Figure 1c)

We show that Glo1 activity is promoted by phosphorylation on Tyrosine 136 via multiple kinases. Glo1 Y136 is phosphorylated by multiple different kinases including all members of the Src family. Depletion of multiple different kinases led to a partial reduction in Glo1(Y136) phosphorylation. These included members of the Src family (Src, Yes1, FGR, and the related Abl1), and of the FAK, EPHA, FGFR, and VEGFR families (Figure 2B), suggesting phosphorylation of Glo1 on Y136 by multiple different kinases. In vitro kinase assays revealed that all the members of the Src family, as well as Epha5 and VEGFR3, can efficiently phosphorylate recombinant Glo1 on Y136 (Figure 2C–D).

Here, we have identified the CCAAT/enhancer binding protein δ (C/EBPδ) as a new substrate for CK2. Using point mutants of C/EBPδ the major phosphorylation site for CK2 was mapped to serine 57, which is located within the transactivation domain of C/EBPδ. For proper functioning as a transcription factor C/EBPδ has to be translocated into the nucleus where it forms heterodimers with other members of the C/EBP family of proteins and ATF4. Here, we found that CK2 phosphorylation does neither influence the subcellular localization of C/EBPδ nor its interaction with C/EBPβ, but rather does CK2 phosphorylation modulate the transcriptional activity of C/EBPδ.

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.

Glycogen synthase kinase-3beta (GSK-3beta) phosphorylates Ser/Thr residues located at the fourth position ahead of the pre-phosphorylated Ser/Thr residues, and inhibitors of GSK-3beta reduce the phosphorylation at Thr182. The results of an in vitro reconstitution assay also indicate that GSK-3beta could be the SIK1 kinase. However, overexpression and knockdown of GSK-3beta in LKB1-defective HeLa cells suggests that GSK-3beta alone may not be able to phosphorylate or activate SIK1, indicating that LKB1 may play a crucial role by phosphorylating SIK1 at Thr182, possibly as an initiator of the autophosphorylation cascade, and GSK-3beta may phosphorylate SIK1 at Thr182 by recognizing the priming-autophosphorylation at Ser186 in cultured cells.

MARCH9, a member of the RING-CH family of transmembrane E3 ubiquitin ligases, down-regulates CD4, major histocompatibility complex-I (MHC), and ICAM-1 in lymphoid cells. To identify novel MARCH9 substrates, we used high throughput flow cytometry and quantitative mass spectrometry by stable isotope labeling by amino acids in cell culture (SILAC) to determine the differential expression of plasma membrane proteins in a MARCH9-expressing B cell line. This combined approach identified 13 potential new MARCH9 targets.

Here we show that LARP4B is a cytoplasmic protein that co-sediments with polysomes and accumulates upon stress induction in stress granules. Biochemical studies further show that the protein interacts with two key factors of the translational machinery, namely, the cytoplasmic poly(A) binding protein (PABPC1) and the receptor for activated C Kinase (RACK1). The biochemical and functional data of LARP4B presented in this study suggest a possible mode of action of LARP4B in translation. Assuming that LARP4B interacts with mRNA-associated PABPC1 and RACK1 simultaneously, it may form a bridge between the 3′ end of mRNAs and the initiating ribosome. This process would lead to mRNA circularization, possibly in an analogous way as it has been described for PABPC1 and eIF4G, the scaffold protein of the cap-binding complex.

PTPRG activation by the P1-WD peptide affected the tyrosine phosphorylation of several signaling molecules. Data analysis identified 31 molecules whose phosphorylation was modified in a statistically significant manner (Table I). inhibition of ABL1, BMX, BTK, DAB1, ITGB1, JAK2, KDR, KIT, LIMK1, MET, PDGFRB, SHC1, and VCL correlates with tyrosine dephosphorylation. In contrast, SRC inhibition correlates with hyperphosphorylation of the inhibitory Tyr530 residue and with dephosphorylation of the activatory Tyr419. Moreover, CDK2 and CTTN inhibition correlates with a hyperphosphorylation of the inhibitory Tyr15 and Tyr470, respectively. In contrast, a subgroup of 13 proteins, including BLNK, DOK2, ERBB2, GRIN2B, INSR, PDGFRA, PRKCD, PXN, STAT1, STAT2, STAT3, STAT5A, and ZAP70, appears to be activated by PTPRG activity.
