We showed in mammalian cells that liver kinase B1 (LKB1) activated the microtubule affinity-regulating kinase 3 (MARK3), which in turn phosphorylated ARHGEF2 at Ser151 This modification disrupted the interaction between ARHGEF2 and DYNLT1 by generating a 14-3-3 binding site in ARHGEF2, thus causing ARHGEF2 to dissociate from microtubules.

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)

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.

We found that SATB2 differs from the closely related thymocyte-specific protein SATB1 by modifications of two lysines with the small ubiquitive related modifier (SUMO), which are augmented specifically by the SUMO E3 ligase PIAS1.

PTPN18 knockdown selectively enhances the EGF-induced tyrosine phosphorylation of the HER2 Y1112, Y1196 and Y1248 sites. |Whereas the catalytic domain of PTPN18 blocks lysosomal routing and delays the degradation of HER2 by dephosphorylation of HER2 on pY(1112), the PEST domain of PTPN18 promotes K48-linked HER2 ubiquitination and its rapid destruction via the proteasome pathway and an HER2 negative feedback loop.
