Tec family protein tyrosine kinases (tfks) play a central role in hematopoietic cellular signaling. Initial activation takes place through specific tyrosine phosphorylation situated in the activation loop. Further activation occurs within the sh3 domain via a transphosphorylation mechanism. Here, we could confirm that y223 is the only site in the btk-sh3 domain being detectably phosphorylated

The activation loops of the MLK family are highly homologous, and so one might predict that the same residues would be key to their activation. Functional data presented here, however, demonstrate that the key residue for activation of MLK1, Thr312, differs from the key residue for activation of MLK3.

ARTS binding to XIAP is specific and related to its pro-apoptotic function, as mutant forms of ARTS (or related septins) that fail to bind XIAP failed to induce apoptosis. ARTS leads to decreased XIAP protein levels and caspase activation. Our data suggest that ARTS induces apoptosis by antagonizing IAPs.

Here, we show that TRIM5alpha functions as a RING-finger-type E3 ubiquitin ligase both in vitro and in vivo and ubiquitinates itself in cooperation with the E2 ubiquitin-conjugating enzyme UbcH5B. Thus, the ubiquitination of TRIM5alpha is catalyzed by itself and Ro52. Unexpectedly, although TRIM5alpha is ubiquitinated, our results have revealed that the proteasome inhibitors MG115 and MG132 do not stabilize it in HeLa cells, suggesting that the ubiquitination of TRIM5alpha does not lead to proteasomal degradation. Importantly, TRIM5alpha is clearly conjugated by a single ubiquitin molecule (monoubiquitination). Our monoubiquitin-fusion assay suggests that monoubiquitination is a signal for TRIM5alpha to translocate from cytoplasmic bodies to the cytoplasm.

In this study, we identified USP7 (also known as HAUSP), which is a member of a family of proteins that cleave polyubiquitin chains and/or ubiquitin precursors, as an interacting protein with Chfr by immunoaffinity purification and mass spectrometry, and their interaction greatly increases the stability of Chfr. In fact, USP7 can remove ubiquitin moiety from the autoubiquitinated Chfr both in vivo and in vitro, which results in the accumulation of Chfr in the cell. USP7 mediates deubiquitination of Chfr.

CRE-BPa specifically binds to CRE as a homodimer or heterodimer with c-Jun or CRE-BP1. In CAT cotransfection experiments using CV-1 cells, transient expression of each of four CRE-BPa proteins caused a 1.6- to 3.4-fold increase of CRE-dependent transcription

After this priming step, Gwl can intramolecularly phosphorylate its C-terminal tail at pS883; this site probably plays a role similar to that of the tail/Z motif of other AGC kinases.

We show that phosphorylation of s621 turns over rapidly and is enriched in the activated pool of endogenous raf-1. The phosphorylation on this site can be mediated by raf-1 itself but also by other kinase(s)

They also demonstrate that replacement of the major site of autophosphorylation of p56lck (tyrosine 394) by a phenylalanine residue abolishes the ability to activate p56lck by CD4 cross-linking, implying that this residue is critical for the positive regulation of the Lck tyrosine kinase activity by CD4.

EGFR is positively correlated with PELI1 expression in breast cancers, and its activation led to the phosphorylation of PELI1 at Tyr154 and Thr264, which subsequently activated its E3 ubiquitin ligase. Simultaneously, PELI1 physically interacted with and enhanced the stability of EGFR via the K63-linked polyubiquitination in reverse.

The RING finger motifs of DIP-1 have E3 ligase activity that can auto-ubiquitinate DIP-1 in vitro. In vivo, DIP-1 is detected as a polyubiquitinated protein, suggesting that the intracellular levels of DIP-1 are regulated by the ubiquitin-proteasome system.
