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.

Gp78 specifically recruits MmUBC7, a ubiquitin-conjugating enzyme (E2) implicated in ER-associated degradation (ERAD), through a region distinct from the RING finger. gp78 can target itself for proteasomal degradation in a RING finger- and MmUBC7-dependent manner. Importantly, gp78 can also mediate degradation of CD3-delta, a well-characterized ERAD substrate.

The two members of the ZEB family of zinc finger factors (ZEB-1/deltaEF1 and ZEB-2/SIP1) regulate TGFbeta/BMP signaling in opposite ways: ZEB-1/deltaEF1 synergizes with Smad-mediated transcriptional activation, while ZEB-2/SIP1 represses it. Here we report that these antagonistic effects by the ZEB proteins arise from the differential recruitment of transcriptional coactivators (p300 and P/CAF) and corepressors (CtBP) to the Smads. Thus, while ZEB-1/deltaEF1 binds to p300 and promotes the formation of a p300-Smad transcriptional complex, ZEB-2/SIP1 acts as a repressor by recruiting CtBP.

Aberrant expression of CRYAB has been shown to be associated with several neurological diseases and malignant neoplasms. To identify transcriptional regulators of CRYAB expression, we examined its promoter for binding sites of transcription factors and identified four potential AP-2 binding sites in addition to a p53 binding site reported previously|Taken together, our results indicate that AP-2_ up-regulates the transcription of the CRYAB gene through stabilizing p53

Here we report the cloning of a novel cDNA, termed Solt, from a mouse testis cDNA library. Its gene product, Solt, interacts with the leucine zipper region of SoxLZ/Sox6. In transient transfection assays with SoxLZ/Sox6 containing the transactivation domain of herpes simplex virus VP16, the expression of a luciferase reporter gene under the control of a promoter containing a synthetic cis element that is bound by the HMG box of SoxLZ/Sox6 was poorly enhanced in the presence of Solt.

The phosphorylation of Bcl-2 resulted in a reduction in anti-apoptotic function, implying that dephosphorylation promoted the anti-apoptotic activity of Bcl-2 protein in human tumor cell lines. Thus, the present findings suggest that ERK and PP2A are physiological regulators of Bcl-2 phosphorylation, and these enzymes exert an influence on the anti-apoptotic function of Bcl-2.phosphorylation of Bcl2 at Ser70 is proposed to be a dynamic process regulated by the sequential action of an agonist-activated Bcl2 kinase and PP2A.

Binding of the phosphotyrosinebinding (PTB)-domain-like subdomain of the protein 4.1, ezrin, radixin, moesin (FERM) domain of talin to the conserved WxxxNP(I/L)Y motif of the β-integrin tail permits additional weaker interactions between talin and the membrane-proximal region of the tail that trigger integrin activation, probably through the disruption of inhibitory interactions between α- and β-subunit cytoplasmic tails.
