To determine whether mitotic CDK phosphorylates ATAD5, a CDK1 inhibitor (RO3306) was applied to nocodazole-arrested cells (Figure S3F). CDK1 inhibition resulted in a loss of S653 phosphorylation (Figure S3F). These data meant that the S653 residue in the BET BD of ATAD5 is phosphorylated by mitotic CDK. This result suggested that the BRD4-ATAD5 interaction is inhibited during mitosis.

In vitro kinase assay revealed that shcc is a potent substrate of the activated alk kinase. The alk gene locus was significantly amplified in both of these cell lines, suggesting that gene amplification leads to constitutive activation of the alk kinase, which results in hyperphosphorylation of shcc.

Our data indicate that Nedd4-2 binds to two family members, TTYH2 and TTYH3, which contain consensus PY ((L/P)PXY) binding sites for HECT type E3 ubiquitin ligases, but not to TTYH1, which lacks this motif. Consistently, Nedd4-2 ubiquitinates both TTYH2 and TTYH3. Importantly, we have shown that endogenous TTYH2 and Nedd4-2 are binding partners and demonstrated that the TTYH2 PY motif is essential for these interactions. We have also shown that Nedd4-2-mediated ubiquitination of TTYH2 is a critical regulator of cell surface and total cellular levels of this protein.

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.

Mechanistically, RNF146 directly interacts with poly(ADP-ribose) through its WWE domain, and promotes degradation of PARsylated proteins. Using proteomics approaches, we have identified BLZF1 and CASC3 as further substrates targeted by tankyrase and RNF146 for degradation.

SHANK proteins are ‘master’ scaffolding proteins that tether and organize intermediate scaffolding proteins. They are located at excitatory synapses, where they are crucial for proper synaptic development and function. SAPAP proteins subsequently bind to the PDZ domain of members of the SHANK protein family. SHANK proteins then bind to the actin cytoskeleton and to Homer protein, which in turn interacts with mGluRs. Through these extended links, PSD95, SAPAP, SHANK and Homer proteins form a quaternary complex that brings together mGluR and NMDAR complexes in the PSD (FIG. 3).

Site-specific mutagenesis of maz revealed that the serine residue at position 480 was the major site of phosphorylation by ckii both in vitro and in vivo. Phosphorylation of maz by ckii at this serine residue was required for maximum binding of maz to the pyrimidine-rich dna of the nuclease-hypersensitive element (nhe) in the 5'-end promoter region of the c-myc gene. Mutation of serine at position 480 to alanine eliminated the dna-binding activity of maz to this element.

We have cloned and characterized a new member of the PHD zinc finger family called Pf1 that interacts with two global transcription corepressors: mSin3A and TLE. Pf1 interacts with TLE. The Groucho/TLE proteins are members of an abundant corepressor family, and we hypothesized that Pf1 might interact with TLE family members. Together, these data suggest that in the absence of interactions with mSin3A, Gal4-Pf1 (102–273 L212P/A216P)-dependent repression can be attributed to interaction with endogenous TLE.

We show that COH1 forms a physical and functional complex with RAB6. Our results point to a role of COH1 as a RAB6 effector protein. Depletion of COH1 leads to decreased neurite outgrowth in cultured primary hippocampal neurons. These results establish a critical role for RAB6-dependent function of COH1 in neuritogenesis by regulating Golgi complex organization.
