Smad2/3 interacts with c-ski through its c-terminal mh2 domain in a tgf-beta-dependent mannerc-ski is incorporated in the smad dna binding complex, interferes with the interaction of smad3 with a transcriptional co-activator, p300, and in turn recruits hdac. c-ski is thus a transcriptional co-repressor that links smads to hdac in tgf-beta signaling.

Synthesis of mature histone mRNA requires only a single processing reaction: an endonucleolytic cleavage between a conserved stem-loop and a purine-rich downstream element to form the 3' end. The stem-loop binding protein (SLBP) is required for processing, and following processing, histone mRNA is transported to the cytoplasm, where SLBP participates in translation of the histone mRNA|We used radiolabeled probes generated by PCR targeting the open reading frame (ORF) to detect histones H2A, H2B, H3, H4, and H1 and used 7SK snRNA as a loading control (Fig. 2A). The abundance of histone H2A, H2B, H3, and H4 mRNAs is reduced to 37% to 70% of control levels in the SLBP knockdown cells when compared to the C2 control.

Site‐directed mutagenesis of the SGK1 phosphorylation sites in the Nedd4‐2 protein (S382A,S468ANedd4‐2) and in the EAAT1 protein (T482AEAAT1, T482DEAAT1) significantly blunts the effect of S422DSGK1. Introduction of a negative charge at the SGK phosphorylation site in the EAAT1 protein leads to a strong stimulation of the carrier, whereas replacement with alanine markedly decreases the EAAT1‐mediated current. These observations suggest that SGK1 exerts its effect not only by phosphorylation of Nedd4‐2 but also by phosphorylation of EAAT1.

Unlike most other known examples of homeoprotein interactions, association of Msx and Dlx proteins does not promote cooperative DNA binding; instead, dimerization and DNA binding are mutually exclusive activities. Msx proteins act as transcriptional repressors and Dlx proteins act as activators, while in combination, Msx and Dlx proteins counteract each other's transcriptional activities.

Mutations in the Autism susceptibility candidate 2 gene (AUTS2), whose protein is believed to act in neuronal cell nuclei, have been associated with multiple psychiatric illnesses, including autism spectrum disorders, intellectual disability, and schizophrenia. Here we show that cytoplasmic AUTS2 is involved in the regulation of the cytoskeleton and neural development. AUTS2 activates Rac1 to induce lamellipodia but downregulates Cdc42 to suppress filopodia. Our loss-of-function and rescue experiments show that a cytoplasmic AUTS2-Rac1 pathway is involved in cortical neuronal migration and neuritogenesis in the developing brain. These results suggest that FL-AUTS2 can activate Rac1 via interaction with P-Rex1 and the Elmo2/Dock180 complex to regulate actin dynamics in N1E-115 cells.

Here we show that Akt, Erk2, and IKK1/2 phosphorylate Bcl3. Phosphorylation of Ser33 by Akt induces switching of K48 ubiquitination to K63 ubiquitination and thus promotes nuclear localization and stabilization of Bcl3. Phosphorylation by Erk2 and IKK1/2 of Ser114 and Ser446 converts Bcl3 into a transcriptional coregulator by facilitating its recruitment to DNA.

One of the hallmarks of EMT is loss of E-cadherin and gain of N-cadherin expression, which are regulated by the core EMT-inducing transcription factors (EMT-TFs), such as Zeb1/2, Snai1/2 and Twist1. Here, we find that EMT-TFs can be dynamically degraded by an atypical ubiquitin E3 ligase complex Skp1-Pam-Fbxo45 (SPFFbxo45) through the ubiquitin proteasome system (UPS). The key step is recognition of EMT-TFs by Fbxo45 through its SPRY domain for Zeb2, or F-box domain for the other three EMT-TFs Snai1, Snai2 and Twist1, respectively.

Here, we identify that the mitochondrially localized PGAM5 phosphatase interacts with and dephosphorylates FUNDC1 at serine 13 (Ser-13) upon hypoxia or carbonylcyanide p-trifluoromethoxyphenylhydrazone (FCCP) treatment. Dephosphorylation of FUNDC1 catalyzed by PGAM5 enhances its interaction with LC3, which is abrogated following knockdown of PGAM5 or the introduction of a cell-permeable unphosphorylated peptide encompassing the Ser-13 and LIR of FUNDC1. We further observed that CK2 phosphorylates FUNDC1 to reverse the effect of PGAM5 in mitophagy activation.

In conclusion, we propose that RIM2α and RIM3γ directly interact with the C-terminus of the pore-forming subunit of CaV1.3 Ca2+ channels and positively regulate their plasma membrane expression in HEK293 cells.

Phosphorylated DUE-B forms homodimers, whereas de-phosphorylated DUE-B interacts with the Mcm2–7 complex and aminoacyl-tRNA synthetases. We find that CKII can prime DUE-B for Cdc7 phosphorylation. Confirming the importance of DUE-B phosphorylation in replication initiation, a C-terminal Ser/Thr to Ala mutant blocks Cdc45 and RPA loading on sperm chromatin and inhibits DNA replication. DUE-B C-terminal phosphorylation sites (serine 179, 181, 182, 194, 196, 197, 204, 205, and threonine 187) were mutated to unphosphorylatable alanine (DUE-B(S/T)-A) or phosphomimic aspartic acid (DUE-B(S/T)-D).

FNIP1 and FNIP2 facilitate FLCN binding to Hsp90 chaperone. Our results suggest that FNIP1 is a potent inhibitor of Hsp90 ATPase activity, as 200 nM of FNIP1 inhibits Hsp90 ATPase activity by 50-fold. FNIP2 also has shown inhibitory activity towards Hsp90; however, it required 1.6 μM of FNIP2 to inhibit the ATPase activity by eightfold. Although we use the term ‘inhibition' here, FNIPs seem only to be slowing the chaperone cycle.
