The observation that GRK2 co-immunoprecipitates with Epac1 suggests a direct association between GRK2 and Epac1 in DRGs. xref A detailed study of the influence of GRK2 on the Epac1 level found that phosphorylation of ser108 in Epac1 by GRK2 can lead to a reduction of Epac1 activation. xref Downstream consequence of a reduction of GRK2 was explored. xref Low GRK2 expression in GRK2(\u00b1) DRGs was found to facilitate CPT-induced Rap1 activation and increase the phosphorylated ERK1/2 level.

ZNF804A has been implicated in susceptibility to schizophrenia by several genome-wide association studies (GWAS), follow-up association studies and meta-analyses. ZNF804A was identified as a schizophrenia-associated gene by GWAS and was predicted to play a role in DNA binding and transcription To identify the genes that are affected by ZNF804A, we manipulated the expression of the ZNF804A protein in HEK293 human embryonic kidney cell lines and performed a cDNA microarray analysis followed by qPCR. We found that ZNF804A-overexpression up-regulated four genes (ANKRD1, INHBE, PIK3AP1, and DDIT3) and down-regulated three genes (CLIC2, MGAM, and BIRC3).

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.

This work demonstrates that tif1beta is phosphorylated on ser473, the alteration of which is dynamically associated with cell cycle progression and functionally linked to transcriptional regulation. Phosphorylation of tif1beta/ser473 is mediated by the pkcdelta pathway and is closely linked to cell proliferation. Phosphorylation of tif1beta/ser473 coincides with the induction of cell cycle gene cyclin a2 at the s-phase. Promoter of cyclin a2 gene is occupied by tif1beta and such occupancy is inversely correlated with ser473 phosphorylation. Non-phosphorylated tif1beta/ser473 allowed greater tif1beta association with the regulatory regions and the consequent repression of these genes.

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).

The F-box DNA helicase 1 (FBH1) is a 3'-5' DNA helicase with a putative function as a negative regulator of HR. It is the only known DNA helicase to contain an F-box, suggesting that one of its functions is to act as a ubiquitin ligase as part of an SCF (SKP1, CUL1 and F-box) complex. Here we report that the central player in HR, RAD51, is ubiquitylated by the SCF(FBH1) complex. Expression of an ubiquitylation-resistant form of RAD51 in human cells leads to hyperrecombination, as well as several phenotypes indicative of an altered response to DNA replication stress. However, K58/64R RAD51 was ubiquitylated much less efficiently by FBH1 in vitro than was wild-type (WT) RAD51 (Fig. 1d), confirming that the primary sites of modification by FBH1 on RAD51 are K58 and K64.
