STIM1, PKC-δ and RasGRP set a threshold for proapoptotic Erk signaling during B cell development. [PDF]
, 2011 Clonal deletion of autoreactive B cells is crucial for the prevention of autoimmunity, but the signaling mechanisms that regulate this checkpoint remain undefined. Here we characterize a previously unrecognized Ca(2+)-driven pathway for activation of the

The RasGrf family of mammalian guanine nucleotide exchange factors
Biochimica et Biophysica Acta (BBA) - Reviews on Cancer, 2011 RasGrf1 and RasGrf2 are highly homologous mammalian guanine nucleotide exchange factors which are able to activate specific Ras or Rho GTPases. The RasGrf genes are preferentially expressed in the central nervous system, although specific expression of either locus may also occur elsewhere.

Decoding the Role of Caveolin‐1 in Morphological Diversity and Self‐Renewal of Breast Cancer Cells
Cell Proliferation, EarlyView.The silence of caveolin‐1 (Cav‐1) reproduced the morphological evolutionary behaviour of cancer cells, which is similar to the epithelial‐mesenchymal transition process. And Cav‐1 dependent morphological changes could affect cancer cell self‐renewal capacity through maintaining the morphological stability.

Human FASTK preferentially binds single‐stranded and G‐rich RNA
The FEBS Journal, EarlyView.Although FASTK is known to play a role in mRNA biology, the mechanism through which it recognizes RNA has yet to be unraveled. Here, we used purified human FASTK to characterize its RNA‐binding properties in vitro. We found that FASTK prefers ssRNA oligonucleotides containing guanines with the potential to form G‐quadruplexes and binds robustly to any ...

Targeting dermatophyte Cdc42 and Rac GTPase signaling to hinder hyphal elongation and virulence
iScienceSummary: The development of antifungal drugs requires novel molecular targets due to limited treatment options and drug resistance. Through chemical screening and establishment of a novel genetic technique to repress gene expression in Trichophyton ...

Gz, a guanine nucleotide-binding protein with unique biochemical properties [PDF]
, 1990 Cloning of a complementary DNA (cDNA) for Gz alpha, a newly appreciated member of the family of guanine nucleotide-binding regulatory proteins (G proteins), has allowed preparation of specific antisera to identify the protein in tissues and to assay it ...

EHD4 and ASAP2 are critical negative regulators of the claudin‐5‐based endothelial barrier
The FEBS Journal, EarlyView.Cell‐surface CLDN‐5 protein levels can be evaluated using a probe that can bind to the extracellular domains of CLDN‐5. A probe derived from Clostridium perfringens enterotoxin allows us to isolate cells with high CLDN‐5 protein levels from a knockout cell library.

Plant Biotechnology Journal, EarlyView.ABSTRACT Abiotic stresses severely constrain soybean productivity worldwide. Here we demonstrate that gmeif2b5 (eukaryotic initiation factors) mutants confer dual stress tolerance through coordinated mechanisms. Integrative RNA‐Seq and protein interaction analyses revealed that gmeif2b5 mutants increase lignin deposition to increase drought resilience ...
