ARC Expands the DAAM1 Microexon‐Mediated Actin–RHOA/ROCK Interplay
Cytoskeleton, EarlyView.ABSTRACT Actin cytoskeleton and its dynamics play a crucial role in synaptic function, influencing dendritic spines' structural and functional plasticity. Recent findings unveiled the significance of alternative splicing of a neural‐specific microexon in DAAM1 in modulating actin's role in synaptic processes.

The casein kinases Yck1p and Yck2p act in the secretory pathway, in part, by regulating the Rab exchange factor Sec2p. [PDF]
, 2016 Sec2p is a guanine nucleotide exchange factor that activates Sec4p, the final Rab GTPase of the yeast secretory pathway. Sec2p is recruited to secretory vesicles by the upstream Rab Ypt32p acting in concert with phosphatidylinositol-4-phosphate (PI(4)P).

Identification of novel genes regulating the development of the palate
Developmental Dynamics, EarlyView.Abstract Background The International Mouse Phenotyping Consortium (IMPC) has generated thousands of knockout mouse lines, many of which exhibit embryonic or perinatal lethality. Using micro‐computed tomography (micro‐CT), the IMPC has created and publicly released three‐dimensional image data sets of embryos from these lethal and subviable lines.

Tiam1/Rac1 complex controls Il17a transcription and autoimmunity
Nature Communications, 2016 Tiam1 is a guanine nucleotide exchange factor for the Rho-family GTPase Rac1. Here, the authors show that nuclear Tiam1 and Rac1 bind to RORγt on the IL-17 promoter, activating its transcription, and that inhibiting Tiam1/Rac1 is beneficial in a mouse ...

Dynamic cycling of eIF2 through a large eIF2B-containing cytoplasmic body: implications for translation control [PDF]
, 2005 The eukaryotic translation initiation factor 2B (eIF2B) provides a fundamental controlled point in the pathway of protein synthesis. eIF2B is the heteropentameric guanine nucleotide exchange factor that converts eIF2, from an inactive guanosine ...

The Emerging Role of Guanine Exchange Factors in ALS and other neurodegenerative diseases
Frontiers in Cellular Neuroscience, 2014 Small GTPases participate in a broad range of cellular processes such as proliferation, differentiation and migration. The exchange of GDP for GTP resulting in the activation of these GTPases is catalyzed by a group of enzymes called guanine nucleotide ...

The Human SLC25A33 and SLC25A36 Genes of Solute Carrier Family 25 Encode Two Mitochondrial Pyrimidine Nucleotide Transporters [PDF]
, 2014 The human genome encodes 53 members of the solute carrier family 25 (SLC25), also called the mitochondrial carrier family, many of which have been shown to transport inorganic anions, amino acids, carboxylates, nucleotides, and coenzymes across the inner
