Phosphatidylserine decarboxylase 1 autocatalysis and function does not require a mitochondrial-specific factor.
Claypool et al., Baltimore, United States. In J Biol Chem, Jun 2015
The mitochondrial enzyme that generates PE is phosphatidylserine decarboxylase 1 (Psd1p).
Arf6 guanine nucleotide exchange factor cytohesin-2 binds to CCDC120 and is transported along neurites to mediate neurite growth.
Yamauchi et al., Tokyo, Japan. In J Biol Chem, 2015
Cytohesin-2 is a guanine nucleotide exchange factor for Arf6, an Arf family molecular switch protein, controlling cell morphological changes such as neuritogenesis.
Activation of the Small G Protein Arf6 by Dynamin2 through Guanine Nucleotide Exchange Factors in Endocytosis.
Kanaho et al., Tsukuba, Japan. In Sci Rep, 2014
Of the Arf6-specific guanine nucleotide exchange factors, EFA6A, EFA6B, and EFA6D specifically interact with Dyn2.
A Yeast Mutant Deleted of GPH1 Bears Defects in Lipid Metabolism.
Daum et al., Graz, Austria. In Plos One, 2014
In a previous study we demonstrated up-regulation of the yeast GPH1 gene under conditions of phosphatidylethanolamine (PE) depletion caused by deletion of the mitochondrial (M) phosphatidylserine decarboxylase 1 (PSD1) (Gsell et al., 2013, PLoS One.
Exchange factor EFA6R requires C-terminal targeting to the plasma membrane to promote cytoskeletal rearrangement through the activation of ADP-ribosylation factor 6 (ARF6).
Kanamarlapudi, Swansea, United Kingdom. In J Biol Chem, 2014
The exchange factor for ARF6 (EFA6) R has been identified as a biomarker for ovarian cancer.
The RLIP76 N-terminus binds ARNO to regulate PI 3-kinase, Arf6 and Rac signaling, cell spreading and migration.
Goldfinger et al., Philadelphia, United States. In Biochem Biophys Res Commun, 2014
RLIP76 harbors docking sites for many proteins, and we have found that it interacts with ARNO, a guanine nucleotide exchange factor for Arf6, and that RLIP76 regulates activation of Rac1 via Arf6, and regulates cell spreading and migration in an ARNO and Arf6-dependent manner.
Aberrant methylation of PSD disturbs Rac1-mediated immune responses governing neutrophil chemotaxis and apoptosis in ulcerative colitis-associated carcinogenesis.
Konishi et al., Saitama, Japan. In Int J Oncol, 2012
Aberrant methylation of PSD occurs in UC-associated colorectal mucosa, enabling circumvention of Rac1 immune responses governing neutrophil chemotaxis and apoptosis, and plays a pivotal role in the mechanisms underlying UC-associated carcinogenesis.
Aberrant methylation of the Pleckstrin and Sec7 domain-containing gene is implicated in ulcerative colitis-associated carcinogenesis through its inhibitory effect on apoptosis.
Konishi et al., Saitama, Japan. In Int J Oncol, 2012
Both levels of accumulation of F-actin and apoptosis were significantly decreased in specimens from UC patients with PSD methylation compared to those without PSD methylation.
From cradle to twilight: the carboxyl terminus directs the fate of the A(2A)-adenosine receptor.

Daskalova et al., Sofia, Bulgaria. In J Integr Neurosci, 2011
Four degrees of systematic paranodal demyelinations (two mild demyelinations termed PSD1 and PSD2, without/with aqueous layers respectively, and two severe demyelinations termed PSD3 and PSD4, with/without aqueous layers, respectively) are simulated using our previous multi-layered model of human motor nerve fibre.
