RAS guanyl releasing protein 2

The protein encoded by this gene is a brain-enriched nucleotide exchanged factor that contains an N-terminal GEF domain, 2 tandem repeats of EF-hand calcium-binding motifs, and a C-terminal diacylglycerol/phorbol ester-binding domain. This protein can activate small GTPases, including RAS and RAP1/RAS3. The nucleotide exchange activity of this protein can be stimulated by calcium and diacylglycerol. Three alternatively spliced transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Jul 2008] (from NCBI)
Papers on CalDAG-GEFI
Relative contributions of stromal interaction molecule 1 and CalDAG-GEFI to calcium-dependent platelet activation and thrombosis.
Bergmeier et al., Philadelphia, United States. In J Thromb Haemost, 2011
(i) STIM1/SOCE is critical for procoagulant activity but not the proadhesive function of platelets; and (ii) at the site of vascular injury, STIM1 and CalDAG-GEFI are critical for the first wave of thrombin generation mediated by procoagulant platelets
CalDAG-GEFI deficiency protects mice in a novel model of Fcγ RIIA-mediated thrombosis and thrombocytopenia.
Bergmeier et al., Philadelphia, United States. In Blood, 2011
we evaluated the contribution of CalDAG-GEFI to platelet activation in a model of immune-mediated thrombocytopenia and thrombosis syndromes
The kinetics of αIIbβ3 activation determines the size and stability of thrombi in mice: implications for antiplatelet therapy.
Bergmeier et al., Philadelphia, United States. In Blood, 2011
Studies indicate that CalDAG-GEFI mediates the rapid but reversible activation of integrin alphaIIbbeta3, and the adenosine diphosphate receptor P2Y12 facilitates delayed but sustained integrin activation.
Integrin-independent role of CalDAG-GEFI in neutrophil chemotaxis.
Wagner et al., Boston, United States. In J Leukoc Biol, 2010
CalDAG-GEFI helps regulate neutrophil chemotaxis, independent of its established role in integrin activation, through a mechanism that involves actin cytoskeleton and cellular polarization.
Identification of the gene regulatory region in human rasgrp2 gene in vascular endothelial cells.
Hori et al., Kure, Japan. In Biol Pharm Bull, 2009
analyzed the 5'-flanking region of rasgrp2 gene by a luciferase assay, which revealed that not only a promoter but also silencer regions were present upstream of D1E, suggesting rasgrp2 expression is controlled by a combination of promotion and repression
