Epithelial cell transforming sequence 2 oncogene

ECT2
The protein encoded by this gene is a transforming protein that is related to Rho-specific exchange factors and yeast cell cycle regulators. The expression of this gene is elevated with the onset of DNA synthesis and remains elevated during G2 and M phases. In situ hybridization analysis showed that expression is at a high level in cells undergoing mitosis in regenerating liver. Thus, this protein is expressed in a cell cycle-dependent manner during liver regeneration, and is thought to have an important role in the regulation of cytokinesis.

Papers on ECT2
ECT2 amplification and overexpression as a new prognostic biomarker for early-stage lung adenocarcinoma.
New
Noguchi et al., Tsukuba, Japan. In Cancer Sci, 03 Mar 2014
Array-CGH demonstrated frequent amplification at chromosome 3q26, and among the 7 genes located in this region, we focused on the epithelial cell transforming sequence 2 (ECT2) oncogene, as ECT2 amplification was detected only in invasive adenocarcinoma, and not in in situ carcinoma.
Pebble/ECT2 RhoGEF negatively regulates the Wingless/Wnt signaling pathway.
New
Bejsovec et al., Durham, United States. In Development, Dec 2013
We have discovered a new mechanism for regulating the Wnt pathway: activity of a Rho guanine nucleotide exchange factor (GEF) encoded by pebble (pbl) in Drosophila and ECT2 in humans.
E-cadherin supports steady-state Rho signaling at the epithelial zonula adherens.
New
Gomez et al., Brisbane, Australia. In Differentiation, Oct 2013
This impact on Rho signaling was accompanied by reduced junctional localization of the Rho GEF ECT2 and the centralspindlin complex that recruits ECT2.

Hassan et al., Wayne, United States. In J Perinat Med, Oct 2013
Thirteen genes that encode proteins involved in host defense (DEFA4, BPI, CTSG, LCN2), tight junctions in blood-brain barrier (EMP1) and liver regeneration (ECT2) were differentially expressed in both early- and late-onset PE.

At an initiator/catalyst molar ratio of 10/1 and a TSU/CL weight ratio of 1/4, a ketal-carrying copolymer (ECT2-CK) with Mn of 52 kDa and a ketal content of 15 mol.% was obtained.
Integrated genomic, transcriptomic, and RNA-interference analysis of genes in somatic copy number gains in pancreatic ductal adenocarcinoma.

Moffat et al., Toronto, Canada. In Pancreas, Aug 2013
CONCLUSIONS: Among the candidate genes from the integrative analysis, ECT2 was found to have significantly higher essentiality in specific PDAC cell lines with genomic gains at the 3q26.3

Rajasekaran et al., Newark, United States. In Mol Pharm, Jul 2013
NPs with an average diameter of 110 nm were assembled from an amphiphilic block copolymer of poly(ethylene glycol) (PEG) and poly(ε-caprolactone) (PCL) bearing pendant cyclic ketals (ECT2).
Aurora B but not rho/MLCK signaling is required for localization of diphosphorylated myosin II regulatory light chain to the midzone in cytokinesis.
Hosoya et al., Hiroshima, Japan. In Plos One, 2012
Here, we showed that depletion of the Rho signaling proteins MKLP1, MgcRacGAP, or ECT2 inhibited the localization of 1P-MRLC to the contractile ring but not the localization of 2P-MRLC to the midzone.
Expression of the PTTG1 oncogene is associated with aggressive clear cell renal cell carcinoma.

Changes in Ect2 localization couple actomyosin-dependent cell shape changes to mitotic progression.
GeneRIF
Baum et al., London, United Kingdom. In Dev Cell, 2012
find that Ect2 first becomes active in prophase, when it is exported from the nucleus into the cytoplasm, activating RhoA to induce the formation of a mechanically stiff and rounded metaphase cortex
Centralspindlin and α-catenin regulate Rho signalling at the epithelial zonula adherens.

Centralspindlin recruits the RhoGEF, ECT2, to activate Rho and support junctional integrity through myosin IIA.
Role of RhoA-specific guanine exchange factors in regulation of endomitosis in megakaryocytes.
GeneRIF
Krause et al., New Haven, United States. In Dev Cell, 2012
It was shown that the guanine exchange factors GEF-H1 and ECT2 must be downregulated for megakaryote polyploidization. The first (2N-4N) endomitotic cycle requires GEF-H1 downregulation, whereas subsequent cycles (>4N) require ECT2 downregulation.
