The ECT2 Polyclonal Antibody (PAC05622) is a powerful tool for researchers studying the role of ECT2, a key regulator of cell division and cytokinesis, in various biological processes. The antibody, produced in rabbits, exhibits high specificity and reactivity towards human samples, making it an excellent choice for Western blot applications. By targeting the ECT2 protein, this antibody enables precise detection and analysis of ECT2 expression in different cell types, offering valuable insights for studies in cell biology and cancer research.ECT2, also known as Epithelial Cell Transforming Sequence 2, is crucial for coordinating the intricate process of cell division and ensuring accurate segregation of genetic material during mitosis.
Dysregulation of ECT2 has been linked to abnormal cell proliferation and tumorigenesis, highlighting its importance in cancer development and progression. Investigating the molecular mechanisms underlying ECT2 function is key to unraveling its role in disease pathogenesis and identifying potential therapeutic targets for cancer treatment.In summary, the ECT2 Polyclonal Antibody (PAC05622) provides researchers with a precise and reliable tool to explore the functions of ECT2 in cellular processes and disease states. Its ability to target ECT2 specifically in human samples makes it an indispensable asset for elucidating the molecular pathways governed by ECT2 and its implications in cancer biology.
IHC image of PACO56222 diluted at 1:100 and staining in paraffin-embedded human kidney tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a biotinylated secondary antibody and visualized using an HRP conjugated SP system.

Background:
Guanine nucleotide exchange factor (GEF) that catalyzes the exchange of GDP for GTP. Promotes guanine nucleotide exchange on the Rho family members of small GTPases, like RHOA, RHOC, RAC1 and CDC42. Required for signal transduction pathways involved in the regulation of cytokinesis. Component of the centralspindlin complex that serves as a microtubule-dependent and Rho-mediated signaling required for the myosin contractile ring formation during the cell cycle cytokinesis. Regulates the translocation of RHOA from the central spindle to the equatorial region. Plays a role in the control of mitotic spindle assembly; regulates the activation of CDC42 in metaphase for the process of spindle fibers attachment to kinetochores before chromosome congression. Involved in the regulation of epithelial cell polarity; participates in the formation of epithelial tight junctions in a polarity complex PARD3-PARD6-protein kinase PRKCQ-dependent manner. Plays a role in the regulation of neurite outgrowth. Inhibits phenobarbital (PB)-induced NR1I3 nuclear translocation. Stimulates the activity of RAC1 through its association with the oncogenic PARD6A-PRKCI complex in cancer cells, thereby acting to coordinately drive tumor cell proliferation and invasion. Also stimulates genotoxic stress-induced RHOB activity in breast cancer cells leading to their cell death.

NCBI Summary:
The protein encoded by this gene is a guanine nucleotide exchange factor and 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. Several transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Apr 2012]
