Target

  • Function

    Converts angiotensin I to angiotensin II by release of the terminal His-Leu, this results in an increase of the vasoconstrictor activity of angiotensin. Also able to inactivate bradykinin, a potent vasodilator. Has also a glycosidase activity which releases GPI-anchored proteins from the membrane by cleaving the mannose linkage in the GPI moiety.

  • Tissue specificity

    Ubiquitously expressed, with highest levels in lung, kidney, heart, gastrointestinal system and prostate. Isoform Testis-specific is expressed in spermatocytes and adult testis.

  • Involvement in disease

    Ischemic stroke (ISCHSTR) [MIM:601367]: A stroke is an acute neurologic event leading to death of neural tissue of the brain and resulting in loss of motor, sensory and/or cognitive function. Ischemic strokes, resulting from vascular occlusion, is considered to be a highly complex disease consisting of a group of heterogeneous disorders with multiple genetic and environmental risk factors. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
    Renal tubular dysgenesis (RTD) [MIM:267430]: Autosomal recessive severe disorder of renal tubular development characterized by persistent fetal anuria and perinatal death, probably due to pulmonary hypoplasia from early-onset oligohydramnios (the Potter phenotype). Note=The disease is caused by mutations affecting the gene represented in this entry.
    Microvascular complications of diabetes 3 (MVCD3) [MIM:612624]: Pathological conditions that develop in numerous tissues and organs as a consequence of diabetes mellitus. They include diabetic retinopathy, diabetic nephropathy leading to end-stage renal disease, and diabetic neuropathy. Diabetic retinopathy remains the major cause of new-onset blindness among diabetic adults. It is characterized by vascular permeability and increased tissue ischemia and angiogenesis. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
    Intracerebral hemorrhage (ICH) [MIM:614519]: A pathological condition characterized by bleeding into one or both cerebral hemispheres including the basal ganglia and the cerebral cortex. It is often associated with hypertension and craniocerebral trauma. Intracerebral bleeding is a common cause of stroke. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.

In Western blot, ab75762 was shown to bind specifically to Angiotensin Converting Enzyme 1. A band was observed at 170 kDa in wild-type SKNFI cell lysates with no signal observed at this size in Ace knockout cell line. To generate this image, wild-type and Ace knockout SKNFI cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in fluorescent western blot (TBS-based) blocking solution before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L 800CW and Goat anti-Mouse IgG H&L 680RD at 1/20000 dilution.

    Answer

    Wie besprochen habe ich eine kostenlose Ersatzlieferung für Sie in Auftrag gegeben. Sie hat die Referenznummer 1155271 und sollte morgen bei Ihnen ankommen.

    Das Molekulargewicht kann man folgendermaßen errechnen: Öffnen Sie die SwissProt Link auf unserem Datenblatt für das Maus Protein (http://www.uniprot.org/uniprot/P09470), und rollen Sie die Seite einmal bis zum Abschnitt "Sequence annotation (Features)" herunter. Dort finden Sie die Angaben zum "Molecule processing" ,in welchen die Länge und Positionen der einzelnen Protein Ketten beschrieben werde. Wenn Sie die jeweilige Position öffnen, gelangen Sie zur FASTA Sequenz ( in dem Kasten oben links).

    Desweiteren oeffnen Sie den Molekular Gewicht/ pI Rechner unter dem folgenden Link http://web.expasy.org/compute_pi/

    In diesen fügen Sie die FASTA Sequenz ein, und lassen das Gewicht berechnen.

    Ich wünsche Ihnen viel Erfolg für Ihr Projekt. Bitte zögern Sie nicht, sich wieder bei uns zu melden, falls Sie weitere Fragen haben.

    Answer

    Vielen Dank für Ihren Anruf und dafür, dass Sie sich die Zeit genommen haben, unseren Fragebogen auszufüllen.



    Ich möchte folgende Bemerkungen zu Ihrem Protokoll machen:

    1. Ich denke, Sie detektieren das richtige Protein, da zwei so unterschiedliche Antikörper das gleiche Signal zeigen. Dies kann am veränderten Stoffwechsel der Zellen liegen, die Sie verwenden ( schließlich handelt es sich hier laut ATCC um ein Endothelioma).


    2. Schauen Sie sich bitte einmal das Dokument an, welches ich an diese Email gehängt habe: Dieses Dokument zeigt sehr schön, wie das Gelsystem das Laufverhalten beeinflußen kann.

    3. Eine Abweichung von bis zu 10% von der erwarteten Groesse kann durchaus als normal angesehen werden.

    4. Es gibt zwei Formen dieses Proteins, die lösliche und die zelluläre Form. Die lösliche From ist ca 10 kDa leichter als die zellulare (138 kDa vs 148 kDA).

    5. Da Sie leider mit einem System arbeiten (Odyssey), ist es schwierig Veränderungsvorschläge zu Ihrem Blot zu machen. Es würde mich allerdings interessieren, ob Sie via Chemolumineszenz oder Fluoreszenz detektieren.

    6. Um auszuschließen, dass Sie das falsche Protein detektieren, möchte ich Ihnen ein Maushirn Lysat als Positiv- bzw Vergleichsprobe kostenlos zusenden. Bitte lassen Sie mich wissen, ob Sie damit einverstanden sind.

    Vielen Dank für Ihren Anruf.

    Es tut mir leid zu hören, dass Sie Probleme mit diesen Antikörpern haben.

    Ich habe unseren Fragebogen als Word-Dokument an diese E-Mail angehängt. Durch das Ausfüllen des Fragebogens erhalten wir alle nötigen Informationen über Ihre Proben und Ihr Protokoll. Sobald Sie dieses Formular an uns zurückgeschickt haben, werden wir uns Ihr Protokoll ansehen und möglichst Veränderungsvorschläge machen, die Ihre Ergebnisse verbessern werden. Falls sich herausstellt, dass der Antikörper nicht so funktioniert, wie auf dem Datenblatt beschrieben und er innerhalb der letzten 180 Tage gekauft wurde, werden wir Ihnen gerne einen Ersatz oder eine Gutschrift schicken.

    Can Angiotensin Converting Enzyme 1 antibody [EPR2757] (ab75762) be applicated for detecting  human testicular ACE(tACE or germinal ACE)? Thanks a lot! 我可以Angiotensin Converting Enzyme 1 antibody [EPR2757] (ab75762)抗体检测睾丸特异的ACE（tACE，or germinal ACE）吗？谢谢。 ----------------

    Answer

    Thank you for contacting us. The immunogen of ab75762 shares 57% identity with the testis-specific isoform of Angiotensin Converting Enzyme 1. Thus, I would not predict that it would recognize this isoform. I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
