Giant virus yields potassium channel gene that sheds light on complex protein evolution

دیوہیکل وائرس سے پوٹاشیم چینل کا جین ملا، پیچیدہ پروٹین کے ارتقا پر روشنی

विशाल वायरस से पोटैशियम चैनल का जीन मिला, जटिल प्रोटीन के विकास पर रोशनी

Giant virus yields potassium channel gene that sheds light on complex protein evolution

Key points

اہم نکات

मुख्य बातें

  • Researchers have found a gene for a tandem potassium channel in a giant DNA virus that infects marine algae.
  • The finding, published in the Proceedings of the National Academy of Sciences, supports the view that giant viruses may have played a major role in the evolution of complex proteins.
  • Tandem potassium channels help control the electrical activity of nerve cells by moving potassium ions across cell membranes.
  • محققین نے سمندری کائی کو متاثر کرنے والے ایک دیوہیکل ڈی این اے وائرس میں ٹینڈم پوٹاشیم چینل کا جین پایا ہے۔ پروسیڈنگز آف دی نیشنل اکیڈمی آف سائنسز میں شائع ہونے والی یہ دریافت اس خیال کی حمایت کرتی ہے کہ دیوہیکل وائرس پیچیدہ پروٹین کے ارتقا میں بڑا کردار ادا کر سکتے ہیں۔ ٹینڈم پوٹاشیم چینل خلیوں کی جھلیوں سے پوٹاشیم آئنز منتقل کر کے اعصابی خلیوں کی برقی سرگرمی کو کنٹرول کرنے میں مدد دیتے ہیں۔ حیران کن طور پر یہ نیا جین میزبان سے چرایا ہوا نہیں بلکہ وائرل اصل کا لگتا ہے، جس سے سائنسدانوں کی ان اہم چینلز کی ابتدا کے بارے میں سوچ بدلتی ہے۔
  • शोधकर्ताओं ने समुद्री शैवाल को संक्रमित करने वाले एक विशाल डीएनए वायरस में टैंडम पोटैशियम चैनल का जीन पाया है। प्रोसीडिंग्स ऑफ़ द नेशनल एकेडमी ऑफ़ साइंसेज़ में प्रकाशित यह खोज इस विचार का समर्थन करती है कि विशाल वायरस जटिल प्रोटीन के विकास में बड़ी भूमिका निभा सकते हैं। टैंडम पोटैशियम चैनल कोशिका झिल्लियों से पोटैशियम आयन ले जाकर तंत्रिका कोशिकाओं की विद्युत गतिविधि को नियंत्रित करने में मदद करते हैं। आश्चर्यजनक रूप से यह नया जीन मेज़बान से चुराया हुआ नहीं बल्कि वायरल मूल का लगता है, जिससे वैज्ञानिकों की इन महत्वपूर्ण चैनलों की उत्पत्ति के बारे में सोच बदलती है।

Researchers have found a gene for a tandem potassium channel in a giant DNA virus that infects marine algae. The finding, published in the Proceedings of the National Academy of Sciences, supports the view that giant viruses may have played a major role in the evolution of complex proteins. Tandem potassium channels help control the electrical activity of nerve cells by moving potassium ions across cell membranes. Strikingly, the new gene appears to be of viral origin rather than stolen from its host, which changes how scientists think about where these important channels came from.
