Scientists have discovered the gene responsible for the evolution of organisms. The ancestral gene is common among all the multicellular species without which our planet would probably still have been at microorganism stage without any complex species.
Researchers have identified a large group of enzymes called protein kinases that are found in all types of complex organisms including animals, plants, and humans. Protein kinases are responsible for complex growth of cells, communication among those cells and very fast transfer of information from one part to another part.
“If the duplications and subsequent mutations of this gene during evolution did not happen, then life would be completely different today,” said Steven Pelech, a Professor at the University of British Columbia in Canada. “The most advanced life on our planet would probably still be bacterial slime.”
Complex species are made of complex eukaryotic cells that have hundreds of organelles to perform different functions that are necessary for survival of species. It is similar to different organs in human body that perform different and specific tasks.
In the study published in the Journal of Biological Chemistry, researchers have presented the discovery of gene responsible for the protein kinases. Researchers say that at the elementary level these protein are responsible for communication and transferring information throughout the cell just like neuron transfers connects and sends information in the brain, a process known as protein phosphorylation.
Study authors believe that the ability to communicate and transfer information led to the coordination among differed parts required for the evolution of intelligent species.
The study holds significance as there are many diseases (over 400) related with the problem of cell signalling. The study has given a new insight into the transfer of information among cells and scientists can use it to rectify the problem of cell signalling to cure the patient.
