From language to literature, from music to mathematics, a single protein appears central to the formation of the long-term memories needed to learn these and all other disciplines, according to a team of researchers led by scientists at the National Institute of Child Health and Human Development of the National Institutes of Health. Their findings appear in the October 15 issue of Science.
The protein is known as mBDNF, which stands for mature brain-derived neurotrophic factor. It appears to chemically alter neurons, boosting their ability to communicate with one another. "Most of what we accomplish as human beings depends on what we learn," said Duane Alexander, M.D., Director of the National Institute of Child Health and Human Development. "This discovery brings the possibility of studying this protein system in people with disorders of learning and memory and perhaps designing new medications that might help to compensate for these problems."
The study was conducted by NICHDs Petti Pang, Ph.D, and Bai Lu, Ph.D, along with their colleagues at NICHD, Weill Medical College of Cornell University in New York City, and The Chinese University of Hong Kong. Researchers recognize two broad categories of memory--short term memory, and long term memory. Short term memory refers to the transient memories that last from minutes to hours. Long term memory refers to the ability to remember things for more than a day--sometimes for many years.

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
