S. Lawrence Zipursky
Stephen Lawrence Zipursky (born January 9, 1955 ) is an American biochemist at the University of California, Los Angeles (UCLA).
Life
Zipursky grew up in Canada . He obtained a bachelor's degree in chemistry from Oberlin College in 1977 , a master 's degree in 1979 and a Ph.D. from Jerard Hurwitz in 1981. , both at Albert Einstein College of Medicine and in Molecular Biology . From 1981 he worked as a postdoctoral fellow with Seymour Benzer at the California Institute of Technology (Caltech). In 1985 he received his first professorship at the University of California, Los Angeles (UCLA), and since 1991 he has also been doing research for the Howard Hughes Medical Institute . Today (as of 2015) he is Professor of Biochemistry at the David Geffen School of Medicine at UCLA.
Act
Zipursky uses Drosophila melanogaster as a model organism . His working group identified genes that play various roles in the development of the nervous system , for example in the differentiation of the retina or the formation of neural networks . Using a combination of biochemical and genetic approaches, the function of a large family could of membrane proteins are informed that regulate the composition of neural networks and from Dscam1 - locus encodes are. The Dscam1 proteins belong to the immunoglobulin superfamily of cell recognition molecules. Through alternative splicing , the Dscam1 locus can encode more than 19,000 different extracellular protein domains or isoforms . The cell binding between two isoforms of the same kind provokes a repulsive effect between the cells. Because each nerve cell a unique pattern of Dscam1 proteins expressed , a "self-avoiding" is mediated, which is essential for the development of neural networks.
