The Hebrew University of Jerusalem is Israel's second-oldest university, after the Technion. The Hebrew University has three campuses in Jerusalem and one in Rehovot. The world's largest Jewish studies library is located on its Edmond J. Safra Givat Ram campus.The first Board of Governors included Albert Einstein, Sigmund Freud, Martin Buber, and Chaim Weizmann. Four of Israel's prime ministers are alumni of the Hebrew University. In the last decade, seven researchers and alumni of the University received the Nobel Prize and one was awarded the Fields Medal.According to the Academic Ranking of World Universities, the Hebrew University is the top university in Israel, overall the 59th-best university in the world, 16th in mathematics, 27th in computer science and 44th in business/economics.In 2013, the Center for World University Rankings ranked the Hebrew University 21st in the world and the top in Israel in its World University Rankings, while another survey ranked it as the 9th best university to work in, and the 2nd best outside of the United States.

Annual Review of Biochemistry | Year: 2013
Transmitter release is a fast Ca2+-dependent process triggered in response to membrane depolarization. It involves two major calcium-binding proteins, the voltage-gated calcium channel (VGCC) and the vesicular protein synaptotagmin (syt1). Ca2+ binding triggers transmitter release with a time response of conformational changes that are too fast to be accounted for by Ca2+ binding to syt1. In contrast, conformation-triggered release, which engages Ca2+ binding to VGCC, better accounts for the fast rate of the release process. Here, we summarize findings obtained from heterologous expression systems, neuroendocrine cells, and reconstituted systems, which reveal the molecular mechanism by which Ca2+ binding to VGCC triggers exocytosis prior to Ca2+ entry into the cell. This review highlights the molecular aspects of an intramembrane signaling mechanism in which a signal is propagated from the channel transmembrane (TM) domain to the TM domain of syntaxin 1A to trigger transmitter release. It discusses fundamental problems of triggering transmitter release by syt1 and suggests a classification of docked vesicles that might explain synchronous transmitter release, spontaneous release, and facilitation of transmitter release. © 2013 by Annual Reviews.
