Latest Vesicle fusion Stories
The protein that has long been suspected by scientists of being the master switch allowing brains to function has now been verified by an Iowa State University researcher. Yeon-Kyun Shin, professor of biochemistry, biophysics and molecular biology at ISU, has shown that the protein called synaptotagmin1 (Syt1) is the sole trigger for the release of neurotransmitters in the brain. Prior to this research, Syt1 was thought to be a part of the protein structure (not the sole protein) that...
By Churchward, Matthew A Rogasevskaia, Tatiana; Brandman, David M; Khosravani, Houman; Nava, Phillip; Atkinson, Jeffrey K; Coorssen, Jens R ABSTRACT The Ca^sup 2+^-triggered merger of two apposed membranes is the defining step of regulated exocytosis. CHOL is required at critical levels in secretory vesicle membranes to enable efficient, native membrane fusion: CHOL-sphingomyelin enriched microdomains organize the site and regulate fusion efficiency, and CHOL directly supports the capacity...
