SNAREs are integral membrane proteins (v-SNAREs on vesicles, t-SNAREs on the target organelles) and are thought to provide specificity to the fusion process1â5. It has been suggested that Sec17p and SeclSp bind to v-SNARE/t-SNARE complexes and mediate the membrane fusion event1â3.
In 2015, 4,976 people died in motorcycle crashes, up 8.3 percent from 4,594 in 2014, according to the National Highway Traffic Safety Administration (NHTSA). In 2014, motorcyclists were 27 times more likely than passenger car occupants to die in a crash per vehicle mile traveled, and almost five times more likely to be injured.
Maintaining control is harder on two wheels than on four, and when crashes occur, motorcyclists are at greater risk of serious injury or death because they don't have an enclosed vehicle to protect them.elmets decrease the severity of head injuries and the likelihood of death. The federal government estimates that wearing a helmet reduces the risk of dying in a crash by 37 percent. Unhelmeted riders are 3 times more likely than helmeted ones to sustain traumatic brain injuries in the event of a crash.
