Ubiquitous plasma membrane protein involved in fusion of vesicles with the plasma membrane
, a member of the SNARE family of proteins, is related to syntaxin 1
. Like syntaxin 2
it is predominantly localized to the plasma membrane of a wide variety of cells. Similar to syntaxins 1, 2, and 3
, it appears to be involved in the fusion of transport vesicles with the plasma membrane.
