- * Synaptobrevin signature *
- ***************************
-
- Synaptobrevin [1] is an intrinsic membrane protein of small synaptic vesicles
- whose function is not yet known, but which is highly conserved in mammals,
- electric ray (where its is known as VAMP-1), Drosophila and yeast [2]. In
- mammals and yeast (genes SNC1 and SNC2) there are two closely related forms of
- synaptobrevin [3].
-
- Structurally synaptobrevin consist of a N-terminal cytoplasmic domain of from
- 90 to 110 residues, followed by a transmembrane region, and then by a short
- (from 2 to 22 residues) C-terminal intravesicular domain.
-
- As a signature pattern for synaptobrevin we selected a highly conserved
- stretch of residues located in the central part of the sequence.
-
- -Consensus pattern: R-x-N-[LIVM]-[DEN]-K-V-x-[DE]-R-x-[EQ]-[KR]-[LIVM]-[ST]-x-
- [LIVM]-x-[DE]-[KR]-A-[DE]
- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: NONE.
- -Last update: June 1994 / Pattern and text revised.
