- * 43 Kd postsynaptic protein signature *
- ****************************************
-
- The 43 Kd postsynaptic protein [1,2] is a peripheral membrane protein thought
- to play some role in anchoring or stabilizing the nicotinic acetylcholine
- receptor at synaptic sites. It may link the receptor to the underlying post-
- synaptic cytoskeleton, possibly by direct association with actin or spectrin.
-
- The 43 Kd protein is highly conserved across species. Two highly conserved
- regions, one encompassing the N-terminus and the other near the C-terminus,
- may be important for interaction of the protein with other components of the
- postsynaptic membrane.
-
- As a signature pattern we selected the N-terminus of the mature protein (after
- removal of the initiator methionine). The N-terminal glycine is thought to be
- myristoylated.
-
- -Consensus pattern: G-Q-D-Q-T-K-Q-Q-I
- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: NONE.
