Clone Host Grade Applications Polyclonal Goat Affinity Purified B

Complexin-2 (CPX II; also known as synaphin-1) is a 19kD, cytosolic protein that belongs to the complexin/synaphin family of molecules. It is expressed in excitatory neurons and serves as a block against premature granule release by its binding to the cis-SNARE complex that contains SNAP25, VAMP2 and STX1A. Human Complexin-2 is 134 amino acids (aa) in length and contains one coiled-coil domain (aa 28-84) that incorporates part of a SNARE complex interaction sequence (aa 41-97). There is one potential splice variant that shows a premature truncation after Glu114. Human Complexin-2 is identical in aa sequence to that for mouse and rat Complexin-2.
