Alternative mRNAs of the human SYBL1 gene and corresponding VAMP7 isoforms. Coding exons or their fragments are white; non coding ones are grey. Introns are not to scale. Domain architecture: Longin domain, red; SNARE motif, cyan (the conserved arginine of the polar layer is indicated by a vertical bar); transmembrane region and intravesicular tail, light green; N-terminal region of VAMP7c, grey; unknown function region of VAMP7b, magenta.
