Nucleotide and deduced amino acid sequences of Syt1. The nucleotide (black) and deduced amino acid (blue) sequences are shown and numbered on the left. The nucleotide sequence is numbered from the 5’ end. The first methionine (M) is the first deduced amino acid. Two protein kinase C2 conserved regions (amino acids 157–259, 288–402) are shaded. The start codons (ATG) and the stop codons (TAA) are marked in bold red.
