| Abstract: |
The invention is directed to A-lineage conotoxin peptides, which are conotoxin peptides that have strong homology in the signal sequence and the 3'-untranslated region of the genes coding for these peptides to the sequences in the α-conotoxin peptides. The A-lineage conotoxin peptides include the α-conotoxin peptides, the α-conotoxin-like peptides and the .kappa.-conotoxin peptides, described further below. The α-conotoxin-peptides generally share a "core" sequence motif. This core sequence is termed the α 3/5 core and is represented as Cys-Cys-Xaa-Xaa-Xaa-Cys-Xaa-Xaa-Xaa-Xaa-Xaa-Cys (SEQ ID NO: 1). The α-conotoxin-like peptides generally share a core sequence termed the α 4/7 core and is represented as Cys-Cys-Xaa-Xaa-Xaa-Xaa-Cys-Xaa-Xaa-Xaa-Xaa-Xaa-Xaa-Xaa-Cys (SEQ ID NO: 2). The .kappa.-conotoxin peptides generally have a core sequence termed the .kappa.7/2/1/3 core and is represented as Cys-Cys-Xaa-Xaa-Xaa-Xaa-Xaa-Xaa-Xaa-Cys-Xaa-Xaa-Cys-Xaa-Cys-Xaa-Xaa-Xaa-Cys (SEQ ID NO: 3).

What is claimed is:
1. A process for identifying nucleic acids encoding A-lineage conotoxin peptides which comprises obtaining a sample containing Conus nucleic acid; subjecting said nucleic acid to amplification using the primers 5'-TCTGCGAATGGGCATGCGGATGATGTT-3' (SEQ ID NO:52) and 5'-TGCTCCAACGTCGTGGTTCAGAGGGTC-3') (SEQ ID NO:53) to form amplification products; and identifying said amplification products.
