Molecular cloning of a novel member of the ADP-ribosyl cyclase family. A, multiple sequence alignment of the deduced amino acid sequences of SpARC4 and that of previously identified ADP-ribosyl cyclases from S. purpuratus (SpARC1–3). Putative cleavage sites of the predicted signal peptide and GPI anchor are marked with the filled and open arrowheads, respectively. The presence of an acidic-basic cluster of amino acids in SpARC4 is marked with a box. Conserved cysteine residues between isoforms are marked with an asterisk. B, table showing percentage sequence identities (shaded) and percentage sequence similarities (above diagonal) derived from pairwise alignments between SpARC family members.
