Fig. 1. Structure and sequence of the hydra Kazal1 protein. (A) Schematic view of the Kazal1 cDNAs and the deduced Kazal1 protein structure. The gray box highlights the divergent non-coding 5' sequences of H. magnipapillata. (B) Alignment of Kazal1 to selected KD-containing sequences. The signal peptide is underlined and the cleavage site indicated by an inverted triangle.
