FIG. 1.

Characterization of the cDNA for mouse NK1. A schematic (top) comparison of mouse HGF/SF and the NK1 splicing variant is shown. The hatched boxes represent the signal peptide regions. The black boxes labeled K1 through K4 represent kringle domains. Below the schematic is a sequence comparison of mouse and human HGF/SF exon-intron junctions and the modified translation producing the NK1 alternative splice variants. The position of the exon-intron junction for the murine NK1 is based on the mouse HGF/SF cDNA sequence (14) and the human NK1 sequence (4). a.a., amino acids. ∗, translational stop codon.
