Amino acid sequence comparisons of C. elegans and mammalian nidogens

	Nidogen domains
	G1–G2a	G1	G2	G3
NID-1 vs. nidogen-1	23 /34b	21 /38	29 /41	36 /49
NID-1 vs. nidogen-2	24 /34	26 /37	28 /38	31 /44
nidogen-1 vs. nidogen-2	44 /53	44 /52	49 /61	48 /61

^a The following amino acid residues were utilized for these comparisons: G1–G2: NID-1(22–628), nidogen-1 (29–667), nidogen-2 (31–759); G1: NID-1(22–211), nidogen-1 (29–249), nidogen-2 (31–254). G2: NID-1(348–628), nidogen-1 (375–667), nidogen-2 (472–759). G3: NID-1(1279–1584), nidogen-1 (918–1245), nidogen-2 (1085–1375). The sequences used are mouse nidogen-1 (Mann et al., 1989) and human nidogen-2 (Kohfeldt et al., 1998). 

^b Percentages of amino acid sequence identity and similarity are presented for each comparison as (%identity/%similarity).
