Figure 1: Alignments of the deduced amino acid sequence of cTGF-β1 with its homologues in other species.

Numbers on the right of the sequences indicate the amino acid positions. Gaps are noted with hyphens. The mature peptide portion is noted with the arrow. The signal peptide region, RGD integrin-binding site, RRKR cut site, nine conserved cysteine residues, and conserved proline and glycine at positions 36 and 46 of the mature peptide are marked in red, blue, brown, yellow, green and grey, respectively. The GenBank accession numbers of the detected species are as follows: D. rerio (NP_878293.1); C. alburnus (AIS23633.1); O. mykiss (NP_001268295.1); T. rubripes (BAM44873.1); E. coioides (ACV96791.1); C. carpio (Q9PTQ2.1); S. salar (ACN11294.1); M. musculus (NP_035707.1); H. sapiens (NP_000651.3); and A. mexicanum (ABX24523.1).
