Schematic drawing of the TGF-β2 protein (LAP, latency-associated peptide) with the alternatively spliced exon 2B. Nucleotide and amino acid sequence of exon 2B (underlined capital letters) of the variant TGF-β2B are shown. Additionally, the partial sequence of TGF-β2 without exon 2B is shown. The sequence of TGF-β2 was not available for oryctolagus cuniculus. Underlined amino acids indicate amino acid exchange at the splice site junction due to the alternative splicing. Bold letters mark the amino acid and nucleotide exchanges with respect to the human sequence. Arrows indicate the exon boundaries. The accession numbers are also given. (hs, homo sapiens; pt, pan troglodytes; mmu, macaca mulatta; cf, canis familiaris; oc, oryctolagus cuniculus; mm, mus musculus; rn, rattus norvegicus).
