Schematic representation of four IgM ESTs and their relationship with the genomic sequence. Examples of the different RNA splicing found in EST database are indicated. Transcripts for secreted form of IgM (OLKI20J14) with four Cμ domains and for transmembrane IgM (OLKI53H23) with two Cμ and transmembrane domains are shown. Non coding transcripts (ncRNA) were found too, these included a sequence at the 5'JH region named exon 0 (*) and have stop codons in the three reading frames.
