Multiple alignment of the nucleotide sequences of profilins.
A) Two open reading frames (ORF) are indicated by vertical arrows. Numbering of the sequence positions begins at the ATG start codon from ORF2. Reference sequences of profilin from different species previously deposited in the GenBankTM/EMBL database were highlighted in red colour. Start and stop codons are indicated by colourless boxes. Significant deletions are depicted in red boxes. B) Sequence conservation index calculated with ClustalW software, 100% conservation corresponding to the maximal height of the bar at each position, and pointed out by an asterisk in the consensus.
