Table 1. Characteristics of the newly identified ASM splice variants.

ASM variant	Accession No.	Alternative splicing event	Affected exon	Orthologous transcripts	Impact on protein structure
ASM-5	HQ132746	Acceptor downstream of exon 2	Exon 3	-	Disruption of catalytic domain
ASM-6	HQ132747	Intron between exon 5 and 6	Exon 6	Pan troglodytes	Disruption of C-terminal domain;
				Macaca mulatta	Specific peptide
ASM-7	HQ132748	Intron between exon 2 and 3	Exon 2	Pongo abelii	Disruption of catalytic and
					C-terminal domain; Specific peptide

Exon numbers are based on the full-length ASM-1 transcript.
