mass spectrometry analysis of purified human autotaxin alpha isoform reveals a large peak around 105300 Da. This could be due to the presence of glycan structures on the protein. The 66-kDa band disappears under nonreduced conditions and is not detected by mass spectrometry analysis of the native molecule. N-terminal sequencing analysis of the second band (66 kDa) gives the sequence KVAPKRR corresponding to position 341 of the protein. alpha isoform is indeed cleaved between Arg340 and Lys341 Homo sapiens
