2.4.1.37 | physiological function |
the deletion of exon 3 or 4, but not of exon 2 or 5, of human GTA transcripts bestows moderate Forssman glycolipid synthase activity. Strong Forssman glycolipid synthase activity is attained, in addition to GTA and GTB activities, by cointroducing one of those deletions and the replacement of the LeuGlyGly tripeptide sequence at codons 266 to 268 by GlyGlyAla substitution, i.e. to the residues of Forssman glycolipid synthase |
