Trypanosoma cruzi
expresses mucin like glycoproteins encoded by a complex multigene family. In this work, we report the transcription in
T. cruzi but not in
T. rangeli of a mucin type gene automatically annotated by the
T. cruzi genome project. The gene showed no nucleotide similarities with the previously reported
T. cruzi mucin like genes, although the computational analysis of the deduced protein showed that it has the characteristic features of mucins: a signal peptide sequence, O-glycosylation sites, and glycosylphosphatidylinositol (GPI) anchor sequence. The presence in this gene of N- terminal and C- terminal coding sequences common to other annotated mucin like genes suggests the existence of a new mucin like gene family.
