A diversidade de tripanossomas é atribuída a um arsenal gene vasto. HSP compreendem várias famílias que atuam como uma chaperona moleculares em condições de estresse e fisiológicas. A HSP70 em tripanossomas consiste em 9 genes: Canonical, HSP70.4, HSP70.c, GRP78, Lc2.2, HSP70.b, Grp170, HSP110 e HSP70.a. Análises filogenéticas indicam que a evolução de HSP70 segue um padrão de ramificação que coincide com a compartimentação celular. As inferências filogenéticas de Trypanosoma obtidas a partir de genes que codificam HSP70s foram compatíveis com os obtidos por gGAPDH indicando que as HSP70s são uteis como marcadores moleculares. Os genes que codificam proteínas possuindo domínio P3/alfa-cristalino (ACD) na sua estrutura atuam como chaperonas envolvidas na proliferação e migração celular, citoesqueleto, na resposta a agentes patogénicos e desenvolvimento. Nove chaperonas putativas com o ACD foram recuperadas em Trypanosoma: TryDYX1C1, TrySGT1, Tryp23A, Tryp23B, TryNudC1, TryNudC2, HSP20, TryACDP, TryACD-TPR.

The diversity of trypanosomes is attributed to a vast gene arsenal. HSP comprehends several families which acts as a molecular chaperone in stress and physiological conditions. The HSP70 in trypanosomes consists of nine genes: Canonical, HSP70.4, HSP70.c, Grp78, Lc2.2, HSP70.b, Grp170, HSP110 and HSP70.a. Phylogenetic analysis shows that the evolution of HSP70 from Trypanosoma follows branching pattern that coincides with the cellular compartmentation. Phylogenetic Inferences of Trypanosoma obtained from genes encoding HSP70s were compatible with those obtained by gGAPDH indicating that HSP70 gene is a useful molecular maker. Genes encoding proteins having p3/alpha-crystalline domain (ACD) in its structure act as chaperones and co-chaperones involved in cell proliferation and migration, cytoskeleton and in response to pathogens and development. Nine putative chaperones containing the ACD were recovered in Trypanosoma: TryDYX1C1, TrySGT1, Tryp23A, Tryp23B, TryNudC1, TryNudC2, HSP20, TryACDP, TryACD-TPR.
