Crystal structure of catalytic domain of dual specificity phosphatase 26, MS0830 from Homo sapiensCrystal structure of catalytic domain of dual specificity phosphatase 26, MS0830 from Homo sapiens
Structural highlights
2e0t is a 1 chain structure with sequence from Homo sapiens. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
DUS26_HUMAN Inactivates MAPK1 and MAPK3 which leads to dephosphorylation of heat shock factor protein 4 and a reduction in its DNA-binding activity. Inhibits MAP kinase p38 by dephosphorylating it and inhibits p38-mediated apoptosis in anaplastic thyroid cancer cells. Can also induce activation of MAP kinase p38 and c-Jun N-terminal kinase (JNK).[1][2][3][4]
