Atomic structure of DUSP26
Template:ABSTRACT PUBMED 23298255
Function
[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]
About this Structure
4hrf is a 4 chain structure with sequence from Homo sapiens. Full crystallographic information is available from OCA.
