S120G mutant of human nucleoside diphosphate kinase A complexed with ADP
Structural highlights
FunctionNDKA_HUMAN Major role in the synthesis of nucleoside triphosphates other than ATP. Possesses nucleoside-diphosphate kinase, serine/threonine-specific protein kinase, geranyl and farnesyl pyrophosphate kinase, histidine protein kinase and 3'-5' exonuclease activities. Involved in cell proliferation, differentiation and development, signal transduction, G protein-coupled receptor endocytosis, and gene expression. Required for neural development including neural patterning and cell fate determination.[1] [2] [3] Evolutionary Conservation Check, as determined by ConSurfDB.

This gene encodes a NDP kinase that also exhibits other properties like histidine protein kinase and interactions with proteins and DNA. The S120G mutant of NDPK-A has been identified in aggressive neuroblastomas and has been found to reduce the metastasis suppressor effect of Nm23. In order to understand the differences between the wild type and the S120G mutant, we have determined the structure of both mutant and wild type NDPK-A in complex with ADP. Our results reveal that there are no significant changes between the two enzyme versions even in the surroundings of the catalytic histidine that is required for NDP kinase activity. This suggests that the S120G mutation may affect an other protein property than NDP kinase activity.
