Structure of Mortalin-NBD with N6-propargyladenosine-5'-diphosphate
Structural highlights
FunctionGRP75_HUMAN Implicated in the control of cell proliferation and cellular aging. May also act as a chaperone. Publication Abstract from PubMedOur early efforts to find a covalent inhibitor of mortalin, a member of the 70 kD heat shock protein (Hsp70) family, led us to solve the structure of the mortalin nucleotide-binding domain (NBD) in complex with N6-propargyladenosine-5'-diphosphate. The acquired structure emphasizes the ability of the nucleotide-binding pocket to accommodate modified ADP compounds. A library of ADP analogues modified at either the 2- or N6-positions of adenosine were screened against the mortalin-NBD. Competitive inhibition and binding assays of the analogues demonstrate that modifications at the 2- or N6-positions have potential to bind and inhibit mortalin uniquely compared to other Hsp70 homologs, and that modifications at the 2-position confer the greatest selectivity in binding and inhibition of the mortalin-NBD.
