Iron 0-4 aconitase 1 Mus musculus 31-56 16424901-1 2006 The generally accepted role of iron-regulatory protein 1 (IRP1) in orchestrating the fate of iron-regulated mRNAs depends on the interconversion of its cytosolic aconitase and RNA-binding forms through assembly/disassembly of its Fe-S cluster, without altering protein abundance. Iron 31-35 aconitase 1 Mus musculus 58-62 16424901-2 2006 Here, we show that IRP1 protein abundance can be iron-regulated. Iron 49-53 aconitase 1 Mus musculus 19-23 16424901-3 2006 Modulation of IRP1 abundance by iron did not require assembly of the Fe-S cluster, since a mutant with all cluster-ligating cysteines mutated to serine underwent iron-induced protein degradation. Iron 32-36 aconitase 1 Mus musculus 14-18 16424901-3 2006 Modulation of IRP1 abundance by iron did not require assembly of the Fe-S cluster, since a mutant with all cluster-ligating cysteines mutated to serine underwent iron-induced protein degradation. Iron 162-166 aconitase 1 Mus musculus 14-18 16424901-4 2006 Phosphorylation of IRP1 at S138 favored the RNA-binding form and promoted iron-dependent degradation. Iron 74-78 aconitase 1 Mus musculus 19-23 16424901-9 2006 Our results reveal a mechanism for regulating IRP1 action relevant to the control of iron homeostasis during cell proliferation, inflammation, and in response to diseases altering cytosolic Fe-S cluster assembly or disassembly. Iron 85-89 aconitase 1 Mus musculus 46-50 16424901-9 2006 Our results reveal a mechanism for regulating IRP1 action relevant to the control of iron homeostasis during cell proliferation, inflammation, and in response to diseases altering cytosolic Fe-S cluster assembly or disassembly.
