Also known as: ISD11; CGI-203; COXPD19; C6orf149
Summary: The protein encoded by this gene is found in both mitochondria and the nucleus, where it binds cysteine desulfurase and helps free inorganic sulfur for Fe/S clusters. Disruption of this gene negatively impacts mitochondrial and cytosolic iron homeostasis. [provided by RefSeq, Sep 2016]

In this work, the structure of the human mitochondrial ACP-ISD11 heterodimer was determined at 2.0 A resolution.
Title: Structure of the Human ACP-ISD11 Heterodimer.
The molecular structure of the human mitochondrial cysteine desulfurase complex consisting of two copies each of NFS1, ISD11, and acyl carrier protein has been described.
Title: Architectural Features of Human Mitochondrial Cysteine Desulfurase Complexes from Crosslinking Mass Spectrometry and Small-Angle X-Ray Scattering.
analysis of the NFS1-ISD11-ACP (SDA) complex forms the core of the iron-sulfur (Fe-S) assembly complex and associates with assembly proteins ISCU2, frataxin (FXN), and ferredoxin to synthesize Fe-S clusters
Title: Structure of human Fe-S assembly subcomplex reveals unexpected cysteine desulfurase architecture and acyl-ACP-ISD11 interactions.
Human Isd11 (ISD11) is a helical protein which exists in solution as an equilibrium between monomer, dimeric and tetrameric species when in the absence of human Nfs1 (NFS1). Recombinant ISD11 expressed in E. coli co-purifies with the bacterial orthologue of NFS1, IscS.
Title: The Eukaryotic-Specific ISD11 Is a Complex-Orphan Protein with Ability to Bind the Prokaryotic IscS.
The NFS1/ISD11 complex further interacts with scaffold protein ISCU and regulator protein frataxin, thereby forming a quaternary complex for Fe-S cluster formation.
Title: The N-Terminus of Iron-Sulfur Cluster Assembly Factor ISD11 Is Crucial for Subcellular Targeting and Interaction with l-Cysteine Desulfurase NFS1.
Molecular dynamics flexible fitting of protein structures docked into the EM map of the model revealed a [FXN(42-210)]24.[NFS1]24.[ISD11]24.[ISCU]24 complex, consistent with the measured 1:1:1:1 stoichiometry of its four components.
Title: Architecture of the Human Mitochondrial Iron-Sulfur Cluster Assembly Machinery.
Our findings highlight that the ISD11 R68A/R68L mutation display reduced affinity to form a stable subcomplex with NFS1, and thereby fails to prevent NFS1 aggregation resulting in impairment of the Fe-S cluster biogenesis
Title: Mapping Key Residues of ISD11 Critical for NFS1-ISD11 Subcomplex Stability: IMPLICATIONS IN THE DEVELOPMENT OF MITOCHONDRIAL DISORDER, COXPD19.
Homozygous mutation in LYRM4 was reported in two patients with combined oxidative phosphorylation deficiency.
Title: Mutations in LYRM4, encoding iron-sulfur cluster biogenesis factor ISD11, cause deficiency of multiple respiratory chain complexes.
LYRM4 downregulation may be one of the mechanisms involved in inefficient oxidative phosphorylation and oxidative stress, increasingly recognised as contributors to schizophrenia pathogenesis.
Title: Promoter polymorphisms in two overlapping 6p25 genes implicate mitochondrial proteins in cognitive deficit in schizophrenia.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
