KSHV infection and hypoxia induce miR-210 independently and additively, while miR-210 modulates its target expression, ISCU, in KSHV-infected cells.(A) Data represent miR-210 relative expression in normoxic and hypoxic SLKK and SLK cells. Values are normalized to the average of normoxic SLK controls set to one. Taqman assays demonstrate that hypoxic conditions (1% O2 for 24hrs) up-regulate miR-210 in both KSHV-infected and uninfected cells (P ≤0.01, Student’s t-test). Additionally, Taqman assays show that KSHV infection alone up-regulates miR-210, in both normoxia and hypoxia (*P ≤0.05, Student’s t-test). (B) Analysis of miR-210 expression in normoxic and hypoxic SLKK cells transfected with miR-210 mimics, anti-miR-210 inhibitors or controls using Taqman assays. Bars depict the relative expression of miR-210 compared to normoxic NT controls. NT : No Transfection.

ISCU also known as the iron-sulfur cluster scaffold protein is an important player in the assembly of iron-sulfur clusters. This protein possesses a molecular mass of approximately 14 kDa and is widely expressed in mitochondria highlighting its central involvement in cellular processes dependent on these organelles. ISCU interacts with several proteins to facilitate the transfer of iron-sulfur clusters to apoproteins ensuring the proper maturation of these metalloproteins necessary for a variety of cellular functions.
Biological function summary

ISCU protein functions as an important scaffold component in the biosynthesis of iron-sulfur (Fe-S) clusters which are integral for the activity of multiple enzymatic and non-enzymatic systems. Within the mitochondria ISCU forms part of a multi-component complex that includes other scaffold proteins and necessary enzymes such as cysteine desulfurase which provides sulfur for cluster assembly. This complex orchestrates the precise coordination of metal ions and scaffold protein interactions facilitating cluster formation.

Pathways

The iron-sulfur cluster scaffold ISCU is vital in the electron transport chain and the citric acid cycle both of which are central to energy production in cells. ISCU closely interacts with proteins like frataxin which delivers iron to the scaffold and ferredoxin which is involved in electron transfer. These interactions highlight the pathway interdependence that maintains cellular bioenergetics and redox balance.

Disruptions in ISCU expression or function link to conditions such as Myopathy with exercise intolerance and Friedreich’s ataxia. Altered iron-sulfur cluster biogenesis impairs energy metabolism affecting muscle and neural tissues. ISCU's partnership with the frataxin protein becomes significant here as frataxin mutations result in similar pathological features thereby providing a potential target for therapeutic intervention in related diseases.

Target data

Isoform 1. Mitochondrial scaffold protein, of the core iron-sulfur cluster (ISC) assembly complex, that provides the structural architecture on which the [2Fe-2S] clusters are assembled (PubMed : 34824239). The core iron-sulfur cluster (ISC) assembly complex is involved in the de novo synthesis of a [2Fe-2S] cluster, the first step of the mitochondrial iron-sulfur protein biogenesis. This process is initiated by the cysteine desulfurase complex (NFS1 : LYRM4 : NDUFAB1) that produces persulfide which is delivered on the scaffold protein ISCU in a FXN-dependent manner. Then this complex is stabilized by FDX2 which provides reducing equivalents to accomplish the [2Fe-2S] cluster assembly. Finally, the [2Fe-2S] cluster is transferred from ISCU to chaperone proteins, including HSCB, HSPA9 and GLRX5 (Probable) (PubMed : 24971490, PubMed : 29576242, PubMed : 30031876, PubMed : 34824239). Exists as two slow interchanging conformational states, a structured (S) and disordered (D) form (PubMed : 23940031). May modulate NFS1 desulfurase activity in a zinc-dependent manner (PubMed : 30031876). Modulates the interaction between FXN and the cysteine desulfurase complex (PubMed : 29576242).. Isoform 2. Cytoplasmic scaffold protein, of the cytoplasmic core iron-sulfur cluster (ISC) assembly complex that provides the structural architecture on which the Fe-S clusters are assembled and may be involved in the cytoplasmic iron-sulfur protein biogenesis.
