FAM96B (Family With Sequence Similarity 96 Member B) is a conserved eukaryotic protein implicated in diverse cellular processes, including iron-sulfur (Fe-S) cluster biogenesis, cell cycle regulation, and DNA repair. It belongs to the FAM96 protein family and shares structural homology with prokaryotic proteins involved in Fe-S cluster assembly, suggesting an evolutionarily conserved role in metalloprotein homeostasis. Structurally, FAM96B contains a conserved N-terminal domain critical for binding partner interactions and a C-terminal region proposed to participate in protein complex formation.
Functionally, FAM96B interacts with MITD1 (Megalencephalic Leukoencephalopathy with Subcortical Cysts 1 Domain-Containing Protein), forming a complex that regulates the G1/S cell cycle transition by modulating E2F transcription factors. Additionally, studies link FAM96B to the CIA (Cytosolic Iron-sulfur cluster Assembly) machinery, where it facilitates Fe-S cluster transfer to apoproteins, essential for enzymes involved in DNA replication and repair, such as DNA polymerases and helicases. This highlights its dual role in metabolic and genomic stability.
Dysregulation of FAM96B has been associated with pathological conditions. Reduced expression correlates with tumor progression in cancers like hepatocellular carcinoma and gastric cancer, suggesting a tumor-suppressive role. Mechanistically, FAM96B loss may impair Fe-S cluster-dependent enzyme activity, leading to genomic instability or altered iron metabolism, both hallmarks of cancer. Its involvement in cell cycle checkpoints further underscores its potential as a therapeutic target.
Recombinant FAM96B protein is typically produced in *E. coli* or mammalian expression systems, often fused with tags (e.g., His-tag) for purification. It serves as a critical tool for *in vitro* studies, including protein interaction assays, enzymatic activity analyses, and structural investigations. Ongoing research aims to delineate its precise molecular mechanisms and explore its diagnostic or therapeutic potential in diseases linked to Fe-S cluster dysregulation or cell cycle anomalies.
