Recombinant human EF-hand domain-containing protein (C3orf25), also referred to as ESCO2 or EFHC2, is a conserved eukaryotic protein implicated in chromosomal stability and transcriptional regulation. It harbors tandem EF-hand motifs, helical structural domains known for calcium ion binding, suggesting potential roles in calcium-dependent signaling or molecular scaffolding. The protein is ubiquitously expressed, with elevated levels observed in brain, testis, and proliferating tissues.
Functionally, C3orf25 interacts with components of the sister chromatid cohesion complex, particularly acetyltransferase ESCO2, contributing to proper chromosome segregation during mitosis. Mutations in this gene are associated with Roberts syndrome, a rare developmental disorder characterized by limb malformations and craniofacial defects, linking its dysfunction to impaired DNA repair and cell cycle progression. Recent studies propose additional involvement in neuronal processes, as EF-hand domains may regulate synaptic plasticity through calcium-mediated pathways.
Despite structural characterization of its Ca²⁺-binding capacity, the precise molecular mechanisms and full interactome remain incompletely mapped. Current research focuses on elucidating its dual roles in mitotic fidelity and potential neurodevelopmental functions, with therapeutic implications for genetic disorders and cancer. Advanced proteomic and CRISPR-based approaches are progressively uncovering context-dependent post-translational modifications that fine-tune its activity across cellular compartments.
