**Background of Armadillo Repeat-Containing Protein 7 (ARMC7)**
ARMC7 is a member of the armadillo (ARM) repeat protein family, characterized by tandem repeats of a conserved ~40-amino acid motif. These proteins are involved in diverse cellular processes, including signaling, cytoskeletal organization, and intracellular transport. ARMC7. localized to mitochondria and associated with ciliary transition zones, is implicated in mitochondrial protein import and cilia-related functions.
Structurally, ARMC7 interacts with mitochondrial translocase complexes, suggesting a role in maintaining mitochondrial homeostasis. Studies link ARMC7 to sperm formation, as Armc7-deficient mice display impaired spermatogenesis and male infertility due to disrupted mitochondrial sheath assembly in sperm. It also participates in the ubiquitin-proteasome system, potentially regulating protein quality control.
Emerging evidence associates ARMC7 with tumorigenesis. In hepatocellular carcinoma (HCC), ARMC7 is reported to act as a tumor suppressor by destabilizing the oncogenic transcription factor YAP1 through E3 ubiquitin ligase complexes. Reduced ARMC7 expression in HCC correlates with poor prognosis and cancer progression. Additionally, ARMC7 may influence DNA damage response pathways, though mechanistic details remain under investigation.
Despite these insights, ARMC7’s full biological scope and regulatory mechanisms are not fully elucidated. Current research focuses on its dual roles in mitochondrial integrity and cancer, aiming to explore therapeutic targets for related pathologies such as infertility and malignancies.
