Armadillo repeat-containing proteins (ARMCs) are important for various cellular functions like adhesion, signaling, and regulating cellular structures, with ARMC6 being significant in primates but its specific roles were previously unclear.
Recent experiments show that ARMC6 binds to DNA promoter sequences of cancer-related genes and to telomeric RNA, suggesting involvement in chromosomal maintenance via recognition of G-quadruplex structures.
Overexpression of ARMC6 in human cell lines leads to altered expression of oncogenic and telomerase-related genes, highlighting its potential role in linking gene regulation with telomeric chromatin rearrangement.
