Study of telomere function in germ cells, relevant to the regulations of homologous recombination and telomere length maintenance across generations

The length of telomeric DNA is a critical determinant factor for aging and cancer development. In germ cells, the activation of a telomerase-dependent telomere-lengthening pathway is thought to be important in order to maintain telomeric DNA across generations, but the molecular mechanisms involved in this pathway, i.e: how and when telomerase is activated in germ cells, are largely unknown. A DNA-binding protein complex called shelterin constitutively binds telomeric DNA. However, my recent studies have suggested that a multi-subunit DNA-binding complex, TERB1-TERB2-MAJIN, takes over telomeric DNA from shelterin in mammalian germ cells in order to facilitate homologous recombination. These…
