Summary
Enables enzyme activator activity and telomerase inhibitor activity. Involved in box C/D RNA 3'-end processing and negative regulation of telomere maintenance via telomerase. Located in nucleolus and nucleoplasm. Used to study cancer. Orthologous to human PINX1 (PIN2 (TERF1) interacting telomerase inhibitor 1). [provided by Alliance of Genome Resources, Apr 2022]
