Genes affected

PINX1 (HGNC:30046): (PIN2 (TERF1) interacting telomerase inhibitor 1) Enables telomerase RNA binding activity and telomerase inhibitor activity. Involved in several processes, including negative regulation of DNA biosynthetic process; positive regulation of protein localization to nucleolus; and protein localization to organelle. Acts upstream of or within telomere maintenance via telomerase. Located in several cellular components, including chromosomal region; nuclear lumen; and spindle.
