telombin(redirected from protection of telomeres protein 1)
telombinA nuclear protein encoded by POT1 on chromosome 7q31.33, which plays a key role in telomere maintenance as a component of the telomerase ribonucleoprotein complex. This complex binds the TTAGGG repeats of telomeres, regulating telomere length and protecting the chromosome ends from inappropriate processing by DNA repair mechanisms.
