text: Several hnRNPs interact with telomeres, which protect the ends of chromosomes from deterioration and are often associated with cell longevity. hnRNP D associates with the G-rich repeat region of the telomeres, possibly stabilizing the region from secondary structures which would inhibit telomere replication.
  hnRNP has also been shown to interact with telomerase, the protein responsible for elongating telomeres and prevent their degradation. hnRNPs C1 and C2 associate with the RNA component of telomerase, which improves its ability to access the telomere.
