Gene Gene information from NCBI Gene database.
Entrez ID 80169
Gene name CST telomere replication complex component 1
Gene symbol CTC1
Synonyms (NCBI Gene)
AAF-132AAF132C17orf68CRMCCtmp494178
Chromosome 17
Chromosome location 17p13.1
Summary This gene encodes a component of the CST complex. This complex plays an essential role in protecting telomeres from degradation. This protein also forms a heterodimer with the CST complex subunit STN1 to form the enzyme alpha accessory factor. This enzyme
