Summary: This gene encodes a protein that is involved in telomere function. This protein is one of six core proteins in the telosome/shelterin telomeric complex, which functions to maintain telomere length and to protect telomere ends. Through its interaction with other components, this protein plays a key role in the assembly and stabilization of this complex, and it mediates the access of telomerase to the telomere. Multiple transcript variants encoding different isoforms have been found for this gene. This gene, which is also referred to as TPP1, is distinct from the unrelated TPP1 gene on chromosome 11, which encodes tripeptidyl-peptidase I. [provided by RefSeq, Jul 2008]
Annotation information: Note: TPP1 (Gene ID: 1200) and ACD (Gene ID: 65057) share the TPP1 symbol/alias in common. TPP1 is a widely used alternative name for ACD, shelterin complex subunit and telomerase recruitment factor (ACD), which can be confused with the official symbol for TPP1 (tripeptidyl peptidase 1, GeneID 1200).
