NCBI Protein Information
Nucleic acid-binding, OB-fold-like protein
NCBI Summary
Encodes a protein with similarity to yeast STN1, an OB fold protein involved in protecting yeast telomeres. In Arabidopsis, loss of STN1 function mutations exhibit gross morphological abnormalities and defects in telomere architecture and maintenance. STN1 likely plays a role in telomere end capping.

UniProt Comments
Component of the CST complex, a complex that binds to single-stranded DNA and is required to protect telomeres from DNA degradation. The CST complex binds single-stranded DNA with high affinity in a sequence-independent manner, while isolated subunits bind DNA with low affinity by themselves (PubMed:19064932). Associates with enzymatically active telomerase (PubMed:25329641). Plays a genomewide role in DNA replication and facilitates re-replication at non-telomeric loci (PubMed:25299252).
