Summary
Enables telomeric DNA binding activity. Acts upstream of or within negative regulation of telomere maintenance. Located in chromosome, telomeric region. Is expressed in several structures, including brain ventricular layer; olfactory epithelium; submandibular gland primordium; thymus primordium; and vibrissa. Used to study dyskeratosis congenita. Human ortholog(s) of this gene implicated in Revesz syndrome and autosomal dominant dyskeratosis congenita 3. Orthologous to human TINF2 (TERF1 interacting nuclear factor 2).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
