POT1 Gene Summary [Human]

This gene is a member of the telombin family and encodes a nuclear protein involved in telomere maintenance. Specifically, this protein functions as a member of a multi-protein complex that binds to the TTAGGG repeats of telomeres, regulating telomere length and protecting chromosome ends from illegitimate recombination, catastrophic chromosome instability, and abnormal chromosome segregation. Increased transcriptional expression of this gene is associated with stomach carcinogenesis and its progression. Alternatively spliced transcript variants have been described.

Protein Domains

A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in human POT1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
  • protein interaction domain
  • DNA binding domain
  • enzyme inhibitor activity
  • DNA secondary structure binding
  • oligosaccharide/oligonucleotide-binding fold
  • ssDNA-binding domain
  • protein binding
  • sequence-specific DNA binding
  • telomeric DNA binding
  • oligonucleotide/oligosaccharide-binding fold of replication protein A and class 2b aminoacyl-tRNA synthetases
  • damaged DNA binding
  • single-stranded DNA binding
  • DEAD/H-box RNA helicase binding
  • PTOP binding region
