Background

POT1 (Protection of telomeres protein 1; also POTE1) is a nuclear, 71 kDa member of the telombin family of proteins.  It is ubiquitously expressed, and binds single stranded DNA, TRF2, and TPP1 at the end of chromosomes.  This stabilizes chromosome ends and protects against unwarranted activation of DNA damage programs.  Human POT1 is 634 amino acids (aa) in length.  It contains two N-terminal DNA binding OB regions (aa 1-300) and a C-terminal TPP-1 dimerization domain (aa 301-634).  There are multiple isoform variants.  There is a potential alternate start site at Met132, plus a three aa substitution for aa 43-634, a 24 aa substitution for aa 317-634, a three aa substitution for aa 457-634, and a 16 aa substitution for aa 503-634.  Over aa 159-316, human POT1 shares 71% aa identity with mouse POT1.
