  • General notes

    Principal Names – PINX1/LPTS; PIN2-interacting protein 1; LPTL; LPTS; MGC8850; FLJ20565; 67-11-3 protein; hepatocellular carcinoma-related putative tumor suppressor. Official Gene Symbol - PINX1/LPTS (interim symbol). GenBank Accession Number – NP_060354. LocusLink ID - 54984; 72400 (mouse). Please note: We have been contacted by a researcher working with PINX1/LPTS to advise that recent research has shown that there are two splice variants of PINX1/LPTS, one at 45 kDa (full lenth) and the other at 20 kDa (C-terminus truncated). This antibody detects a band at 37kDa in Jurkat Lysate. The researcher is currently testing this antibody to confirm that the band we find at 37 kDa is infact PINX1/LPTS. We would be interested to hear back from any other researchers working with PINX1/LPTS. 11 March, 2004.

  • Function

    Microtubule-binding protein essential for faithful chromosome segregation. Mediates TRF1 and TERT accumulation in nucleolus and enhances TRF1 binding to telomeres. Inhibits telomerase activity. May inhibit cell proliferation and act as tumor suppressor.
  • Tissue specificity

    Ubiquitous; expressed at low levels. Not detectable in a number of hepatocarcinoma cell lines.
  • Sequence similarities

    Belongs to the PINX1 family.
    Contains 1 G-patch domain.
  • Domain

    The TID (telomerase inhibiting domain) domain is sufficient to bind TERT and inhibit its activity.
    The TBM domain mediates interaction with TERF1.
  • Cellular localization

    Nucleus. Nucleus > nucleolus. Chromosome > telomere. Chromosome > centromere > kinetochore. Localizes in nucleoli, at telomere speckles and to the outer plate of kinetochores. Localization to the kinetochore is mediated by its central region and depends on NDC80 and CENPE.
