Western blotting using anti-H2ac, anti-TRF2, and anti-POT1 with or without H2ac, TRF2, and POT1 proteins (OriGene TP316275) as competitors. Tubulin served internal controls. Figure cited from PLoS ONE, PMID: 27228173

• 

  Purified recombinant HA-H2ac interacted directly with purified recombinant MYC-POT1 (OriGene TP316275), as analyzed by a pulldown assay and Western blot. HA-H2acS16A served as a negative control. Figure cited from PLoS ONE, PMID: 27228173

• 

  Coomassie blue staining of purified POT1 protein (Cat# TP316275). The protein was produced from HEK293T cells transfected with POT1 cDNA clone (Cat# RC216275) using MegaTran 2.0 (Cat# TT210002).

• Summary: 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.
