Telomeric repeat binding factor

TRF1, Telomeric Repeat Binding Protein 1, PIN2, hpr1
This gene encodes a telomere specific protein which is a component of the telomere nucleoprotein complex. This protein is present at telomeres throughout the cell cycle and functions as an inhibitor of telomerase, acting in cis to limit the elongation of individual chromosome ends. The protein structure contains a C-terminal Myb motif, a dimerization domain near its N-terminus and an acidic N-terminus. Two transcripts of this gene are alternatively spliced products.

Moreover, the insufficient level of these proteins correlated with an increase of γ-H2AX foci in the affected telomeres and resulted in telomere associations involving TRF1 and telomere detachment in later prophase-I stages.

Kibenge et al., Charlottetown, Canada. In Virol J, Dec 2015
To date, all of the ISAV isolates from the clinical disease, ISA, have had deletions in the highly polymorphic region (HPR) on ISAV segment 6 (ISAV-HPRΔ) relative to ISAV-HPR0, named numerically from ISAV-HPR1 to over ISAV-HPR30.
Cellular events of strigolactone signalling and their crosstalk with auxin in roots.
Review
New
Koltai, Israel. In J Exp Bot, Aug 2015
Strigolactones are also involved with the response to phosphate conditions in roots, acting by both dampening auxin transport via depletion of PIN2 from the plasma membrane and inducing TIR1 transcription to increase auxin perception.
LPTS: A Novel Tumor Suppressor Gene and a Promising Drug Target for Cancer Intervention.
Review
Liu et al., Chongqing, China. In Recent Pat Anticancer Drug Discov, 2014
This review successively describes the lpts genomic assembly, transcriptional regulation and structure-activity evaluation of different LPTS isoforms; then it represents the LPTS binding partners, for example Pin2/TRF1 and MCRS2, which play important roles in decreasing telomerase activity, which benefits to reveal the anticancer mechanism; subsequently, it surveys several patents of recombinant LPTS proteins such as TAT-LPTS-LC, PinX1/C-G4S-9R-G4S-mBAFF and PinX1/C-9R-mBAF that can inhibit the growth of tumor cells.

The TRF1-binding protein TERB1 promotes chromosome movement and telomere rigidity in meiosis.

Novel anticancer strategy aimed at targeting shelterin complexes by the induction of structural changes in telomeric DNA: hitting two birds with one stone.
Review
Skladanowski et al., Gdańsk, Poland. In Curr Cancer Drug Targets, 2013
These changes would lead to a selective interference with the formation of telomeric DNA-shelterin complexes, especially involving TRF1 and TRF2 proteins, as these proteins bind double-stranded telomeric DNA in a sequence- and structure-dependent manner.
THOC5, a member of the mRNA export complex: a novel link between mRNA export machinery and signal transduction pathways in cell proliferation and differentiation.
Review
Tamura et al., Hannover, Germany. In Cell Commun Signal, 2013
