Product Specifications
Immunogen
This TRF-2 Antibody (4A794.15) was developed against Baculovirus expressed whole length TRF2 protein, used for immunizing mice and splenocytes used to generate the hybridoma clone (NP_005643).
Specificity
The TRF2 antibody recognizes full-length TRF2 as well as TRF2 forms lacking both the N-terminal basic domain (B) and the telobox Myb-like C-terminal DNA-binding domain (M). TRF2 forms missing the B and M domains are often referred to as mutant TRF2. Although the exact epitope recognized by the TRF2 antibody has not been mapped, the scientific literature indicates it is in the D or L domain, but not in the B or M domain.
Clonality
Monoclonal
Host
Mouse
Isotype

Background: TRF-2
Both TRF2 and TRF1 bind to telomeric double stranded 5'-TTAGGG-3' DNA repeats, then recruit RAP1, TIN2, TPP1, and POT1 for the assembly of the shelterin complex. The telomeric association of TRF2 is greatly increased in the S phase of the cell cycle (2). Loss of TRF2 leads to telomere shortening, the DNA damage response, chromosomal instability, and replicative senescence. Interestingly, the contribution of TRF2 to telomere shortening via a telomerase-independent mechanism has also been reported (3). In conjunction with the exonuclease, Apollo, TRF2 protects telomeres during replication and negatively regulates the accumulation of DNA topoisomerase (TOP1, TOP2A and TOP2B).
TRF2 has been implicated in cancer, shown to be a major oncogene in telomerase-deficient mice. A link to Werner syndrome, a premature aging disease caused by the loss of WRN, has been reported based on TRF2 recruitment of WRN for processing of telomeric DNA (4). TRF2 expression is increased during human embryonic stem cell differentiation and has been shown to interact with Repressor Element-1 Silencing Transcription Factor (REST), protecting it from proteasomal degradation (5).
