General description

Monoclonal Anti-TIN2 (mouse IgG1 isotype) is derived from the hybridoma TIN-30 produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with a synthetic peptide corresponding to a fragment of human TIN-2, conjugated to keyhole limpet hemocyanin (KLH). The six shelterin subunits are: TRF1, TRF2, and POT1 which directly recognize the TTAGGG repeats, and TIN2, Rap1 and TPP1. TIN2 (TRF-1 interacting nuclear factor 2) is recruited to the telomere through the TRF homology (TRFH) domain of TRF1 and tethers TPP1/POT1 to TRF1 and TRF2.

Application

Monoclonal Anti-TIN2 antibody produced in mouse has been used in immunoblotting.

Biochem/physiol Actions

TIN2 (TRF-1 interacting nuclear factor 2) also connects TRF1 to TRF2 and this link contributes to the stabilization of TRF2 on telomeres. In addition, TIN2 has also been found to tether the telomeres to the nuclear matrix. Interestingly, this protein has also been found to be mutated in Dyskeratosis Congenita, a multi-system disorder which in its classical form is characterized by abnormalities of the skin, nails, and mucous membranes.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

The progressive bone marrow failure syndrome dyskeratosis congenita (DC) is often caused by mutations in telomerase or the factors involved in telomerase biogenesis and trafficking. However, a subset of DC patients is heterozygous for mutations in the shelterin component TIN2.

Added by telomerase, arrays of TTAGGG repeats specify the ends of human chromosomes. A complex formed by six telomere-specific proteins associates with this sequence and protects chromosome ends. By analogy to other chromosomal protein complexes such as condensin and cohesin

Germline mutations in telomere biology genes cause dyskeratosis congenita (DC), an inherited bone marrow failure and cancer predisposition syndrome. DC is a clinically heterogeneous disorder diagnosed by the triad of dysplastic nails, abnormal skin pigmentation, and oral leukoplakia; Hoyeraal-Hreidarsson syndrome
