Recombinant Human Translin (TSN)

Uniprot Id

Q15631

Target Species

Human

Target Name

TSN

Target Full Name

Translin

Target Function

DNA-binding protein that specifically recognizes consensus sequences at the breakpoint junctions in chromosomal translocations, mostly involving immunoglobulin (Ig)/T-cell receptor gene segments. Seems to recognize single-stranded DNA ends generated by staggered breaks occurring at recombination hot spots.; Exhibits both single-stranded and double-stranded endoribonuclease activity. May act as an activator of RNA-induced silencing complex (RISC) by facilitating endonucleolytic cleavage of the siRNA passenger strand.

Target Subcellular Location

Cytoplasm. Nucleus.

Target Protein Families

Translin family

Target Synonyms

BCLF 1; BCLF1; Component 3 of promoter of RISC; RCHF1; recombination hotspot associated factor; recombination hotspot binding protein; rehf 1; REHF1; TBRBP; Translin; TRSLN; TSN; TSN_HUMAN

Target Background

This gene encodes a DNA-binding protein which specifically recognizes conserved target sequences at the breakpoint junction of chromosomal translocations. Translin polypeptides form a multimeric structure that is responsible for its DNA-binding activity. Recombination-associated motifs and translin-binding sites are present at recombination hotspots and may serve as indicators of breakpoints in genes which are fused by translocations. These binding activities may play a crucial role in chromosomal translocation in lymphoid neoplasms. This protein encoded by this gene, when complexed with translin-associated protein X, also forms a Mg ion-dependent endoribonuclease that promotes RNA-induced silencing complex (RISC) activation. Alternative splicing results in multiple transcript variants.
