Function

TSN_HUMAN 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.^[1] ^[2] 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.^[3] ^[4]

Publication Abstract from PubMed

The structure of human translin at 2.2 A resolution is reported in space group C222(1). Translin forms a tetramer in the asymmetric unit. Although the monomer structure is almost the same as the crystal structure of murine translin in space group P2(1)2(1)2, the relative positions of the tetramers differ between the human and murine translins. This suggests that the multimerization of translin is flexible; the flexibility may be related to the binding to DNA/RNA.
