CC   -!- FUNCTION: DNA-binding protein that specifically recognizes consensus
CC       sequences at the breakpoint junctions in chromosomal translocations,
CC       mostly involving immunoglobulin (Ig)/T-cell receptor gene segments.
CC       Seems to recognize single-stranded DNA ends generated by staggered
CC       breaks occurring at recombination hot spots (By similarity).
CC       {ECO:0000250}.
CC   -!- FUNCTION: Exhibits both single-stranded and double-stranded
CC       endoribonuclease activity. May act as an activator of RNA-induced
CC       silencing complex (RISC) by facilitating endonucleolytic cleavage of
CC       the siRNA passenger strand (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Ring-shaped heterooctamer of six TSN and two TSNAX subunits,
CC       DNA/RNA binding occurs inside the ring. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Nucleus {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the translin family. {ECO:0000305}.
