title: Identification of DNA binding specificity for TLS.
abstract: TLS (Translocated in liposarcoma) has been characterized as a rearranged gene in chromosomal translocations specific of human myxoid liposarcoma. The various cellular functions of TLS participating either in transcription or splicing processes are thought the involvement of an interaction of TLS with DNA and/or RNA. To investigate insight into DNA-TLS interaction, we performed Electrophoretic mobility shift assay of TLS with G-quadruplex DNA. It revealed that TLS especially bound to single stranded human telomeric DNA in the presence of potassium ion while it was not able to bind double stranded human telomeric DNA and single stranded human telomeric DNA in the presence of sodium ion.
