MRSfinder is a program to find the Matrix Attachment Region (MAR) Recognition Signature in DNA sequence. The Matrix Attachment Region (MAR) Recognition Signature (MRS), defined by van Drunen et al. (Nucleic Acids Research 1999, 27:2924-30), has been proposed as a motif characteristic of MAR. The signature is composed of two motifs (AATAAYAA and AWWRTAANNWWGNNNC (one mis-match allowed)) which lie with 200bp of each other, on either strand of the DNA duplex. MRSfinder.pl searches a user defined FASTA sequence file for all instances of the MRS and reports their positions.
