The precise residue numbers of the amino acid residues in chain M (snRNP Sm D1) cannot be determined because of the number of GR repeats near the C-terminus of the protein. They are numbered as residues 109-114. However, this region could actually be 97-102, or any stretch of GRGRGR between residues 97 and 114.
