This region is found to the C-terminus of the Pfam:PF00751 [1]. DM-domain proteins with this motif are known as DMRTA proteins. The function of this region is unknown.

1: The human doublesex-related gene, DMRT2, is homologous to a gene involved in somitogenesis and encodes a potential bicistronic transcript. Ottolenghi C, Veitia R, Barbieri M, Fellous M, McElreavey K; Genomics 2000;64:179-186. PMID:10729224

2: The region on 9p associated with 46,XY sex reversal contains several transcripts expressed in the urogenital system and a novel doublesex-related domain.
