MYM-type zinc fingers were identified in MYM family proteins [1]. Human protein Swiss:Q14202 is involved in a chromosomal translocation and may be responsible for X-linked retardation in XQ13.1 [2]. Swiss:Q9UBW7 is also involved in disease. In myeloproliferative disorders it is fused to FGF receptor 1 [3]; in atypical myeloproliferative disorders it is rearranged [4]. Members of the family generally are involved in development. This Zn-finger domain functions as a transcriptional trans-activator of late vaccinia viral genes, and orthologues are also found in all nucleocytoplasmic large DNA viruses, NCLDV. This domain is also found fused to the C termini of recombinases from certain prokaryotic transposons [5].
