This domain is found at the N terminus of SMC proteins. The SMC (structural maintenance of chromosomes) superfamily proteins have ATP-binding domains at the N- and C-termini, and two extended coiled-coil domains separated by a hinge in the middle. The eukaryotic SMC proteins form two kind of heterodimers: the SMC1/SMC3 and the SMC2/SMC4 types. These heterodimers constitute an essential part of higher order complexes, which are involved in chromatin and DNA dynamics [1]. This family also includes the RecF and RecN proteins that are involved in DNA metabolism and recombination.	Domain

The MAGE (melanoma antigen-encoding gene) family are expressed in a wide variety of tumours but not in normal cells, with the exception of the male germ cells, placenta, and, possibly, cells of the developing embryo. The cellular function of this family is unknown. This family also contains the yeast protein, Nse3. The Nse3 protein is part of the Smc5-6 complex [2-3]. Nse3 has been demonstrated to be important for meiosis[3].	Domain
G [auth H]	PF08743	Nse4 C-terminal (Nse4_C)	Nse4 C-terminal	Nse4 is the kleisin component of the Smc5/6 DNA repair complex. It bridges the heads of Smc5 and Smc6 [1,2,3,4]. This is the C-terminal domain of Nse4 that interacts with the head domain of Smc5 [4].	Domain
