S. pombe MCM proteins and their positions in the complex

MCM protein	S. pombe gene	MCM complex component
MCM2	cdc19+/nda1+	Peripheral (forms subcomplex with core complex)
MCM3	mcm3+	Peripheral dimer
MCM4	cdc21+	Core complex
MCM5	nda4+	Peripheral dimer
MCM6	mis5+	Core complex
MCM7	mcm7+	Core complex

Designation of membership in the MCM complex is based on previous studies (Burkhart et al., 1995; Kimura et al., 1996; Schulte et al., 1996; Adachi et al., 1997; Kubota et al., 1997; Thommes et al., 1997; Sherman and Forsburg, 1998; Sherman et al., 1998).
