Structure of RNR regulators. A gossypii Aer122c is considered to be a prototype ancestral protein containing three domains: Hug1 (putative Rnr2p-Rnr4p binding domain), Sml1 (a degron for Smlp degradation after phosphorylation by Dun1p), and R1B (Rnr1p-binding domain consisting of two subdomains, which is inactive in Dif1p). Chromosomal localization of three genes encoding RNR regulators in S. cerevisiae is also depicted in the figure. HUG1 and SML1 genes, located in tandem on chromosome XIII, are transcribed separately
