High impact information on REG2

• Together, our data are consistent with a model in which Reg1p and Reg2p control the activity of PP1 toward substrates that are phosphorylated by the Snf1p kinase [1].
• We have isolated a previously uncharacterized gene, REG2, on the basis of its ability to interact with Glc7p in the two-hybrid system [1].
• These results indicate that REG1 has a unique role in the glucose repression pathway but acts together with REG2 to regulate some as yet uncharacterized function important for growth [1].
• Mutants with a deletion of reg1 display a mild slow-growth defect, while reg2 mutants exhibit a wild-type phenotype [1].
• Protein phosphatase type-1 regulatory subunits Reg1p and Reg2p act as signal transducers in the glucose-induced inactivation of maltose permease in Saccharomyces cerevisiae [2].

Biological context of REG2

• Overexpression of Reg2p in a reg1delta strain suppresses the effect on maltose permease proteolysis and partially restores the inactivation of maltose transport activity, but does not affect the insensitivity of MAL gene expression to repression by glucose observed in this strain [2].

Associations of REG2 with chemical compounds

• Loss of Reg2p modestly reduces the rates of both glucose-induced proteolysis of maltose permease and inactivation of maltose transport activity [2].

Other interactions of REG2

• The REG2 gene of Saccharomyces cerevisiae encodes a type 1 protein phosphatase-binding protein that functions with Reg1p and the Snf1 protein kinase to regulate growth [1].
