Alleles, Strains, and Phenotypes
Multiple Knockout Strains
Strain Background: Sigma1278b (Sigma 2000 series)
Genotype: MCY4716
Together with: NRG2, SIP1, GAL83, SIP2
Phenotype(s): Loss of function (Null)
Deletion of nrg1 partially suppresses gal83's defect in invasive growth, plastic adherance, and STA2-lacZ expression. [5] [6]
Strain Background: Sigma1278b (Sigma 2000 series)
Genotype: MCY4712
Together with: NRG2, SIP1, GAL83, SIP2
Phenotype(s): Loss of function (Null)
Deletion of nrg1 and nrg2 suppresses gal83's defect in invasive growth, plastic adherance, and STA2-lacZ expression, better than deletion of either nrg alone. [5] [6]
Strain Background: Sigma1278b (Sigma 2000 series)
Genotype: MCY4716
Together with: NRG2, SIP1, GAL83, SIP2
Phenotype(s): Loss of function (Null)
Deletion of nrg1 partially suppresses gal83's defect in invasive growth, plastic adherance, and STA2-lacZ expression. [5] [6]
Strain Background: Sigma1278b (Sigma 2000 series)
Genotype: MCY4712
Together with: NRG2, SIP1, GAL83, SIP2
Phenotype(s): Loss of function (Null)
Deletion of nrg1 and nrg2 suppresses gal83's defect in invasive growth, plastic adherance, and STA2-lacZ expression, better than deletion of either nrg alone. [5] [6]
Overexpression
Phenotype(s): Dominant, Gain of function
Overexpression of VP16-Nrg1 results in partial derepression of SUC2 in glucose grown cells. [7] [8]
Interactions
Genetic
YDR043C is a suppressor of Snf1
Strain Background: Sigma 1278b
Mutation type(s): complete deletion, complete deletion
Deletion of Nrg1 partially suppresses Snf1's defect in invasive growth, FLO11 expression, and STA2 expression. [1] [8]
Other Interactions
Other Topic: functional dependence
Other Interactions interaction with Tup1
Repression by LexA-Nrg1 of a heterologous promoter containing lexA binding sites depends on Tup1. [3] [9]
Other Topic: functional dependence
Other Interactions interaction with Cyc8
Repression by LexA-Nrg1 of a heterologous promoter containing lexA binding sites depends on Cyc8/Ssn6. [3] [9]
Physical
Physical interaction with Cyc8
Nrg1 interacts with Ssn6/Cyc8 in the two-hybrid system, and in GST pull-down experiments. [3] [9]
Physical interaction with Snf1
LexA-Snf1 coimmunoprecipitates HA3-Nrg1 [7] [8]
Physical interaction with Snf1
Snf1 coimmunoprecipitates with HA3-Nrg1 [7] [8]
Regulatory
Regulatory interaction with STA1
Nrg1 binds to the promoter of STA1, where it represses transcription of this gene. [3] [9]
Two Hybrid
Two Hybrid interaction with snf1
Snf1 kinase domain interacts with Nrg1 [7] [8]
Protein Details
Nucleic Acid Binding
Nrg1 specifically binds to two regions in the upstream activation sequence of the STA1 gene, as judged by gel retardation and DNase I footprinting analyses. [3] [9]
Protein Function/Process
LexA-Nrg1 represses transcription from a heterologous promoter containing LexA binding sites. [7] [8]
Protein Localization
Nrg1 is nuclear in both YP 2% Glucose and YP 2%Glycerol/2% Ethanol [7] [8]
