Alleles, Strains, and Phenotypes

Multiple Knockout Strains

Strain Background: Sigma1278b (Sigma2000 series)
Genotype: MCY4581
Together with: NRG2, NRG1, GAL83, SIP2
Phenotype(s): Loss of function (Null)

Deletion of SIP1 suppresses gal83's defect in invasive growth in response to glucose limitation. [4] [5]


Strain Background: Sigma1278b (Sigma2000 series)
Genotype: MCY4600
Together with: REG1, GAL83, SIP2, MUC1
Phenotype(s): Loss of function (Null)

Deletion of SIP1 in a gal83 sip2 double mutant causes an increase in invasion, suggesting Sip1 negatively regulates invasive growth. [4] [5]
