Description of YKR089C: Triacylglycerol lipase involved in triacylglycerol mobilization and degradation; found in lipid particles; potential Cdc28p substrate[1][2][3]



Alleles, Strains, and Phenotypes

Multiple Knockout Strains

Together with: TGL3
Phenotype(s): Loss of function (Null), Recessive, Viable

tgl3 tgl4 double mutants are unable to degrade triglycerides in lag and early log-phases of growth [1] [4]


Protein Details

Protein Function/Process

Together with: TGL3

Triglyceride lipase activity; Functional complementation of tgl4 mutants by murine ATGL, Adipose Triglyceride Lipase [1] [4]


Protein Modification

Modification(s): Phosphorylation

Identified as an efficient substrate of Clb2-Cdk1-as1 in a screen of a proteomic GST-fusion library. [3] [5]
