Coordinates Chr X:79262..76803
Primary SGDID S000003723


Description of YJL187C: Protein kinase that regulates the G2/M transition by inhibition of Cdc28p kinase activity; localizes to the nucleus and to the daughter side of the mother-bud neck; homolog of S. pombe Wee1p; potential Cdc28p substrate[1][2][3]

Alleles, Strains, and Phenotypes

Complete Deletion

Strain Background: W303 (see detailed notes from Rodney Rothstein and Stephan Bartsch for the W303 strain used in the study)
Genotype: SH24: swe1::URA3 bar1
Phenotype(s): Loss of function (Null), Premature entry into mitosis, Viable

Despite previous reports to the contrary, swe1 mutant cells enter mitosis prematurely at a reduced bud size. [4] [5]


Point Mutation

Strain Background: BF264-15D
Phenotype(s): Dominant, stabilized

Deletion or mutation of residues between Leu320 and Tyr332 stabilizes Swe1p. [6] [7]


Interactions

Other Interactions

Other Topic: NOT Regulatory Other Interactions interaction with MET30
Despite previous reports to the contrary, Met30p is not required for Swe1p degradation [6] [7]


Other

Localization

Swe1p localization to the neck abolished by mutations in residues Leu320, Leu324, Phe327, Lys328,Leu331, or Tyr332 [6] [7]


Protein Details

Protein Modification

Modification(s): Phosphorylation

Identified as an efficient substrate of Clb2-Cdk1-as1 in a screen of a proteomic GST-fusion library. [3] [8]
