Pathway:
  • | part of a conserved kinase cascade including Ste7p and Ste11p
  • | default mating pathway requires Axl1p, Fus1p, Fus2p, Fus3p, Pea2p, Rvs161p, Bni1p and Spa2p
  • | these proteins are also required for efficient cell fusion during chemotropic mating
InterPro:
Localization:  FUS3 localization details
  • cytoplasm
  • nucleus
  • mitochondria
Remarks:
  • cannot be substituted by Kss1p for G1 arrest function
  • inactivation of catalytic site leads to hyperphosphorylation
  • hyperphosphorylation of fus3gf is independent of Ste7p
  • FUS3 dephosphorylated by Msg5p
  • CLN2 overexpression represses Fus3p kinase activity, independently of Msg5p
    Phenotypes:  Disruption: FUS3 details
    • viable
    ___
    • gain of function mutant fus3gf requires Ste7p and Ste11p for activity
    • gain of function mutant fus3gf has higher autophosphorylation on tyrosine and increased sensitivity to upstream signals
    • null mutation increases the transposition of genomic Ty1 elements 18- to 56-fold, but has little effect on the transposition of related Ty2 elements | PUBMED
    Suppression:
    • suppresses growth defect of gpa1 mutation
