About Ptp2

  • Ptp2 contains a putative MAPK-binding sequence at residues 208-220. Metodiev et al. 2002 PMID 12029138
  • Ptp2 is nuclear. Mattison et al. 1999 PMID 10523653
  • Ptp2 is a protein tyrosine phosphatase. Wurgler-Murphy et al. 1997 PMID 9032256

About Ptp3

  • Ptp3 is cytoplasmic. Mattison et al. 1999 PMID 10523653
  • Ptp3 is a protein tyrosine phosphatase. Wurgler-Murphy et al. 1997 PMID 9032256
  • Ptp3 is found throughout the cytosol and nucleus, although it is slightly more concentrated in the cytosol. Maeder et al. 2007 PMID 17952059
  • Ptp3 levels do not significantly change in response to pheromone. Maeder et al. 2007 PMID 17952059

Reactions

MAPK/phosphatase interactions
Ste12 mediated protein synthesis
Protein dilution/synthesis due to cell growth

Species Representation

Since we are not treating the cytoplasm and nucleus as deparate compartments, we will lump Ptp2 and Ptp3 together into one species, Ptp.
