    basic FUNCTION
  • tyrosine phosphatase receptor, putatively involved in the development of the nervous system
  • may be involved in cell-cell interaction, primary axonogenesis, and axon guidance during embryogenesis
  • PTPRD, PTPRS regulate neuroendocrine development, axonal regeneration, and hippocampal long-term potentiation
  • PTPRD and PTPRS complement each other functionally during mammalian development, and have an essential contribution to appropriate motoneuron axon targeting during axonogenesis
  • important role in the development of the nervous system and nerve regeneration
  • modulates the actin cytoskeleton by regulating Rac GTPase activity through ARHGAP32
  • modulates Rac dependent activity through regulating a novel substrate, ARHGAP32
  • acts bimodally in sensory neuron extension, mediating chondroitin sulfate proteoglycans (CSPG)inhibition and heparan sulfate proteoglycans growth (HSPG) promotion
  • PTPRS clustering would translate into an uneven distribution of phosphatase activity on the cell surface, consistent with localization-based models for receptor action

    protein
  • interacts with PPFIA1, PPFIA2 and PPFIA3
  • receptor for inhibitory chondroitin sulfate proteoglycan
  • interaction with PPFIA4, BCAR1, TRIO
  • ARHGAP32 is a novel substrate of PTPRS and PTPRS displayed its phosphatase specificity toward ARHGAP32
  • SLITRK1, SLITRK2, SLITK3, SLITRK4, SLITRK5 and SLITRK6 appeared to interact with both PTPRD and PTPRS
