HOMOLOGY

FAMILY	protein-tyrosine phosphatase family, receptor class 2A subfamily
	Leukocyte antigen related (LAR) family receptor
	LAR-RPTP subfamily

CATEGORY

receptor membrane

SUBCELLULAR LOCALIZATION	extracellular
	plasma membrane
	intracellular
	intracellular,cytoplasm,cytosolic
	intracellular,nucleus

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
	PTPRS represents an evolutionarily conserved Plasmacytoid dendritic cells (pDCs)-specific inhibitory receptor, and is required to prevent spontaneous IFN production and immune-mediated intestinal inflammation
	PTPRS, PTPRD, PTPRF participate in several brain functions

INTERACTION

DNA

RNA

small molecule

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
	NME2 interacts with PTPRS, and NME2 associates with PTPRS to elicit neurite outgrowth inhibition in response to chondroitin sulfate proteoglycans (CSPGs)
	PTPRS regulate RAS pathway activation through ERK, and modulates ERK phosphorylation and subsequent translocation to the nucleus

half of the mouse embryos lacking both Ptprs and Ptprf (LAR) exhibit micrognathia (small lower jaw), cleft palate and microglossia/glossoptosis (small and deep tongue), a phenotype closely resembling Pierre-Robin
