PTPRT Protein
PTPRT (Protein Tyrosine Phosphatase Receptor Type T), also known as RPTPρ, is a receptor-type protein tyrosine phosphatase that plays important roles in neuronal signaling. The PTPRT protein contains an extracellular domain involved in cell-cell interactions, a transmembrane region, and an intracellular catalytic domain with phosphatase activity. Through dephosphorylation of various substrates including cytoskeletal proteins and signaling molecules, PTPRT regulates axon guidance, dendrite morphology, and synaptic formation. Dysregulation of PTPRT phosphatase activity may contribute to synaptic dysfunction in neurodevelopmental and neurodegenerative conditions.
PTPRT is a receptor-type protein tyrosine phosphatase with an extracellular domain containing multiple fibronectin type III repeats, a transmembrane region, and intracellular catalytic domains. It regulates neuronal connectivity through dephosphorylation of various substrates.

PTPRT mutations affect synaptic development and are linked to autism. It may have tumor suppressor functions.
PTPRT agonists to enhance synaptic function are under investigation.
