PTPRS is a member of a subfamily of receptor type PTPases that is characterized by the presence of an extracellular cell adhesion molecule-like motif and 2 intracellular phosphatase domains. The extracellular region of this protein is composed of multiple Ig-like and fibronectin type III-like domains. Studies of the similar gene in mice suggested that this PTP may be involved in cell-cell interaction, primary axonogenesis, and axon guidance during embryogenesis.
Human PTPRS (GenBank Accession No. BC104812), a.a. 883-end, with N-terminal GST-tag, MW= 98 kDa, expressed in an E. coli expression system.
