SpurPTP-sf4 is a receptor tyrosine phosphatase subfamily first seen in the sea urchin Strongylocentrotus purpuratus.

===Evolution===
SpurPTP-sf3 has 3 members, all found in the sea urchin, S. purpuratus. 

===Domain Structure ===
All members are receptor PTPs, with an array of extracellular FN3 repeats, and intracellular twin PTP phosphatase domains, that are similar in sequence to both PTPRK and PTPRD subfamilies.

===Functions===
SpurPTP-sf4 is known only from sequence databases and has no known function.
