Phosphatase Classification: Fold CC1: Superfamily CC1: Family PTP: Subfamily MbrePTP-sf1

MbrePTP-sf1 is a tyrosine phosphatase subfamily first seen in choanoflagellates.


MbrePTP-sf1 is found in choanoflagellates, including Monosiga brevicollis, Monosiga ovata, and Salpingoeca rosetta. This subfamily may be related to the chordate PTPRK subfamily and several other unclassified phosphatases in invertebrates, though it only has a single PTP domain


Most members are fragments that suggest a single PTP domain, and varied other domains, including PDZ, Ankyrin, and Guanylate kinase domains


MbrePTP-sf1 is known only from sequence databases and has no known function.
