Abstract
We describe here a new class of protein tyrosine phosphatases (PTP), called “PTP-NP” (for neural and pancreatic) receptors. The sequence of an exemplary PTP-NP gene (SEQ ID No. 1) indicates it encodes a receptor type PTP (SEQ ID No. 2) with a single tyrosine phosphatase domain. Comparison of PTP-NP with the other known PTPs reveals a cysteine-conserved motif in the extracellular domain and, together with their homology in the phosphatase domain, this defines a new subclass of receptor type PTPs.
