Receptor Protein Tyrosine Phosphatases possess a single transmembrane domain and are localized to the plasma membrane. The Protein Tyrosine Phosphatases are defined by the active-site signature motif Cys-X5-Arg. (Adapted from FBrf0129980 and PMID:17057753).
Notes on Group
IA-2 is predicted to encode a pseudophosphatase in FBrf0227974 and is therefore omitted from this group.
