Protein Tyrosin Phosphatase, cytoplasmic region, containing catalytic domain D1 C-terminally linked to the non-catalytic domain D2. PTPmu is an Ig superfamily receptor protein-tyrosine phosphatase which promotes cell-cell adhesion in a homophilic, Ca2+-independent manner and interacts with the cadherin-catenin complex. The intracellular region of PTPμ contains three domains: the juxtamembrane (JM, aa 765-923) and two phosphatase domains (D1 and D2). Only the D1 domain is catalitically active.
