comments
This enzyme is composed of the N-terminal extracellular region, the transmembrane region, and the C-terminal cytoplasmic region. The C-terminal region contains two protein tyrosine phosphatase domains. Whilst the structures of the catalytic domains have been determined, the remainder has not been determined yet. However, according to the literature [4], homology search suggested that the N-terminal extracellular region seems to be composed of three immunoglobulin-like domains and eight fibronectin type III domains.
According to the literature [8], the second phosphatase domain has no catalytic activity, whereas the first domain retains the activily. Considering the active site residues and mutational analysis, the loss of catalytic activity is due to two residues, Leu1644 and Glu1779. When these residues are mutated into Tyr and Asp, respectively, the activity was restored (see [8]). The corresponding tyrosine may interact with phosphorylated tyrosine (see [8]).
According to the literature [8], in the first phosphatase domain, Cys1522 acts as a nucleophile, which will make an attack on an incoming phosphopeptide, whilst Asp1490 acts as a general acid.
Moreover, the catalytic domain is homologous to other phosphatase enzyme domains (S00458, D00154 in EzCatDB). These domains has Ser or Thr next to the catalytic Arg, and it acts as a modulator interacting with catalytic Cys. As this enzyme also has got the residue at the position, it may play the same role as the counterparts.
