Catalyzes the specific dephosphorylation of phosphoarginine residues in proteins. Probably counteracts the protein arginine kinase McsB in vivo. Exhibits almost no activity against pTyr peptides. Protein arginine phosphorylation has a physiologically important role and is involved in the regulation of many critical cellular processes, such as protein homeostasis, motility, competence, and stringent and stress responses, by regulating gene expression and protein activity.

Belongs to the low molecular weight phosphotyrosine protein phosphatase family.
