NCIt definition : Human PTPRJ wild-type allele is located in the vicinity of 11p11.2 and is approximately
188 kb in length. This allele, which encodes receptor-type tyrosine-protein phosphatase
eta protein, is involved in the dephosphorylation of protein-tyrosine phosphates.
Defects in the PTPRJ gene are associated with several types of cancer such as breast,
colon and lung cancers.;
