a type 2 non-receptor phospho-tyrosine-protein phosphatase (PTP). Two alternatively spliced isoforms are differenyially expressed. Isoform A is a major PTP expressed in human tissues, while isoform B is expressed mainly in T-cells and in placenta. Note: This description may include information from UniProtKB.
Protein type: EC 188.8.131.52; Protein phosphatase, tyrosine (non-receptor); Motility/polarity/chemotaxis
SS: The number of records in which this modification site was determined using site-specific methods. SS methods include amino acid sequencing, site-directed mutagenesis, modification site-specific antibodies, specific MS strategies, etc.
