The family can be separated into three general categories, which are distinguished on the basis of substrate specificity. The first and largest category, termed protein tyrosine phosphatases or PTPs, includes transmembrane proteins, membrane associated proteins and proteins that localize to nuclei. Transmembrane PTPs are involved in homophilic binding and facilitate cell-cell communication. Membrane associated PTPs include the following proteins SH-PTP1 (PTP1C, HCP, SHP), SH-PTP2 (Syp, PTP1D), PTP-H1 and PTP1B. Fap-1 (also designated PTP-BAS) contains an ezrin-like membrane binding domain and through its association with FAS presumably regulates FAS signaling. PTPs, such as KAP (also designated Cdi1), function to regulate the activity of proteins in the nuclei of cells. The second category of protein phosphatases dephosphorylate proteins on phosphoserine and phosphothreonine residues, whereas the third category of protein phosphatases exhibit dual specificities and can dephosphorylate proteins on phosphotyrosine and phosphoserine\/phosphothreonine residues.\u003c\/p\u003e\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDecision-relevant for researchers studying Ptp1C.\u003c\/li\u003e\n\u003cli\u003eAdenovirus-mediated delivery is well-established in primary cells, organoids, and small-animal models.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePathway activation studies in cell lines and primary cells.\u003c\/li\u003e\n\u003cli\u003eGain-of-function phenotyping in disease-relevant cell models.\u003c\/li\u003e\n\u003cli\u003eRescue experiments paired with shRNA knockdown of the same target.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eAdenoviral delivery is episomal and non-integrating; expression dilutes with cell division and typically lasts 1–2 weeks in dividing cells (longer in non-dividing cells such as hepatocytes, neurons, and cardiomyocytes).\u003c\/li\u003e\n\u003cli\u003ePre-existing anti-Ad5 neutralizing antibodies are common in human and primate hosts and can reduce in vivo transduction; this is less relevant in inbred laboratory mouse strains.\u003c\/li\u003e\n\u003cli\u003eMOI optimization is essential — over-dosing can cause cytopathic effects; under-dosing yields incomplete transduction.
