Among the post-translational modifications, phosphorylation is a vital regulatory mechanism of key proteins involved in specific pathways. Reverse phosphorylation has become recognized as the key process of regulation of gene expression, cellular proliferation, differentiation in Eukaryotes. The protein phosphatases can be divided into two main groups: protein tyrosine phosphatases (PTPs) and protein serine/threonine phosphatases (PPs) which remove phosphate from proteins/peptides containing phosphotyrosine (pTyr) or phosphoserine/phosphothreonine (pSer/pThr), respectively. Several of the PTPs are known to control the function of growth factor receptors, many of which are tyrosine kinases encoded by oncogenes. PTPmu participates in homophilic binding of extracellular surface of adjacent cells. PTPmu is reported to be downregulated in glioblastoma in which it regulates cell migration and growth factor-independent survival Monoclonal Anti-Protein Tyrosine Phosphatase mu recognizes PTPmu isoforms in all mammalian species.

A high protein tyrosine phosphatase (PTPase) activity is required to maintain circulating T lymphocytes in a resting phenotype, and to limit the initiation of T cell activation. We report that 15 of the currently known 24 intracellular PTPases are expressed
Glioblastoma multiforme (GBM), the most common malignant primary brain tumor, represents a significant disease burden. GBM tumor cells disperse extensively throughout the brain parenchyma, and the need for tumor-specific drug targets and pharmacologic agents to inhibit cell migration and dispersal

The receptor-type protein tyrosine phosphatase PTP mu comprises an extracellular segment containing a MAM domain, an immunoglobulin domain and four fibronectin type III repeats, a transmembrane segment, and two intracellular PTP domains. We have previously shown that PTP mu binds
The cell-surface receptor protein tyrosine phosphatase mu (PTPmu) is a homophilic cell adhesion molecule expressed in CNS neurons and glia. Glioblastomas (GBMs) are the highest grade of primary brain tumors with astrocytic similarity and are characterized by marked dispersal of
MiRNAs, a group of powerful modulator of gene expression, participate in multiple cellular processes under physiological and pathological conditions. Emerging evidence shows that Drosha, which controls the initial step in canonical miRNA biogenesis, is involved in modulating cell survival and
