Expression of receptor protein-tyrosine phosphatase α mRNA and protein during mouse embryogenesis
Receptor protein-tyrosine phosphatase alpha (RPTP alpha) is a transmembrane member of the family of protein-tyrosine phosphatases (PTPs) that has been implicated in neuronal differentiation in vitro. Here we demonstrate that RPTP alpha is differentially expressed during mouse embryogenesis in a spatio-temporal manner. RPTP alpha expression was detectable in 6 days post coitum (dpc) embryos, but...
متن کاملconstruction and stable expression of a truncated human receptor tyrosine kinase ror1 (ror1-ecd)
expression of receptor tyrosine kinase ror1 in a wide variety of cancers has emerged as a new era focusing on targeting this receptor in cancer therapy. our preliminary re-sults indicate the presence of a truncated transcript of ror1 in tumor cells. the trun-cated ror1 encompasses extracellular and transmembrane domains, lacking catalytic kinase domain (ror1-ecd). as enzyme activity is highly d...
متن کاملCloning and expression of a yeast protein tyrosine phosphatase.
To study the regulation of tyrosine phosphorylation/dephosphorylation in Saccharomyces cerevisiae, a protein tyrosine phosphatase (PTPase) was cloned by the polymerase chain reaction (PCR). Conserved amino acid sequences within the mammalian PTPases were used to design primers which generated a yeast PCR fragment. The sequence of the PCR fragment encoded a protein with homology to the mammalian...
متن کاملCloning and expression of a protein-tyrosine-phosphatase.
A rat brain cDNA library was screened by using a mixture of oligonucleotides whose sequences were deduced from the amino acid sequence of a human placental protein-tyrosine-phosphatase (PTPase; EC 3.1.3.48) reported by Charbonneau et al. [Charbonneau, H., Tonks, N. K., Walsh, K. A. & Fischer, E. H. (1988) Proc. Natl. Acad. Sci. USA 85, 7182-7186]. The isolated clones encode a PTPase of 432 amin...
متن کاملCytokinetic failure and asynchronous nuclear division in BHK cells overexpressing a truncated protein-tyrosine-phosphatase.
Previous work has shown that a T-cell protein-tyrosine-phosphatase truncated in its carboxyl-terminal domain (delta C11.PTP) has full enzymatic activity but no longer localizes in the particulate fraction of the cell. Two baby hamster kidney (BHK) cell lines overexpressing the truncated protein are markedly multinucleate, a state likely caused by a failure in cytokinesis. Nuclei within syncytia...
