Cloning 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 کاملCloning and characterization of a mouse cDNA encoding a cytoplasmic protein-tyrosine-phosphatase.
A mouse cDNA encoding a non-receptor-type phosphotyrosine phosphatase (PTP; EC 3.1.3.48) has been isolated. The 1570-base-pair cDNA contains a single open reading frame that predicts a 382-amino acid protein with Mr 44,640. The nucleic acid and amino acid sequences are homologous to those of a previously described human T-cell PTP [Cool, D. E., Tonks, N. K., Charbonneau, H., Walsh, K. A., Fisch...
متن کاملCloning, Expression, and Refolding of PPE17 Protein of Mycobacterium Tuberculosis as a Promising Vaccine Candidate
Background: Tuberculosis as a global health problem requires special attention in the contexts of prevention and control. Subunit vaccines are promising strategies to protect burdens of tuberculosis via increasing the BCG protection. The present study aimed to design a vaccine study by means of high-throughput expression and correct refolding of recombinant protein PPE17. Methods: We aimed to c...
متن کاملCloning, bacterial expression, purification, and characterization of the cytoplasmic domain of rat LAR, a receptor-like protein tyrosine phosphatase.
This report describes the cloning and characterization of rat leukocyte common antigen-related protein (rLAR), a receptor-like protein tyrosine phosphatase (PTPase). The recombinant cytoplasmic PTPase domain was expressed at high levels in bacteria and purified to homogeneity. Kinetic properties of the PTPase were examined along with potential modulators of PTPase activity. Several sulfhydryl-d...
