Entrez Gene Number
Entrez Gene SummaryThe protein encoded by this gene is the founding member of the protein tyrosine phosphatase (PTP) family, which was isolated and identified based on its enzymatic activity and amino acid sequence. PTPs catalyze the hydrolysis of the phosphate monoesters specifically on tyrosine residues. Members of the PTP family share a highly conserved catalytic motif, which is essential for the catalytic activity. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation. This PTP has been shown to act as a negative regulator of insulin signaling by dephosphorylating the phosphotryosine residues of insulin receptor kinase. This PTP was also reported to dephosphorylate epidermal growth factor receptor kinase, as well as JAK2 and TYK2 kinases, which implicated the role of this PTP in cell growth control, and cell response to interferon stimulation.

  • PTP1B
UniProt Number
UniProt SummaryFUNCTION: SwissProt: P18031 # May play an important role in CKII- and p60c-src-induced signal transduction cascades (By similarity).
SIZE: 435 amino acids; 49967 Da
SUBCELLULAR LOCATION: Endoplasmic reticulum membrane; Peripheral membrane protein; Cytoplasmic side.
PTM: Oxidized on Cys-215; the Cys-SOH formed in response to redox signaling reacts with the alpha-amido of the following residue to form a 4-amino-3-isothiazolidinone serine cross-link, triggering a conformational change that inhibits substrate binding and activity. The active site can be restored by reduction.
SIMILARITY: SwissProt: P18031 ## Belongs to the protein-tyrosine phosphatase family. Non-receptor class 1 subfamily. & Contains 1 tyrosine-protein phosphatase domain.

FAQ

QuestionAnswer
I still have material left to run more assays, but I need another plate. Where can I find a comparable plate?To get a comparable plate, you can purchase a Costar Brand 96-Well Half Area Plate (for Tissue Culture Section).
