Immunocytochemistry/Immunofluorescence: PTP1B/PTPN1 Antibody (001) [NBP2-89399] - Staining of human PTPN1 in A549 and Hela cells. Cells were fixed with 4% PFA, blocked with 10% serum, and incubated with NBP2-89399 (1:60) at 4c overnight. Then A549 cells were stained with the Alexa Fluor 549-conjugated Goat Anti-rabbit IgG secondary antibody (figure A, captured by fluorescence microscope); Hela cells were stained with the Alexa Fluor(R) 488-conjugated Goat Anti-rabbit IgG secondary antibody (figure B, captured by laser confocal scanning microscope), countstained with DAPI (blue). Positive staining was localized to cytoplasm.

Background: PTP1B

The non-transmembrane protein tyrosine phosphatase, PTP1B, comprises 435 amino acids, of which the C-terminal 114 residues have been implicated in controlling both localization and function of this enzyme. Increased phosphorylation of PTP1B is seen to accompany the transition from G2 to M phase of the cell cycle. Immunofluorescence experiments indicate that PTP-1B is localized predominantly in the endoplasmic reticulum (ER). Subcellular fractionation is consistent with this localization and establishes that PTP-1B is tightly associated with microsomal membranes, with its phosphatase domain oriented towards the cytoplasm. The finding of a tyrosine phosphatase on the ER suggests new possibilities for cellular events controlled by tyrosine phosphorylation (2). It has also been shown that PTP1B is a novel substrate for Akt and that phosphorylation of PTP1B by Akt at Ser(50) may negatively modulate its phosphatase activity creating a positive feedback mechanism for insulin signaling (3).
