Product Specifications

Immunogen

PTP1B/PTPN1 synthetic peptide (coupled to carrier protein) corresponds to amino acids from the N-terminal region of human PTP1B/PTPN1. This sequence has significant homology to the conserved site in rat and mouse PTP1B/PTPN1, and has homology to TC-PTP and MPTP, but not other protein tyrosine phosphatase family members. [UniProt# P18031]

Specificity

The antibody detects a 50 kDa band corresponding to PTP1B/PTPN1 in western blots of human A431, Jurkat, HeLa, and mouse SYF cells. This reactivity can be specifically blocked using PTP1B/PTPN1 (a.a. 146-157) peptide.

Clonality

Polyclonal

Host

Rabbit

Isotype

IgG

Theoretical MW

50 kDa.
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Description

Stable for at least 1 year at -20°C.

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).
