研究背景

機能:

Glycolytic enzyme that catalyzes the transfer of a phosphoryl group from phosphoenolpyruvate (PEP) to ADP, generating ATP. Stimulates POU5F1-mediated transcriptional activation. Plays a general role in caspase independent cell death of tumor cells. The ratio between the highly active tetrameric form and nearly inactive dimeric form determines whether glucose carbons are channeled to biosynthetic processes or used for glycolytic ATP production. The transition between the 2 forms contributes to the control of glycolysis and is important for tumor cell proliferation and survival. Promotes in a STAT1-dependent manner, the expression of the immune checkpoint protein CD274 in ARNTL/BMAL1-deficient macrophages (By similarity).

PTMs:

ISGylated.

Under hypoxia, hydroxylated by EGLN3.

Acetylation at Lys-305 is stimulated by high glucose concentration, it decreases enzyme activity and promotes its lysosomal-dependent degradation via chaperone-mediated autophagy.

FGFR1-dependent tyrosine phosphorylation is reduced by interaction with TRIM35.

細胞の位置付け:

Cytoplasm. Nucleus.
Note: Translocates to the nucleus in response to different apoptotic stimuli. Nuclear translocation is sufficient to induce cell death that is caspase independent, isoform-specific and independent of its enzymatic activity.

Fig. 6 The relationship between PTP1B and AMPK. a PTP1B overexpression resulted in decreased p-AMPK (alpha). b, c The negative correlation between PTP1B and p-AMPKα was showed in pancreatic cancer patient tissue samples (p < 0.001, p value was obtained by a Pearson χ2 test; scale bar, 200 μm and 50 μm). d PTP1B inhibition either by shRNAs or by LXQ46 increased the phosphorylation of PKM2. e, f The inactivated PKM2 resulted in increased phosphorylation of AMPKα and decreased the phosphorylation of PRAS40, causing the inhibition of mTOC1 activity. g PTP1B inhibition caused AMPK activation and decreased p-p70S6K in vivo (scale bar, 200 and 50 μm).
