产品介绍 :   Could participate in the response to proapoptotic stimuli and promotes cellular growth in a way that helps the tissue counteract diverse injuries. May contribute to the metastatic phenotype.Tissue specificity: Highly expressed in pancreas.

Function:

Chromatin-binding protein that converts stress signals into a program of gene expression that empowers cells with resistance to the stress induced by a change in their microenvironment. Interacts with MSL1 and inhibits its activity on histone H4 'Lys-16' acetylation (H4K16ac). Binds the RELB promoter and activates its transcription, leading to the transactivation of IER3. The NUPR1/RELB/IER3 survival pathway may provide pancreatic ductal adenocarcinoma with remarkable resistance to cell stress, such as starvation or gemcitabine treatment. In breast cancer cells, NUPR1 overexpression leads to the activation of PI3K/AKT signaling pathway, CDKN1A/p21 phosphorylation and relocalization from the nucleus to the cytoplasm, leading to resistance to chemotherapeutic agents, such as doxorubicin.

Subunit:

Monomer. Directly interacts with MSL1 and binds MORF4L1, two components of histone acetyltransferase complex; the interaction with MORF4L1 may be mediated by MSL1.

Subcellular Location:

Nucleus.

Tissue Specificity:

Widely expressed, with high levels in liver, pancreas, prostate, ovary, colon, thyroid, spinal cord, trachea and adrenal gland, moderate levels in heart, placenta, lung, skeletal muscle, kidney, testis, small intestine, stomach and lymph node, and low levels in brain, spleen, thymus and bone marrow. Not detected in peripheral blood leukocytes.

Post-translational modifications:

Phosphorylated in vitro by PKA and CK. Phosphorylation promotes DNA-binding activity.

Similarity:

Belongs to the NUPR family.
