Previous GeneCards Identifiers for TXNIP Gene
This gene encodes a thioredoxin-binding protein that is a member of the alpha arrestin protein family. Thioredoxin is a thiol-oxidoreductase that is a major regulator of cellular redox signaling which protects cells from oxidative stress. This protein inhibits the antioxidative function of thioredoxin resulting in the accumulation of reactive oxygen species and cellular stress. This protein also functions as a regulator of cellular metabolism and of endoplasmic reticulum (ER) stress. This protein may also function as a tumor suppressor. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Sep 2015]
GeneCards Summary for TXNIP Gene
TXNIP (Thioredoxin Interacting Protein) is a Protein Coding gene. Diseases associated with TXNIP include hyperglycemia. Among its related pathways are Immune System and Nucleotide-binding domain, leucine rich repeat containing receptor (NLR) signaling pathways. GO annotations related to this gene include ubiquitin protein ligase binding and enzyme inhibitor activity. An important paralog of this gene is ARRDC3.
UniProtKB/Swiss-Prot for TXNIP Gene
May act as an oxidative stress mediator by inhibiting thioredoxin activity or by limiting its bioavailability. Interacts with COPS5 and restores COPS5-induced suppression of CDKN1B stability, blocking the COPS5-mediated translocation of CDKN1B from the nucleus to the cytoplasm. Functions as a transcriptional repressor, possibly by acting as a bridge molecule between transcription factors and corepressor complexes, and over-expression will induce G0/G1 cell cycle arrest. Required for the maturation of natural killer cells. Acts as a suppressor of tumor cell growth. Inhibits the proteasomal degradation of DDIT4, and thereby contributes to the inhibition of the mammalian target of rapamycin complex 1 (mTORC1).
