Human Gene AXIN1 (uc002cgp.2) Description and Page Index
  Description: Homo sapiens axin 1 (AXIN1), transcript variant 1, mRNA.
RefSeq Summary (NM_003502): This gene encodes a cytoplasmic protein which contains a regulation of G-protein signaling (RGS) domain and a dishevelled and axin (DIX) domain. The encoded protein interacts with adenomatosis polyposis coli, catenin beta-1, glycogen synthase kinase 3 beta, protein phosphate 2, and itself. This protein functions as a negative regulator of the wingless-type MMTV integration site family, member 1 (WNT) signaling pathway and can induce apoptosis. The crystal structure of a portion of this protein, alone and in a complex with other proteins, has been resolved. Mutations in this gene have been associated with hepatocellular carcinoma, hepatoblastomas, ovarian endometriod adenocarcinomas, and medullablastomas. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2016].

  ID: AXIN1_HUMAN
DESCRIPTION: RecName: Full=Axin-1; AltName: Full=Axis inhibition protein 1; Short=hAxin;
FUNCTION: Component of the beta-catenin destruction complex required for regulating CTNNB1 levels through phosphorylation and ubiquitination, and modulating Wnt-signaling. Controls dorsoventral patterning via two opposing effects; down-regulates CTNNB1 to inhibit the Wnt signaling pathway and ventralize embryos, but also dorsalizes embryos by activating a Wnt- independent JNK signaling pathway. In Wnt signaling, probably facilitates the phosphorylation of CTNNB1 and APC by GSK3B. Likely to function as a tumor suppressor. Facilitates the phosphorylation of TP53 by HIPK2 upon ultraviolet irradiation. Enhances TGF-beta signaling by recruiting the RNF111 E3 ubiquitin ligase and promoting the degradation of inhibitory SMAD7. Also component of the AXIN1-HIPK2-TP53 complex which controls cell growth, apoptosis and development.
SUBUNIT: Homodimer (By similarity). Component of the beta-catenin destruction complex, containing at least, CTNNB1, an axin and GSK3B, that regulates CTNNB1 protein levels through phosphorylation and ubiquitination. Interacts with CTNNB1 (via the armadillo repeats 2-7). Interacts with GSK3B; the interaction hyperphosphorylates CTNNB1 leading to its ubiquitination and destruction. Component of the AXIN1-HIPK2-TP53 complex. Interacts directly in the complex with TP53 and HIPK2. Interacts with DAXX; the interaction stimulates the interaction of DAXX with TP53, stimulates 'Ser-46' phosphorylation of TP53 and induces cell death on UV irradiation. Also binds APC, SMAD6, SMAD7 and RNF111. Interacts with DIXDC1; prevents interaction with MAP3K1. Interacts with MAP3K4. Interacts with ANKRD6 and AIDA (By similarity). Interacts with MDFI; the interaction decreases AXIN1-mediated JUN N-terminal kinase (JNK) activation. Interacts with MDFIC; the interaction inhibits beta-cateninin-mediated signaling and AXIN1- mediated JUN N-terminal kinase (JNK) activation. Interacts with LRP5 (via its phosphorylated PPPSP motifs); the interaction is stimulated by WNT1 and GSK3B and activates beta-catenin signaling. Interacts (via the C-terminal) with PPP1CA; the interaction dephosphorylates AXIN1 and regulates interaction with GSK3B. Interacts with PPP2CA; the interaction dephosphorylates AXIN1. Interacts with MACF1 (By similarity). Found in a complex composed of MACF1, APC, AXIN1, CTNNB1 and GSK3B (By similarity). Interacts with TNKS. Interacts with DAB2; the interaction is mutually exclusive with the AXIN1:PPP1CA interaction.

SUBCELLULAR LOCATION: Cytoplasm. Nucleus. Cell membrane (By similarity). Note=MACF1 is required for its translocation to cell membrane (By similarity). On UV irradiation, translocates to the nucleus and colocalizes with DAAX.
TISSUE SPECIFICITY: Ubiquitously expressed.
DOMAIN: The tankyrase-binding motif (also named TBD) is required for interaction with tankyrase TNKS and TNKS2.
PTM: Phosphorylation and dephosphorylation of AXIN1 regulates assembly and function of the beta-catenin complex. Phosphorylated by CK1 and GSK3B. Dephosphorylated by PPP1CA and PPP2CA. Phosphorylation by CK1 enhances binding of GSK3B to AXIN1.
PTM: ADP-ribosylated by tankyrase TNKS and TNKS2. Poly-ADP- ribosylated protein is recognized by RNF146, followed by ubiquitination at 'Lys-48' and subsequent activation of the Wnt signaling pathway.
PTM: Ubiquitinated by RNF146 when poly-ADP-ribosylated, leading to its degradation and subsequent activation of the Wnt signaling pathway. Sumoylation at Lys-857 and Lys-860 prevents ubiquitination and degradation. Sumoylation is required for AXIN1- mediated JNK activation. Deubiquitinated by USP34, deubiquitinated downstream of beta-catenin stabilization step: deubiquitination is important for nuclear accumulation during Wnt signaling to positively regulate beta-catenin (CTNBB1)-mediated transcription.
DISEASE: Defects in AXIN1 are involved in hepatocellular carcinoma (HCC) [MIM:114550].
DISEASE: Defects in AXIN1 are a cause of caudal duplication anomaly (CADUA) [MIM:607864]. Caudal duplication anomaly is characterized by the occurrence of duplications of different organs in the caudal region. Note=Caudal duplication anomaly is associated with hypermethylation of the AXIN1 promoter.
SIMILARITY: Contains 1 DIX domain.
SIMILARITY: Contains 1 RGS domain.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
