RT   neuroblastomas.";
RL   PLoS Genet. 10:E1003996-E1003996(2014).
CC   -!- FUNCTION: Regulates stability of MYCN in neuroblastoma cells by
CC       inhibiting GSK3B-mediated MYCN phosphorylation. Inhibits GSK3B activity
CC       by promoting its phosphorylation at 'Ser-9' (PubMed:24391509).
CC       {ECO:0000269|PubMed:24391509}.
CC   -!- SUBUNIT: Interacts with MYCN and GSK3B. {ECO:0000269|PubMed:24391509}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:24391509}. Nucleus
CC       {ECO:0000269|PubMed:24391509}.
CC   -!- TISSUE SPECIFICITY: Expressed in the neuronal cells of the cerebrum and
CC       cerebellum, spermatocytes of the testis, pancreatic cells and also the
CC       heart. Expressed in both primary and metastatic neuroblastomas and in
CC       thyroid tumors (at protein level). Expression is associated with poor
CC       prognosis in neuroblastoma. Expressed in the fetal brain, lung, liver
CC       and kidney at varying low levels. {ECO:0000269|PubMed:1419902,
CC       ECO:0000269|PubMed:24391509}.
CC   -!- DEVELOPMENTAL STAGE: Expressed during fetal development, as well as in
CC       tumor cell lines containing amplified MYCN loci, where it is expressed
CC       at very high levels.
