Germline variant p. Asp31His was present in all affected members in three families with familial non-medullary thyroid cancer. NOP53 is likely a low-penetrant gene implicated in FNMTC.
Title: NOP53 as A Candidate Modifier Locus for Familial Non-Medullary Thyroid Cancer.
Blocking cytoplasmic translocation of nucleolar protein NOP53 by deleting its nuclear export sequence abrogated its support of viral replication. Recombinant N3-T protein, containing NOP53 residues 330-432 and a human immunodeficiency virus-derived cell-penetrating Tat peptide, attenuated the expression of IFN-beta; and IFN-stimulated genes, as well as decreased the phosphorylation of interferon regulatory factor3.

The findings of this study suggest that disruption of PICT-1 protein expression and codon 389 polymorphism can contribute to the pathogenesis or neoplastic progression of endometrial cancer.
Title: Abnormal Expression of PICT-1 and Its Codon 389 Polymorphism Is a Risk Factor for Human Endometrial Cancer.
The study presented evidence that viral infection induced translocation of GLTSCR2 from nucleus to cytoplasm, and cytoplasmic translocation enabled GLTSCR2 to effectively attenuate IFN-beta and support viral replication; however, viral infection did not result in elevating GLTSCR2 in cells.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
