Putative ribosomal RNA methyltransferase NOP2 is an enzyme that in humans is encoded by the NOP2 gene. [5] [6]
The protein encoded by this gene is a nucleolar antigen expressed in proliferating cells. It is not detectable in non-proliferating normal tissue but is detectable in many human tumors. [7]
Overexpression of p120 leads to malignant transformation of 3T3 cells while treatment with antisense p120 mRNA causes the transformed cells to revert to their original non-malignant phenotype. [8] The p120 protein displays a dramatic increase in expression at the G1/S transition suggesting that p120 regulates the cell cycle and nucleolar activity that is required for cell proliferation. [9]
Proliferating cell nuclear antigen (PCNA) is a DNA clamp that acts as a processivity factor for DNA polymerase δ in eukaryotic cells and is essential for replication. PCNA is a homotrimer and achieves its processivity by encircling the DNA, where it acts as a scaffold to recruit proteins involved in DNA replication, DNA repair, chromatin remodeling and epigenetics.
Antigen Kiel 67, also known as Ki-67 or MKI67, is a protein that in humans is encoded by the MKI67 gene.
Nucleophosmin (NPM), also known as nucleolar phosphoprotein B23 or numatrin, is a protein that in humans is encoded by the NPM1 gene.
Y box binding protein 1 also known as Y-box transcription factor or nuclease-sensitive element-binding protein 1 is a protein that in humans is encoded by the YBX1 gene.
Nucleolin is a protein that in humans is encoded by the NCL gene.
p120 catenin, or simply p120, also called catenin delta-1, is a protein that in humans is encoded by the CTNND1 gene.
Probable ATP-dependent RNA helicase DDX5 also known as DEAD box protein 5 or RNA helicase p68 is an enzyme that in humans is encoded by the DDX5 gene.
Receptor-type tyrosine-protein phosphatase eta is an enzyme that in humans is encoded by the PTPRJ gene.
Rho guanine nucleotide exchange factor 2 is a protein that in humans is encoded by the ARHGEF2 gene.
Guanine nucleotide-binding protein-like 3, also known as nucleostemin, is a protein that in humans is encoded by the GNL3 gene. It is found within the nucleolus that binds p53. Nucleostemin regulates the cell cycle and affects cell differentiation, decreasing in amount as this differentiation progresses. It is a marker for many stem cells and cancer cells.
Ribosome biogenesis protein BOP1 is a protein that in humans is encoded by the BOP1 gene. It is a WD40 repeat-containing nucleolar protein involved in rRNA processing, thereby controlling the cell cycle. It is required for the maturation of the 25S and 5.8S ribosomal RNAs. It may serve as an essential factor in ribosome formation that coordinates processing of the spacer regions in pre-rRNA.
Nucleolar RNA helicase 2 is an enzyme that in humans is encoded by the DDX21 gene.
Probable rRNA-processing protein EBP2 is a protein that in humans is encoded by the EBNA1BP2 gene.
Protein ajuba is a protein that in humans is encoded by the JUB gene.
DNA polymerase delta subunit 3 is an enzyme that in humans is encoded by the POLD3 gene. It is a component of the DNA polymerase delta complex.
Ribosomal oxygenase 2 is a protein that in humans is encoded by the RIOX2 gene.
Nucleoside diphosphate-linked moiety X motif 6 is a protein that in humans is encoded by the NUDT6 gene.
Nucleolar protein 8 is a protein that in humans is encoded by the NOL8 gene.
Putative methyltransferase NSUN5 is an enzyme that in humans is encoded by the NSUN5 gene.
Nucleolar and spindle associated protein 1 is a protein that in humans is encoded by the NUSAP1 gene.
