Cancer metastasis-associated protein 1 localizes to the nucleolus and regulates pre-rRNA synthesis in cancer cells.

Metastasis-associated protein 1 (MTA1) is a critical component of the nucleosome remodeling and histone deacetylase (NuRD) complex. MTA1 has several biological functions, and it is closely associated with the malignant properties of human cancers; however, the mechanisms and subcellular localization of MTA1 in cells remain unclear. Some initial studies indicated that MTA1 was absent from the nucleolus; however, several NuRD components were recently found to be present in the nucleolus, where they regulate preribosomal RNA (pre-rRNA) transcription.

On the complexity measures of mutation hotspots in human TP53 protein.

The role of sequence complexity in 23 051 somatic missense mutations including 73 well-known mutation hotspots across 22 major cancers was studied in human TP53 proteins. A role for sequence complexity in TP53 protein mutations is suggested since (i) the mutation rate significantly increases in low amino acid pair bias complexity; (ii) probability distribution complexity increases following single point substitution mutations and strikingly increases after mutation at the mutation hotspots including six detectable hotspot mutations (R175, G245, R248, R249, R273, and R282); and (iii) the degree of increase in distribution complexity is significantly correlated with the frequency of missense mutations (r = -0.5758, P < 0.
