Nucleolin (NCL, also called Protein C23) is a major phosphoprotein present in nucleolus of growing eukaryotic cells which is implicated in the synthesis as well as maturation of ribosomes. Localized mainly to nucleolus, NCL may also be found in cytoplasmic mRNP granules containing untranslated mRNAs (mRNP granule complex contains - NCL, ACTB, ACTN4, DHX9, ERG, HNRNPA1, HNRNPA2B1, HNRNPAB, HNRNPD, HNRNPL, HNRNPR, HNRNPU, HSPA1, HSPA8, IGF2BP1, ILF2, ILF3, NCBP1, PABPC1, PABPC4, PABPN1, RPLP0, RPS3, RPS3A, RPS4X, RPS8, RPS9, SYNCRIP, TROVE2, YBX1 and untranslated mRNAs). NCL interacts with APTX, NSUN2, TERT, ERBB4, GZF1, GZF1, NVL and C1QBP, and is a part of SWAP complex (NPM1, NCL, PARP1 and SWAP70) as well as another complex containing NCL, HTATSF1/Tat-SF1, CDK9 and CCNT1, RNA polymerase II, SUPT5H. NCL may be found associated with intranucleolar chromatin and pre-ribosomal particles where it induces chromatin de-condensation via binding to histone H1 and play a key role in pre-rRNA transcription as well as ribosome assembly. NCL has also been suggested to implicate in the process of transcriptional elongation and it binds RNA oligonucleotides with 5'-UUAGGG-3' repeats more tightly than telomeric single-stranded DNA 5'-TTAGGG-3' repeats. Besides being essential to rRNA processing in nucleolus, NCL has several other functions such as transcription regulation, modulation of mRNA stability and DNA replication and recombination.
