Protein
Nucleoplasmin
Gene
N/A
Organism
Xenopus laevis (African clawed frog)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Core histones chaperone involved in chromatin reprogramming, specially during fertilization and early embryonic development. Nucleoplasmin is an acidic protein which is able to assemble nucleosomes by binding histones and transferring them to DNA.

Temperature dependencei

Thermostable.

Post-translational modificationi

Activated by phosphorylation of multiple serine/threonine residues, along both core and tail domains. The level of phosphorylation gradually increases during egg maturation, reaching an average of 7-10 phosphates per monomer, so that at the time of fertilization the activity of the protein is maximum.
Methylated by prmt5, yielding both monomethylated and symmetrically dimethylated Arg-192.1 Publication

Keywords - PTMi

Acetylation, Methylation, Phosphoprotein

Interactioni

Subunit structurei

Homopentamer, when bound to H2A-H2B dimers only. Homodecamer of two stacked pentamers, when bound to H2A-H2B dimers and H3-H4 tetramers simultaneously. Interacts with the heterotetramer formed by wdr77 and prmt5.3 Publications
