Example sentences for: nucleophosmin
How can you use “nucleophosmin” in a sentence? Here are some example sentences to help you improve your vocabulary:
An amino acid comparison of NPM3 with these other members of the nucleophosmin/nucleoplasmin family from various metazoans reveals extensive sequence identities and similarities throughout all of NPM3 except the C-terminal 16 residues (Figure 3).
Indeed, NO29, a Xenopus protein with significant similarity to NPM3, is found to associate with NO38, the Xenopus ortholog of mammalian nucleophosmin [ 43 ] .
The striking similarities in amino acid sequence and domain structure between NPM3 and its chaperone relatives, nucleophosmin and nucleoplasmin, together with abundant expression levels and nuclear localization, strongly suggests that NPM3 shares fundamental nuclear chaperone functions with these proteins.
A nucleic acid binding domain in the C-terminus of nucleophosmin is also lacking in NPM3 and nucleoplasmin, but the known functions of nucleoplasmin in nucleosome assembly and sperm decondensation suggest that this protein, and possibly NPM3, can accomplish intermolecular reactions involving nucleic acids in other ways, perhaps by associating with other proteins that have this binding activity.
We previously discovered and initially characterized a novel member of this family in the mouse, namely nucleophosmin/nucleoplasmin 3 ( Npm3 ). To identify the human ortholog of Npm3 and begin its characterization, we have cloned a human NPM3 cDNA, determined its genomic structure and relationship to other family members and show its expression in multiple tissues and subcellular localization in the nucleus.
