Function

[NLP_DROME] Binds to core histones and functions in the ATP-facilitated assembly of approximately regularly spaced nucleosomal arrays. May participate in parallel with other histone-binding proteins such as NAP-1.^[1] ^[2] Isoform 2 is inactive for chromatin assembly. In vitro it appears to form a high molecular mass aggregate with the core histones.^[3] ^[4]

Publication Abstract from PubMed

The nucleoplasmin-like protein from Drosophila (dNLP) functions as a chaperone for core histones and may remodel chromatin in embryos. We now report the crystal structure of a dNLP-core pentamer at 1.5 A resolution. The monomer has an eight-stranded, beta barrel topology that is similar to nucleoplasmin (Np). However, a signature beta hairpin is tucked in along the lateral surface of the dNLP-core pentamer, while it extends outward in the Np-core decamer. Drosophila NLP and Np both assemble histone octamers. This process may require each chaperone to form a decamer, which would create symmetric binding sites for the histones. Conformational differences between dNLP and Np may reflect their different oligomeric states, while a conserved, nonpolar subunit interface may allow conformational plasticity during histone binding.
