Description of Recombinant Human NAP1L1 Protein, N-His

Introduction to Recombinant Human NAP1L1 Protein

Recombinant Human NAP1L1 Protein, also known as nucleosome assembly protein 1-like 1, is a protein that plays a crucial role in the formation of nucleosomes, the basic structural unit of chromatin. This protein is encoded by the NAP1L1 gene and is highly conserved among different species, indicating its importance in cellular processes.

Structure of Recombinant Human NAP1L1 Protein

The human NAP1L1 protein is composed of 337 amino acids and has a molecular weight of approximately 38 kDa. It contains several functional domains, including a histone binding domain and a nucleosome assembly domain, which are essential for its activity.

The crystal structure of NAP1L1 has been determined, revealing its unique three-dimensional architecture. The protein is composed of two distinct domains connected by a flexible linker region. The N-terminal domain contains the histone binding site, while the C-terminal domain contains the nucleosome assembly site. This structure allows NAP1L1 to interact with both histones and DNA, facilitating the assembly of nucleosomes.

Activity of Recombinant Human NAP1L1 Protein

Recombinant Human NAP1L1 Protein plays a crucial role in the assembly of nucleosomes, which are the building blocks of chromatin. It has been shown to interact with both histones and DNA, facilitating the formation of stable nucleosome structures.

NAP1L1 binds to histones, specifically H2A-H2B dimers, through its histone binding domain. This interaction is essential for the recruitment of histones to the DNA, which is the first step in nucleosome formation. NAP1L1 also has a nucleosome assembly domain, which interacts with DNA and promotes the formation of nucleosome structures.

Furthermore, NAP1L1 has been shown to have a chaperone-like activity, assisting in the proper folding and assembly of histones onto DNA. This activity is crucial for maintaining the stability and integrity of nucleosomes, which are essential for gene regulation and other cellular processes.
