Nuclear pore complex (NPC) mediates the shuttle movement of macromolecules between the cytoplasm and the nucleus. NPC is located in the nuclear membrane, forming a hydrophobic channel. It enables macromolecular substances such as proteins to bind to transport receptors for transmembrane transport. This transmembrane transport through the nuclear pore complex plays an important physiological function in life activities such as cell proliferation, cell differentiation, and individual development.

Creative Proteomics provides a one-stop service for nucleolar proteomics, and conducts a comprehensive analysis of nucleolar proteomics from a holistic perspective. The main contents include: 1) Study the structural composition and dynamic changes of nuclear pore complexes; 2) Study the role of nuclear pore complexes in life activities such as embryonic development, gene transcription and translation, cell differentiation, and apoptosis; 3) Study the trans-nuclear membrane transport mode of macromolecular substances; 4) Study the regulatory mechanism of matter through the nuclear pore complex; 5) Data analysis and bioinformatics analysis.
