Bioorthogonal Engineering of Cellular Microenvironments Using Isonitrile Ligations
Advanced Functional Materials, EarlyView.Highly selective chemistries are required for fabrication and post‐cross–linking modification of cell‐encapsulating hydrogels used in tissue engineering applications. Isonitrile ligation reactions represent a promising class of bioorthogonal chemistries for engineering hydrogel‐based cellular microenvironments. Isonitrile‐based hydrogels are stable and

Identification of a nuclear protein matrix.
Biochemical and Biophysical Research Communications, 1974Abstract The structural framework of the rat liver nucleus has been identified and consists of a nuclear protein matrix. This matrix is 98.4% protein, 0.1% DNA, 1.2% RNA, and 0.5% phospholipid. The nuclear protein matrix is composed primarily of three acidic polypeptide fractions in the molecular weight range of 60–70,000 daltons.

Critical Reviews in Biochemistry and Molecular Biology, 1989
The nucleus, like all organelles, is composed of a unique set of proteins. This article discusses the possible mechanisms for localization of only certain proteins to the nucleus, transport of proteins across the nuclear envelope, and retention of proteins in the nuclear interior.

L'article est une revue generale concernant le transport, apres synthese cytoplasmique, des proteines nucleaires dans le noyau a travers la membrane nucleaire. Les techniques d'etude sont presentees (techniques in vivo sur cellules, in vitro sur noyaux artificiels ou noyaux naturels reconstitues, approche genetique).

Nuclear protein kinases include enzymes that transfer the gamma-phosphate of ATP to serine, threonine, lysine or histidine in proteins. Nuclear kinases with a preference for basic proteins are known as histone kinases; those preferring acidic protein substrates are casein kinases.

Nuclear export of proteins: The role of nuclear retention
Cell, 1993Proteins that shuttle between nucleus and cytoplasm are implicated in transport and signal transduction processes. Using assays based on interspecies heterokaryons and microinjection of Xenopus oocytes, we examined what structural features determine nuclear export of shuttling proteins.

Abstract The nuclear matrix of mouse liver nuclei was examined after extraction of the chromatin with high salt, deoxyribonuclease and Triton X-100. The residual nuclear matrix is composed of a nuclear pore-lamina complex, fibrillar nucleoli, and intranuclear matrix.

Proteome analysis is becoming a powerful tool of discovery-driven research, with investigations ranging from whole organisms to specific subcellular compartments. Especially for the latter, efficient and robust methods for protein purification are the prerequisite for obtaining meaningful proteomic data.

NuMA, a nuclear protein involved in mitosis and nuclear reformation [PDF]
Current Opinion in Cell Biology, 1994 NuMA, a nuclear protein that associates with the mitotic apparatus, was identified in 1980 as a high molecular weight component of the nuclear matrix with the unusual property of associating with the microtubules of the spindle apparatus during mitosis.

Phosphorylation of nuclear proteins
Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1983Many nuclear proteins are phosphorylated: they range from enzymes to several structural proteins such as histones, non-histone chromosomal proteins and the nuclear lamins. The pattern of phosphorylation varies through the cell cycle. Although histone H1 is phosphorylated during interphase its phosphorylation increases sharply during mitosis. Histone H3,
