Molecular aspects of Schistosoma mansoni female maturation
Memorias do Instituto Oswaldo Cruz, 1995 Incubation of total protein extracts of Schistosoma mansoni with 3H 17-beta-estradiol and 20-hydroxyecdysone, revealed steroid binding proteins in both, male and female worms.

Single-molecular quantification of flowering control proteins within nuclear condensates in live whole Arabidopsis root [PDF]
Methods Mol Biol . 2022;2476:311-328, 2021 Here we describe the coupled standardisation of two complementary fluorescence imaging techniques and apply it to liquid-liquid phase separated condensates formed from an EGFP fluorescent reporter of Flowering Control Locus A (FCA), a protein that associates with chromosomal DNA in plants during epigenetic regulation of the flowering process. First, we

Reconstitution of nuclear protein export in isolated nuclear envelopes [PDF]
The Journal of Cell Biology, 2002 Signal-dependent nuclear protein export was studied in perforated nuclei and isolated nuclear envelopes of Xenopus oocytes by optical single transporter recording. Manually isolated and purified oocyte nuclei were attached to isoporous filters and made permeable for macromolecules by perforation.

Heat shock protein 60 in vascular biology [PDF]
Scripta MedicaThe response of heat shock proteins (HSPs) to stress-induced stimuli is now well documented and understood. Specific HSPs like HSP70 play an important role in vascular diseases like atherosclerosis and hypertension. However, the involvement of other HSPs

Explicit models of motions to understand protein side-chain dynamics [PDF]
, 2022 Nuclear magnetic relaxation is widely used to probe protein dynamics. For decades, most analyses of relaxation in proteins have relied successfully on the model-free approach, forgoing mechanistic descriptions of motions. Model-free types of correlation functions cannot describe a large carbon-13 relaxation dataset in protein sidechains.

Characterization of nuclear polyadenylated RNA-binding proteins in Saccharomyces cerevisiae. [PDF]
, 1994 To study the functions of heterogeneous nuclear ribonucleoproteins (hnRNPs), we have characterized nuclear polyadenylated RNA-binding (Nab) proteins from Saccharomyces cerevisiae.

Improvement of the solubilization of proteins in two-dimensional electrophoresis with immobilized pH gradients [PDF]
Electrophoresis 18 (31/03/1997) 307-16, 2006 Membrane and nuclear proteins of poor solubility have been separated by high resolution two-dimensional (2-D) gel electrophoresis. Isoelectric focusing with immobilized pH gradients leads to severe quantitative losses of proteins in the resulting 2-D map, although the resolution is usually high.

Rapid protein assignments and structures from raw NMR spectra with the deep learning technique ARTINA [PDF]
, 2022 Nuclear Magnetic Resonance (NMR) spectroscopy is one of the major techniques in structural biology with over 11,800 protein structures deposited in the Protein Data Bank. NMR can elucidate structures and dynamics of small and medium size proteins in solution, living cells, and solids, but has been limited by the tedious data analysis process.

Energy- and temperature-dependent transport of integral proteins to the inner nuclear membrane via the nuclear pore [PDF]
, 2004 Resident integral proteins of the inner nuclear membrane (INM) are synthesized as membrane-integrated proteins on the peripheral endoplasmic reticulum (ER) and are transported to the INM throughout interphase using an unknown trafficking mechanism.

Evidence for ubiquitin-regulated nuclear and subnuclear trafficking among Paramyxovirinae matrix proteins. [PDF]
PLoS Pathogens, 2015 The paramyxovirus matrix (M) protein is a molecular scaffold required for viral morphogenesis and budding at the plasma membrane. Transient nuclear residence of some M proteins hints at non-structural roles.
