The DNA topoisomerase I binding protein topors as a novel cellular target for SUMO-1 modification: characterization of domains necessary for subcellular localization and sumolation. Exp Cell Res. 2003;290:13-27 pubmed..One SUMO-1 acceptor site at lysine residue 560 could be identified within this region. However, sumolation-deficient Topors mutants showed that sumolation obviously is not required for localization to nuclear speckles. ..
- Kottwitz D, Kukhtina V, Dergousova N, Alexeev T, Utkin Y, Tsetlin V, et al. Intracellular domains of the delta-subunits of Torpedo and rat acetylcholine receptors--expression, purification, and characterization. Protein Expr Purif. 2004;38:237-47 pubmed..The results suggest that the spatial structure of the intracellular loops is dependent on environment and species, but is not changed significantly upon enzymatic phosphorylation...
- Ruehl M, Erben U, Schuppan D, Wagner C, Zeller A, Freise C, et al. The elongated first fibronectin type III domain of collagen XIV is an inducer of quiescence and differentiation in fibroblasts and preadipocytes. J Biol Chem. 2005;280:38537-43 pubmed..Based on these finding the development of small molecular analogs that modulate fibroblast cell growth and differentiation, e.g. in wound healing and fibrosis, seems feasible. ..

Photosynth Res. 2005;86:175-84 pubmed..The chlorophyll a in the lumenal layer are less well conserved between Photosystems I and II and even between CP43 and CP47 with 4 chlorophyll a in the former and 7 in the latter. ..

Proc Natl Acad Sci U S A. 2007;104:2909-14 pubmed..The results substantiate our earlier suggestion of a mechanistically novel group of membrane transporters...
- Thaa B, Herrmann A, Veit M. The polybasic region is not essential for membrane binding of the matrix protein M1 of influenza virus. Virology. 2009;383:150-5 pubmed publisher..We therefore suppose that M1 probably interacts with membranes via multiple binding sites. ..

J Mol Biol. 2000;299:655-65 pubmed publisher..Furthermore, high-affinity DNA-binding of Tth-DnaA is dependent on the presence of ATP. The Thermus DnaA/oriC interaction will be compared with oriC complex formation generated by other DnaA proteins...

The solution structure of an N-terminally truncated version of the yeast CDC24p PB1 domain shows a different beta-sheet topology. FEBS Lett. 2005;579:3534-8 pubmed..Residues which are important for the heterodimerization with BEM1p are structurally preserved. ..
