- Huang M, Li K, Spear B. The mouse alpha-fetoprotein promoter is repressed in HepG2 hepatoma cells by hepatocyte nuclear factor-3 (FOXA). DNA Cell Biol. 2002;21:561-9 pubmed..We propose that HNF3 represses AFP promoter activity through indirect mechanisms that modulate the binding or activity of a liver-enriched factor that interacts with the -165 region of the AFP promoter. ..
- Krishnamurthy K, Mitra R, Payton M, Verchot Lubicz J. Cell-to-cell movement of the PVX 12K, 8K, or coat proteins may depend on the host, leaf developmental stage, and the PVX 25K protein. Virology. 2002;300:269-81 pubmed..Thus plasmodesmata gating is not an essential function of these proteins for virus cell-to-cell movement. These proteins likely provide additional activities for virus cell-to-cell movement...

- Zhang F, Gonzalez A, Zhao M, Payne C, Lloyd A. A network of redundant bHLH proteins functions in all TTG1-dependent pathways of Arabidopsis. Development. 2003;130:4859-69 pubmed..These results suggest a combinatorial model for TTG1-dependent pathway regulation by this trio of partially functionally redundant bHLH proteins. ..
- Lee W, Ahlquist P. Membrane synthesis, specific lipid requirements, and localized lipid composition changes associated with a positive-strand RNA virus RNA replication protein. J Virol. 2003;77:12819-28 pubmed..This localized UFA depletion helps to explain why BMV RNA replication is more sensitive than cell growth to reduced UFA levels. The results imply that 1a preferentially interacts with one or more types of membrane lipids...
- Hong Z, Geisler Lee C, Zhang Z, Verma D. Phragmoplastin dynamics: multiple forms, microtubule association and their roles in cell plate formation in plants. Plant Mol Biol. 2003;53:297-312 pubmed..Whereas the DRP1 subfamily members are involved in tubulization of membranes, DRP2 may be involved in endocytosis and membrane recycling via clathrin-coated vesicles...
- Grabarek Z. Structure of a trapped intermediate of calmodulin: calcium regulation of EF-hand proteins from a new perspective. J Mol Biol. 2005;346:1351-66 pubmed publisher..The model allows for a significant independence of the Ca2+-binding sites in a two-EF-hand domain...
