Phylogenetic analysis of the SAP30 family of transcriptional regulators reveals functional divergence in the domain that binds the nuclear matrix [PDF]

open access: yes, 2009
Background: Deacetylation of histones plays a fundamental role in gene silencing, and this is mediated by a corepressor complex containing Sin3 as an essential scaffold protein. In this report we examine the evolution of two proteins in this complex, the

Mutational analysis of the carbohydrate binding activity of the tobacco lectin [PDF]

open access: yes, 2010
At present the three-dimensional structure of the tobacco lectin, further referred to as Nictaba, and its carbohydrate-binding site are unresolved. In this paper, we propose a three-dimensional model for the Nictaba domain based on the homology between ...

Effect of Nuclear Export Inhibitor Leptomycin B on the Intracellular Localization of HBV Core Protein into Hepatocytes Cell Line Huh-7 and HepG2 Cells

open access: yesIndonesian Journal of Biotechnology, 2010
Leptomycin B (LMB) was originally discovered as a potent anti-fungal antibiotic from Streptomyces species. The cellular target of LMB has been identified as the nuclear export receptor CRM-1 or exportin-1, which is involved in nuclear trafficking of ...

Identification of a classical bipartite nuclear localization signal in the Drosophila TEA/ATTS protein scalloped. [PDF]

open access: yesPLoS ONE, 2011
Drosophila melanogaster wing development has been shown to rely on the activity of a complex of two proteins, Scalloped (Sd) and Vestigial (Vg). Within this complex, Sd is known to provide DNA binding though its TEA/ATTS domain, while Vg modulates this ...

Structural basis of nuclear import of flap endonuclease 1 (FEN1) [PDF]

open access: yes, 2012
Flap endonuclease 1 (FEN1) is a member of the nuclease family and is structurally conserved from bacteriophages to humans. This protein is involved in multiple DNA-processing pathways, including Okazaki fragment maturation, stalled replication-fork ...

Deletion of the nuclear localization sequence and C-terminus of parathyroid hormone–related protein decreases osteogenesis and chondrogenesis but increases adipogenesis and myogenesis in murine bone marrow stromal cells

open access: yesJournal of Tissue Engineering, 2015
The N-terminus of parathyroid hormone–related protein regulates bone marrow stromal cell differentiation. We hypothesized that the nuclear localization sequence and C-terminus are involved.

Novel localization of formin mDia2: importin β-mediated delivery to and retention at the cytoplasmic side of the nuclear envelope

open access: yesBiology Open, 2015
The formin family proteins are important regulators of actin polymerization that are involved in many cellular processes. However, little is known about their specific cellular localizations.

The Expression and Localization of N-Myc Downstream-Regulated Gene 1 in Human Trophoblasts [PDF]

open access: yes, 2013
The protein N-Myc downstream-regulated gene 1 (NDRG1) is implicated in the regulation of cell proliferation, differentiation, and cellular stress response.
