Disulfide-Linked Head-to-Head Multimerization in the Mechanism of Ion Channel Clustering by PSD-95
, 1997 The PSD-95/SAP90 family of PDZ-containing proteins is directly involved in the clustering of specific ion channels at synapses. We report that channel clustering depends on a conserved N-terminal domain of PSD-95 that mediates multimerization and ...

Cytoskeleton, EarlyView.ABSTRACT Post‐translational modifications (PTMs) to tubulin subunits in microtubule filaments are thought to comprise a component of the tubulin code that specifies microtubule functions in cell physiology and animal development. Acetylation of Lysine‐40 (K40) on α‐tubulin (αTub‐K40ac) and glutamylation of both α‐ and β‐tubulin are two tubulin PTMs of ...

Multimeric xanthates as carbonic anhydrase inhibitors [PDF]
Journal of Enzyme Inhibition and Medicinal Chemistry, 2015 The field of multivalent inhibition of enzymes is growing exponentially from the first reported multivalent effect on a glycosidase enzyme. However, the investigations have generally remained restricted to carbohydrate-processing enzymes. Carbonic anhydrases are ubiquitous metallo-enzymes involved in many key biological processes, that catalyze the ...

Arabidopsis AUGMIN8 Contains Two Independent Microtubule Association Domains
Cytoskeleton, EarlyView.ABSTRACT Plant cells create a plasma membrane‐associated network of microtubules that are nucleated by γ‐tubulin ring complexes primarily through microtubule‐dependent microtubule nucleation (MDMN). This dynamic array organizes into specific patterns in response to developmental and environmental cues to influence primary cell wall construction.

The effect of exon 7 deletion during the evolution of TRIMCyp fusion proteins on viral restriction, cytoplasmic body formation and multimerization. [PDF]
PLoS ONE, 2015 TRIMCyp is a fusion protein consisting of the TRIM5 gene product and retrotransposed Cyclophilin A (CypA). Two primate TRIMCyp fusion proteins with varying anti-HIV-1 activities independently evolved in owl monkeys and Old World monkeys. In addition, Old

Protocol for Reconstituting Adaptor‐Mediated Activation of Full‐Length Kinesin‐1
Cytoskeleton, EarlyView.ABSTRACT Kinesin‐1 is a member of the kinesin superfamily that plays an essential role in intracellular cargo transport. In the absence of cargo, Kinesin‐1 exhibits low motor activity due to autoinhibition. Multiple studies have demonstrated that adaptor proteins, which link cargos to Kinesin‐1, can activate Kinesin‐1 by releasing the autoinhibition ...

Multimeric Hemicellulases Facilitate Biomass Conversion [PDF]
Applied and Environmental Microbiology, 2009 ABSTRACT Two highly active trifunctional hemicellulases were constructed by linking the catalytic portion of a xylanase with an arabinofuranosidase and a xylosidase, using either flexible peptide linkers or linkers containing a cellulose-binding domain.

Developmental Dynamics, EarlyView.Abstract Background The promoters and enhancers of heat shock genes, such as the 1.5‐kb promoter of the zebrafish hsp70l gene, are valuable tools for temporal activation of transgenes. It has been widely purported that heat shock treatments result in ubiquitous expression of hsp70l‐driven transgenes.

Retrovirology, 2008 Background The formation of new infectious human immunodeficiency type 1 virus (HIV-1) mainly relies on the homo-multimerization of the viral structural polyprotein Pr55Gag and on the recruitment of host factors.

Placement of leucine zipper motifs at the carboxyl terminus of HIV-1 protease significantly reduces virion production. [PDF]
PLoS ONE, 2012 Natural HIV-1 protease (PR) is homodimeric. Some researchers believe that interactions between HIV-1 Gag-Pol molecules trigger the activation of embedded PR (which mediates Gag and Gag-Pol cleavage), and that Gag-Pol assembly domains outside of PR may ...
