Distinct Roles for KASH Proteins SINE1 and SINE2 in Guard Cell Actin Reorganization, Calcium Oscillations, and Vacuolar Remodeling

open access: yesFrontiers in Plant Science, 2022
The linker of nucleoskeleton and cytoskeleton (LINC) complex is a protein complex spanning the inner and outer membranes of the nuclear envelope. Outer nuclear membrane KASH proteins interact in the nuclear envelope lumen with inner nuclear membrane SUN ...

Actin dynamics: Assembly and disassembly of actin networks [PDF]

open access: yesCurrent Biology, 2000
Assembly of branched actin filament networks at the leading edge of migrating cells requires stimulation of the Arp2/3 complex by WASp proteins, in concert with the WASp activators Cdc42, PIP(2) and profilin. Network disassembly and debranching appears to be linked to actin-bound ATP hydrolysis as filaments age.

Purification tags markedly affect self‐aggregation of CPEB3

open access: yesFEBS Letters, EarlyView.
Although recombinant proteins are used to study protein aggregation in vitro, uncleaved tags can interfere with accurate interpretation. Our findings demonstrate that His₆‐GFP and His₁₂ tags significantly affect liquid droplet and amyloid fibril formation in the intrinsically disordered region (IDR) of mouse cytoplasmic polyadenylation element‐binding ...

Intron‐oriented HTLV‐1 integration in an adult T‐cell leukemia/lymphoma cell line sustains expression of intact ift81 mRNA

open access: yesFEBS Letters, EarlyView.
In the adult T‐cell leukemia/lymphoma (ATL) cell line ED, the human T‐cell leukemia virus type 1 (HTLV‐1) provirus was integrated into the intron of the ift81 gene in the antisense orientation. Despite this integration, both the intact ift81 and the viral oncogene hbz were simultaneously expressed, likely due to the functional insufficiency of viral ...

Epsin deficiency impairs endocytosis by stalling the actin-dependent invagination of endocytic clathrin-coated pits

open access: yeseLife, 2014
Epsin is an evolutionarily conserved endocytic clathrin adaptor whose most critical function(s) in clathrin coat dynamics remain(s) elusive. To elucidate such function(s), we generated embryonic fibroblasts from conditional epsin triple KO mice.

Interactions between β-arrestin proteins and the cytoskeletal system, and their relevance to neurodegenerative disorders

open access: yesFrontiers in Endocrinology, 2023
β-arrestins, which have multiple cellular functions, were initially described as proteins that desensitize rhodopsin and other G protein-coupled receptors.

The Structure of Actin [PDF]

open access: yesBiophysical Journal, 2014
The protein actin exists as both a monomer (G-actin) and polymer (F-actin). There have been more than 80 different crystal structures of G-actin and related homologs over the years, and at least 4 different structures/models for F-actin have been proposed using a combination of techniques.

Cyclic nucleotide signaling as a drug target in retinitis pigmentosa

open access: yesFEBS Letters, EarlyView.
Disruptions in cGMP and cAMP signaling can contribute to retinal dysfunction and photoreceptor loss in retinitis pigmentosa. This perspective examines the mechanisms and evaluates emerging evidence on targeting these pathways as a potential therapeutic strategy to slow or prevent retinal degeneration.
