Molecular mechanism of Gαi activation by non-GPCR proteins with a Gα-Binding and Activating motif [PDF]
, 2017 Heterotrimeric G proteins are quintessential signalling switches activated by nucleotide exchange on Gα. Although activation is predominantly carried out by G-protein-coupled receptors (GPCRs), non-receptor guanine-nucleotide exchange factors (GEFs) have

Frontiers in Cell and Developmental Biology, 2023 The septin family of eukaryotic proteins comprises distinct classes of sequence-related monomers that associate in a defined order into linear hetero-oligomers, which are capable of polymerizing into cytoskeletal filaments. Like actin and ⍺ and β tubulin,

Emerging role of ARHGAP29 in melanoma cell phenotype switching
Molecular Oncology, EarlyView.This study gives first insights into the role of ARHGAP29 in malignant melanoma. ARHGAP29 was revealed to be connected to tumor cell plasticity, promoting a mesenchymal‐like, invasive phenotype and driving tumor progression. Further, it modulates cell spreading by influencing RhoA/ROCK signaling and affects SMAD2 activity. Rho GTPase‐activating protein

PDE6δ-mediated sorting of INPP5E into the cilium is determined by cargo-carrier affinity [PDF]
, 2016 The phosphodiesterase 6 delta subunit (PDE6δ) shuttles several farnesylated cargos between membranes. The cargo sorting mechanism between cilia and other compartments is not understood.

Molecular Oncology, EarlyView.RAS‐targeted therapies have become a clinical reality. Although promising results in patients have been achieved, there are still challenges ahead such as coping with drug resistance. Here we summarize selected RAS inhibitors targeting either individual KRAS mutant isoforms (KRASG12C, KRASG12D, KRASG12V) or exhibiting a wider inhibitory spectrum ...

Tau Avoids the GTP Cap at Growing Microtubule Plus-Ends
iScience, 2020 Summary: Plus-end tracking proteins (+TIPs) associate with the growing end of microtubules and mediate important cellular functions. The majority of +TIPs are directed to the plus-end through a family of end-binding proteins (EBs), which preferentially ...

Computational and Structural Biotechnology Journal, 2021 Ras undergoes interconversion between the active GTP-bound state and the inactive GDP-bound state. This GTPase cycle, which controls the activities of Ras, is accelerated by Ras GTPase-activating proteins (GAPs) and guanine nucleotide exchange factors ...

Activation of phospholipase C beta4 by heterotrimeric GTP-binding proteins [PDF]
, 1994 Transient transfection assays were used to determine how the activity of phospholipase C beta 4, which is preferentially expressed in retina, was regulated.
