A heterotrimeric G protein, G alpha i-3, on Golgi membranes regulates the secretion of a heparan sulfate proteoglycan in LLC-PK1 epithelial cells [PDF]
, 1991 A heterotrimeric G-alpha-i subunit, alpha-i-3, is localized on Golgi membranes in LLC-PK1 and NRK epithelial cells where it colocalizes with mannosidase II by immunofluorescence.

Advanced Science, Volume 13, Issue 13, 3 March 2026.This study revealed that low expression of YTHDC1 in TMZ‐resistant GBM cells leads to increased FSCN1 expression, which is suppressed by m6A modification. FSCN1 activates the CDC42/N‐WASP/Arp2/3 axis in the cell nucleus by recruiting the guanine nucleotide exchange factor (GEF) family member FGD1, thereby promoting F‐actin polymerization in the nucleus.

Effects of post-translational modifications catalysed by pollen transglutaminase on the functional properties of microtubules and actin filaments [PDF]
, 2009 TGases (transglutaminases) are a class of calcium-dependent enzymes that catalyse the interactions between acyl acceptor glutamyl residues and amine donors, potentially making crosslinks between proteins.

Novel role of Ras-GTPase Activating Protein SH3 Domain-Binding Protein G3BP in adhesion and migration of 32D myeloid progenitor cells [PDF]
, 2012 Rho GTPases are involved in homing and mobilization of hematopoietic stem and progenitor cells due to their impact on cytoskeleton remodeling. We have previously shown that inhibition of Rho, Rac and Cdc42 clearly impairs adhesion of normal and leukemic ...

Stochastic kinetics of ribosomes: single motor properties and collective behavior [PDF]
, 2009 Synthesis of protein molecules in a cell are carried out by ribosomes. A ribosome can be regarded as a molecular motor which utilizes the input chemical energy to move on a messenger RNA (mRNA) track that also serves as a template for the polymerization ...

Dysregulated GPCR Signaling and Therapeutic Options in Uveal Melanoma. [PDF]
, 2017 Uveal melanoma is the most common primary intraocular malignant tumor in adults and arises from the transformation of melanocytes in the uveal tract. Even after treatment of the primary tumor, up to 50% of patients succumb to metastatic disease.

Epac, Rap and Rab3 act in concert to mobilize calcium from sperm's acrosome during exocytosis [PDF]
, 2014 BACKGROUND: Exocytosis of sperm's single secretory granule or acrosome (acrosome reaction, AR) is a highly regulated event essential for fertilization. The AR begins with an influx of calcium from the extracellular milieu and continues with the synthesis

Nucleotide– and Mal3-dependent changes in fission yeast microtubules suggest a structural plasticity view of dynamics [PDF]
, 2017 Using cryo-electron microscopy, we characterize the architecture of microtubules assembled from Schizosaccharomyces pombe tubulin, in the presence and absence of their regulatory partner Mal3.

Signaling pathways for transduction of the initial message of the glycocode into cellular responses [PDF]
, 1998 The sugar units of glycan structures store information and establish an alphabet of life. The language of the oligosaccharide coding units is deciphered by receptors such as lectins and the decoded message can be transduced by multiple signaling pathways.

Measuring ligand efficacy at the mu-opioid receptor using a conformational biosensor. [PDF]
, 2018 The intrinsic efficacy of orthosteric ligands acting at G-protein-coupled receptors (GPCRs) reflects their ability to stabilize active receptor states (R*) and is a major determinant of their physiological effects.
