Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics

FEBS Letters, EarlyView.
Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...

Ryanodine receptors, a family of intracellular calcium ion channels, are expressed throughout early vertebrate development [PDF]

, 2011
Background Calcium signals ([Ca2+]i) direct many aspects of embryo development but their regulation is not well characterised. Ryanodine receptors (RyRs) are a family of intracellular Ca2+ release channels that control the flux of Ca2+ from internal ...

The Ascidian Dihydropyridine-Resistant Calcium Channel as the Prototype of Chordate L-Type Calcium Channel

Neurosignals, 2003
This review describes recent findings on voltage-gated Ca channel (Cav channel) cloned from ascidians, the most primitive chordates. Ascidian L-type like Cav channel has several unusual features: (1). it is closely related to the prototype of chordate L-type Cav channels by sequence alignment; (2). it is resistant to dihydropyridine due to single amino

Autophagy and mitophagy in pancreatic β‐cell homeostasis and their involvement in diabetes pathophysiology

FEBS Letters, EarlyView.
This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.

Inhibition of N- and L-type calcium channels by muscarinic receptor activation in rat sympathetic neurons

, 1992
Modulation of N- and L-type Ca2+ channels by oxotremorine-M (oxo-M) acting on muscarinic receptors and norepinephrine (NE) acting on α-adrenergic receptors was studied in superior cervical ganglion neurons.

Antischistosomal activity of a calcium channel antagonist on schistosomula and adult Schistosoma mansoni worms

Memorias do Instituto Oswaldo Cruz, 2013
Current schistosomiasis control strategies are largely based on chemotherapeutic agents and a limited number of drugs are available today. Praziquantel (PZQ) is the only drug currently used in schistosomiasis control programs.

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

FEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Modeling L-type Calcium Channel with Dihydropyridines [PDF]

Biophysical Journal, 2009
Dyhydropyridines (DHPs) is a major class of L-type calcium channel (LCC) ligands, which have boat-like six-membered ring with NH-group at the stern, aromatic moiety at the bow, and various substituents at the port and starboard sides. DHPs demonstrate antagonistic or agonistic action, which was previously explained as stabilization or destabilization ...

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

FEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...
