T-type Ca2+ Channels: T for Targetable [PDF]
, 2018 In the last decade TTCC have been unveiled as key regulators of cancer cells biology and thus have been proposed as chemotherapeutic targets. Indeed in vitro and in vivo studies indicate that TTCC pharmacological blockers have a negative impact on the ...

Ca2+ Dependence of the Ca2+-selective TRPV6 Channel [PDF]
Journal of Biological Chemistry, 2004 Microfluorimetry and patch-clamp experiments were performed on TRPV6-expressing HEK cells to determine whether this Ca(2+)-sensing Ca(2+) channel is constitutively active. Intact cells loaded with fura-2 had an elevated intracellular free Ca(2+) concentration ([Ca(2+)](i)), which decreased to the same level such as in non-transfected cells if external ...

TRPC1 regulates calcium-activated chloride channels in salivary gland cells [PDF]
, 2015 Calcium-activated chloride channel (CaCC) plays an important role in modulating epithelial secretion. It has been suggested that in salivary tissues, sustained fluid secretion is dependent on Ca2+ influx that activates ion channels such as CaCC to ...

TRPV4, TRPC1, and TRPP2 assemble to form a flow-sensitive heteromeric channel [PDF]
, 2014 Transient receptor potential (TRP) channels, a superfamily of ion channels, can be divided into 7 subfamilies, including TRPV, TRPC, TRPP, and 4 others. Functional TRP channels are tetrameric complexes consisting of 4 pore-forming subunits.

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Weft, Warp & Weave: The Intricate Tapestry of Calcium Channels Regulating T Lymphocyte Function
Frontiers in Immunology, 2013 Calcium (Ca2+) is a universal second messenger important for T lymphocyte homeostasis, activation, proliferation, differentiation and apoptosis. The events surrounding Ca2+ mobilization in lymphocytes are tightly regulated and involve the coordination of

An Exclusion Zone for Ca2+ Channels around Docked Vesicles Explains Release Control by Multiple Channels at a CNS Synapse. [PDF]
PLoS Computational Biology, 2015 The spatial arrangement of Ca2+ channels and vesicles remains unknown for most CNS synapses, despite of the crucial importance of this geometrical parameter for the Ca2+ control of transmitter release.

Ca2+ transients are not required as signals for long-term neurite outgrowth from cultured sympathetic neurons [PDF]
, 1990 A method for clamping cytosolic free Ca2+ ([Ca2+]i) in cultures of rat sympathetic neurons at or below resting levels for several days was devised to determine whether Ca2+ signals are required for neurite outgrowth from neurons that depend on Nerve ...
