Structure and function of potassium and calcium channels [PDF]
, 2005 In this thesis, potassium channels human Kv2.1 and rat Kv2.1, along with calcium channels Ca, 1.2, Ca, 3.1, and chimeras have been studied. These channels were expressed in Xenopuso ocytesf or electrophysiological experiments using two electrode voltage

Physiology, 2017 In this review article, we discuss the different gene products and translational variants of ORAI proteins and their contribution to the makeup of different native calcium-conducting channels with distinct compositions and modes of activation. We also review the different modes of regulation of these distinct calcium channels and their impact on ...

Tissue-specific expression of calcium channels [PDF]
, 1993 The high-voltage-activated calcium channel is a multimeric protein complex containing 1, 2/δ, β, and γ subunits. The 1 subunit is the ion conduction channel and contains the binding sites for calcium channel blockers and toxins.

The involvement of TRP channels in bone homeostasis
Frontiers in Endocrinology, 2012 Calcium and bone homeostasis are intimately related. On the one hand, bone relies on a sufficient supply of calcium to maintain its structural and mechanical properties and thus largely depends on calcium absorption in the intestine and calcium ...

TRPV5 and TRPV6 calcium-selective channels. [PDF]
, 2017 Calcium Entry Channels in Non-Excitable Cells focuses on methods of investigating the structure and function of non-voltage gated calcium channels. Each chapter presents important discoveries in calcium entry pathways, specifically dealing with the ...

Regulation of Presynaptic Calcium Channels by Synaptic Proteins
Journal of Pharmacological Sciences, 2003 Calcium entry into nerve termini via voltage gated calcium channels is an essential step in neurotransmission. Consequently, second messenger regulation of calcium channel activity modulates synaptic activity.

Calcium channels in lymphocytes [PDF]
Immunology, 2001 On B and T lymphocytes, ligation of the antigen receptor (AgR) induces a biphasic Ca2+ response. In the initial phase there is a large elevation in the intracellular Ca2+ concentration as a consequence of Ca2+ release from intracellular stores. This is followed by a lower, but prolonged elevation that is dependent on extracellular Ca2+.1,2 This simple ...

Presynaptic calcium channels [PDF]
Neuroscience Research, 2018 Presynaptic Ca2+ entry occurs through voltage-gated Ca2+ (CaV) channels which are activated by membrane depolarization. Depolarization accompanies neuronal firing and elevation of Ca2+ triggers neurotransmitter release from synaptic vesicles. For synchronization of efficient neurotransmitter release, synaptic vesicles are targeted by presynaptic Ca2 ...

Ion Channels of Pituitary Gonadotrophs and Their Roles in Signaling and Secretion
Frontiers in Endocrinology, 2017 Gonadotrophs are basophilic cells of the anterior pituitary gland specialized to secrete gonadotropins in response to elevation in intracellular calcium concentration.
