Transient receptor potential channels (TRP channels) are a group of ion channels located mostly on the plasma membrane of numerous animal cell types. Most of these are grouped into two broad groups: Group 1 includes TRPC ( "C" for canonical), TRPV ("V" for vanilloid), TRPVL ("VL" for vanilloid-like), TRPM ("M" for melastatin), TRPS ("S" for soromelastatin), TRPN ("N" for mechanoreceptor ...
Ryanodine receptors mediate the release of calcium ions from the sarcoplasmic reticulum and endoplasmic reticulum, an essential step in muscle contraction. [1] In skeletal muscle, activation of ryanodine receptors occurs via a physical coupling to the dihydropyridine receptor (a voltage-dependent, L-type calcium channel), whereas, in cardiac muscle, the primary mechanism of activation is ...
Inositol trisphosphate receptor (InsP3R) is a membrane glycoprotein complex acting as a Ca 2+ channel activated by inositol trisphosphate (InsP3). InsP3R is very diverse among organisms, and is necessary for the control of cellular and physiological processes including cell division, cell proliferation, apoptosis, fertilization, development, behavior, learning and memory.

RYR1 plays a signaling role during embryonic skeletal myogenesis. A correlation exists between RYR1-mediated Ca2+ signaling and the expression of multiple molecules involved in key myogenic signaling pathways. [8] Of these, more than 10 differentially expressed genes belong to the Wnt family which are essential for differentiation.
The N-methyl-D-aspartate receptor (NMDA receptor) – a type of ionotropic glutamate receptor – is a ligand-gated ion channel that is gated by the simultaneous binding of glutamate and a co-agonist (i.e., either D-serine or glycine). [11] Studies show that the NMDA receptor is involved in regulating synaptic plasticity and memory. [12] [13]
Transient receptor potential cation channel, subfamily A, member 1, also known as transient receptor potential ankyrin 1, TRPA1, or The Mustard and Wasabi Receptor, is a protein that in humans is encoded by the TRPA1 (and in mice and rats by the Trpa1) gene. [5] [6] TRPA1 is an ion channel located on the plasma membrane of many human and animal ...
The receptors were first identified as specific molecules through the use of binding studies, in which opiates that had been labeled with radioisotopes were found to bind to brain membrane homogenates. The first such study was published in 1971, using 3 H-levorphanol. [6]
It signals by associating with two FcRγ signaling chains. [10] Another receptor can also bind IgA, although it has higher affinity for another antibody called IgM. [11] This receptor is called the Fc-alpha/mu receptor (Fcα/μR) and is a type I transmembrane protein. With one Ig-like domain in its extracellular portion, this Fc receptor is ...
