Human Polyclonal CACNA1S Primary Antibody for IF (p), IHC (p) - ABIN1387901
Lobeck, Donnelly, Dupree, Mahe, McNeal, Mohanty, Tiao: Rhesus rotavirus VP6 regulates ERK-dependent calcium influx in cholangiocytes. in Virology 2016
Cav1.1 is specified for the excitation-contraction coupling of skeletal muscles, and has been a prototype in the structural investigations of Cav (show CA5A Antibodies) channels. This article summarized the recent advances in the structural elucidation of Cav1.1 and the mechanistic insights derived from the 3.6 A structure obtained using single-particle, electron cryomicroscopy.
he ryanodine receptor 1 (RyR1 (show RYR1 Antibodies)) is mainly expressed in the sarcoplasmic reticulum (SR) of skeletal muscle and is a calcium release channel (show RYR1 Antibodies) which is coupled to the dihydropyridine receptor (CACNA1S) in the T-tubule of the sarcolemma.
review of the pharmacogenetics and pathophysiology of CACNA1S mutations in malignant hyperthermia susceptibility type 5 (MHS5); several mutations are known to be risk factors for increased susceptibility; at present, one or at most six CACNA1S mutations display significant linkage or association either to clinically diagnosed MH or to MHS (show RYR1 Antibodies)
Study used structure modeling and MD simulations to predict pathogenic omega-currents in CaV1.1 and CaV1.3 (show CACNA1D Antibodies) Ca(2 (show CA2 Antibodies)+) channels bearing several S4 charge mutations: omega-currents conducted in resting state, but not during voltage-sensing domain activation. Mechanism responsible depends on the number of charges in S4, the position of the mutated S4 charge and countercharges, and the nature of the replacing amino acid.
Study identified by exome sequencing both recessive and dominant CACNA1S mutations as a cause of a congenital myopathy characterized by peculiar morphological hallmarks in a cohort of 11 patients from 7 families.
whole-exome next-generation sequencing was used to identify a mutation in the CACNA1S gene, R900S, which is a rare mutation associated with hypokalemic periodic paralysis; study provides further evidence for the phenotypic variation and pharmacogenomics of hypokalemic periodic paralysis
These results provide new insights into the role of muscle-specific (show EIF3K Antibodies) proteins on the structural arrangement of alpha1S intracellular loops and point to a new conformational effect of the beta1a subunit in supporting skeletal muscle excitation-contraction coupling.
CACNA1S and SCN4A (show SCN4A Antibodies) mutations are relatively rare in patients with hypokalemic periodic paralysis
The authors found one and three rare variants of unknown significance in CACNA1S in the Malignant Hyperthermia and Exertional Heat cohorts
Defects in the genes coding for the skeletal muscle ryanodine receptor (show RYR1 Antibodies) and alpha 1 subunit of the dihydropyridine receptor (CACNA1S) have been identified as causative for malignant hyperthermia.
Physical interaction of junctophilin and the CaV1.1 C terminus is crucial for skeletal muscle contraction.
The DHPR (show QDPR Antibodies) functions as a voltage sensor to trigger muscle contraction and as a Ca(2 (show CA2 Antibodies)+) channel.
TnT3 regulates expression of Cav1.1 in skeletal muscle, this regulation is impaired in aging.
Immunohistochemistry and western blotting after expression of GPR179 (show GPR179 Antibodies) in HEK293T cells indicate that the CACNA1S antibody used here and in the retinal studies published to date, cross-reacts with GPR179 (show GPR179 Antibodies).
TnT3 regulates transcription of Cacna1s, the gene encoding Cav1.1. Knocking down TnT3 in vivo downregulated Cav1.1.
mutating residue E4242 affects RyR1 (show RYR1 Antibodies) structures critical for retrograde communication with CaV1.1
Events occurring locally in the skeletal muscle of SOD1 mutant mice contribute to the impairment of CaV1.1 function in ALS muscle independently of innervation status.
Knockdown of Cav1.1 channels in T cells abrogated calcium entry after TCR stimulation, suggesting that Cav1.1 channels are controlled by T cell receptor signaling
Treatment of MSC (show MSC Antibodies) with BMP4 (show BMP4 Antibodies) caused a significant increase in expression of Cav1.2 (show CACNA1C Antibodies), a delay in expression of Cav1.1, and a reduction in the duration of calcium transients when extracellular calcium was removed
This gene encodes one of the five subunits of the slowly inactivating L-type voltage-dependent calcium channel in skeletal muscle cells. Mutations in this gene have been associated with hypokalemic periodic paralysis, thyrotoxic periodic paralysis and malignant hyperthermia susceptibility.
