Data show that mutant variant V156A results in instability of protein subdomains of beta1a subunit leading to a phenotype of Ca(2+) dysregulation that partly resembles that of other malignant hypertension-linked mutations of DHPR alpha1S subunit.

The present study reveals that the C-terminal of the beta1a subunit changes conformation in the presence of RyR1 consistent with an interaction between the C-terminal of beta1a and RyR1 in resting myotubes.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
