Today, CACNB1 is a topic of great interest and relevance in various areas of society. Its impact has spread globally, generating debates, reflections and actions around its implications. In this article, we will explore in detail and critically the role of CACNB1 in our current reality, analyzing its different facets, perspectives and consequences. Its influence in various contexts will be examined, as well as possible solutions and alternatives to address its challenges. CACNB1 has positioned itself as a central issue on the public and private agenda, and it is essential to understand its scope and dynamics to be able to address it effectively and responsibly.
Voltage-dependent L-type calcium channel subunit beta-1 is a protein that in humans is encoded by the CACNB1gene.[5][6][7]
The protein encoded by this gene belongs to the calcium channel beta subunit family. It plays an important role in the calcium channel by modulating G protein inhibition, increasing peak calcium current, controlling the alpha-1 subunit membrane targeting and shifting the voltage dependence of activation and inactivation. Alternative splicing occurs at this locus and three transcript variants encoding three distinct isoforms have been identified.[7]
Mutations in CACNB1 are known to cause the following conditions: Malignant Hyperthermia; Congenital Myopathy; Alzheimer's Disease; Autism Spectrum Disorder.[8]
