Summaries for CACNB4 Gene

Entrez Gene Summary for CACNB4 Gene

  • This gene encodes a member of the beta subunit family of voltage-dependent calcium channel complex proteins. Calcium channels mediate the influx of calcium ions into the cell upon membrane polarization and consist of a complex of alpha-1, alpha-2/delta, beta, and gamma subunits in a 1:1:1:1 ratio. Various versions of each of these subunits exist, either expressed from similar genes or the result of alternative splicing. The protein encoded by this locus plays an important role in calcium channel function 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. Certain mutations in this gene have been associated with idiopathic generalized epilepsy (IGE), juvenile myoclonic epilepsy (JME), and episodic ataxia, type 5. [provided by RefSeq, Aug 2016]

GeneCards Summary for CACNB4 Gene

CACNB4 (Calcium Voltage-Gated Channel Auxiliary Subunit Beta 4) is a Protein Coding gene. Diseases associated with CACNB4 include Episodic Ataxia, Type 5 and Epilepsy, Idiopathic Generalized 9. Among its related pathways are DREAM Repression and Dynorphin Expression and Sweet Taste Signaling. GO annotations related to this gene include protein kinase binding and high voltage-gated calcium channel activity. An important paralog of this gene is CACNB2.
