Tissue Specificity | Highly expressed in heart and brain, and at lower levels in lung. |
Post Translational Modifications | Regulated through phosphorylation at Thr-549 by CaMK2D. |
Function | Beta subunit of voltage-dependent calcium channels which contributes to the function of the calcium channel by increasing peak calcium current. Plays a role in shifting voltage dependencies of activation and inactivation of the channel. May modulate G protein inhibition. May contribute to beta-adrenergic augmentation of Ca(2+) influx in cardiomyocytes, thereby regulating increases in heart rate and contractile force. Involved in membrane targeting of the alpha-1 subunit CACNA1C. |
