CACNA1F encodes the alpha-1F subunit of voltage-gated L-type calcium channels, also known as Cav1.4. This protein forms the pore-forming core of the calcium channel complex and is essential for calcium influx in response to membrane depolarization. The CACNA1F protein contains 2,166 amino acids and represents the primary calcium-conducting component of Cav1.4 channels, which are critically important for synaptic transmission and retinal signaling.
CACNA1F forms L-type voltage-gated calcium channels (Cav1.4) that mediate:
CACNA1F exhibits distinctive expression patterns:
The highest expression is in retinal photoreceptors:
Lower expression in:
CACNA1F mutations are primarily associated with visual disorders:
Although primarily retinal, CACNA1F dysregulation may affect:
Minor cardiac expression suggests potential roles in:
CACNA1F assembles with auxiliary subunits to form functional channels:
Cav1.4 (alpha-1F) + Beta2/Beta4 + Alpha2-Delta4
The alpha-1F subunit contains:
CACNA1F interacts with:
CACNA1F interacts with:
Cav1.4 channels represent potential targets for:
