Also known as MGC40084DOSBARP
Summary
CBARP (CACN subunit beta associated regulatory protein, HGNC:28617) is a protein-coding gene on chromosome 19p13.3, encoding Voltage-dependent calcium channel beta subunit-associated regulatory protein (Q8N350). Negatively regulates voltage-gated calcium channels by preventing the interaction between their alpha and beta subunits.
Predicted to enable transmembrane transporter binding activity. Predicted to be involved in negative regulation of calcium ion-dependent exocytosis and negative regulation of voltage-gated calcium channel activity. Predicted to be located in growth cone and secretory granule. Predicted to be active in plasma membrane.

Genetic regulation across tissues (GTEx eQTL / sQTL)
CBARP is an eGene in GTEx v10 — its expression is genetically regulated (eQTL) in 10 tissues and its splicing (sQTL) in 5 (q < 0.05). Strongest associations first; slope = normalized effect of the lead variant’s alternative allele.

UniProt curated annotations — full annotation on UniProt →
Function. Negatively regulates voltage-gated calcium channels by preventing the interaction between their alpha and beta subunits. Thereby, negatively regulates calcium channels activity at the plasma membrane and indirectly inhibits calcium-regulated exocytosis.
Subunit / interactions. Interacts with voltage-dependent calcium channels CACNB1, CACNB2, CACNB3 and CACNB4 beta subunits; prevents their interaction with the CACNA1C alpha subunit thereby negatively regulating the activity of the corresponding calcium channels.
Subcellular location. Cytoplasmic vesicle. Secretory vesicle. Synaptic vesicle membrane. Cell membrane. Cell projection. Growth cone.
