Recognizes epitopes at the C-terminal intracellular domain (amino acids 822–835 in mice) .
Cross-reactivity confirmed in human, mouse, and rat samples .
Neurological function: TRPC3 maintains tonic depolarizing currents in basal ganglia neurons, regulating resting membrane potential and firing regularity .
Cardiac effects: Agonist-activated TRPC3 prolongs action potential duration in cardiomyocytes, implicating it in arrhythmogenesis .
Muscle development: TRPC3 knockdown in skeletal muscle cells increases apoptosis via elevated p53 and caspase-3 levels .
Testis development: Inhibition with Pyr3 reduces germ cell numbers by 2.9-fold in male mouse gonads (ex vivo cultures) .
Cell morphology: siRNA-mediated TRPC3 suppression in NT2/D1 cells decreases cell area (12.6% reduction) and volume (15.3% reduction) .
PKG phosphorylation: TRPC3 is phosphorylated at Thr-11 and Ser-263 by protein kinase G, reducing calcium influx by 50–97% in HEK293 cells .
Co-localization: TRPC3 overlaps with TRPC6 in cerebellar Purkinje cells, suggesting functional synergy .
TRPC3 antibodies have identified the channel as a potential target for:
