Proteins and enzymes this drug interacts with in the body
PMID:10200233 PMID:17187064 PMID:21349352 PMID:22457051 PMID:23280837 PMID:23280838 PMID:34997220 PMID:9843794
In cardiomyocytes, may generate the transient outward potassium current I(To) (By similarity). In neurons, may conduct the transient subthreshold somatodendritic A-type potassium current (ISA) (By similarity). Kinetics properties are characterized by fast activation at subthreshold membrane potentials, rapid inactivation, and quick recovery from inactivation .

Channel properties are modulated by interactions with regulatory subunits .
PMID:17187064 PMID:34997220
Interaction with the regulatory subunits KCNIP1 or KCNIP2 modulates the channel gating kinetics namely channel activation and inactivation kinetics and rate of recovery from inactivation .
PMID:17187064 PMID:34997220
Likewise, interaction with DPP6 modulates the channel gating kinetics namely channel activation and inactivation kinetics PMID:34997220
PMID:27149520 PMID:9670923 PMID:9930755
T-type channels serve pacemaking functions in both central neurons and cardiac nodal cells and support calcium signaling in secretory cells and vascular smooth muscle (Probable).
They may also be involved in the modulation of firing patterns of neurons .
PMID:15048902
In the adrenal zona glomerulosa, participates in the signaling pathway leading to aldosterone production in response to either AGT/angiotensin II, or hyperkalemia PMID:25907736 PMID:27729216
Proteins that transport this drug across cell membranes
PMID:10347222 PMID:12403779 PMID:14578046 PMID:14736710
Mediates the sodium-dependent bicarbonate transport important for pH recovery after acid load as well as for regulation of steady-state pH in the duodenum and vascular smooth muscle cells (By similarity). Plays a key role in macrophage acidification, mediating bicarbonate import into the cytoplasm which is crucial for net acid extrusion and maintenance of cytoplasmic pH during phagocytosis .
PMID:29779931
Provides cellular bicarbonate for de novo purine and pyrimidine synthesis and is a key mediator of de novo nucleotide synthesis downstream of mTORC1 signaling in proliferating cells PMID:35772404
PMID:18577713
Plays a major role in pH regulation in neurons (By similarity). Mediates sodium reabsorption in the renal cortical collecting ducts (By similarity)
PMID:18319254
Has been shown to act as a sodium/bicarbonate cotransporter in exchange for intracellular chloride (By similarity). Has also been shown to act as a sodium/biocarbonate cotransporter which does not couple net influx of bicarbonate to net efflux of chloride, with the observed chloride efflux being due to chloride self-exchange .
PMID:18319254
Controls neuronal pH and may contribute to the secretion of cerebrospinal fluid (By similarity). Acting on presynaptic intracellular pH, it promotes GABA release, reduces the excitability of CA1 pyramidal neurons, and modulates short-term synaptic plasticity (By similarity).
Required in retinal cells to maintain normal pH which is necessary for normal vision (By similarity). In the kidney, likely to mediate bicarbonate reclamation in the apical membrane of the proximal tubules (By similarity)
