Calcium-activated potassium channel

Following calcium influx, the consecutive activation of KCNN4 channel leads to a hyperpolarization of the cell membrane potential and hence an increase of the electrical driving force for further calcium … The inward rectification could be due to a blockade of the outward current by intracellular divalent cations such as calcium and magnesium and could also be due to an intrinsic property of the channel

Calcium/manganese antiporter SLC30A10

Calcium:manganese antiporter of the plasma membrane mediating the efflux of intracellular manganese coupled to an active extracellular calcium exchange (PubMed:30755481). … Could also have an intracellular zinc ion transporter activity, directly regulating intracellular zinc ion homeostasis and more indirectly various signaling pathway and biological processes (PubMed:22427991

Basement membrane-specific heparan sulfate proteoglycan core protein

Component of the glomerular basement membrane (GBM), responsible for the fixed negative electrostatic membrane charge, and which provides a barrier which is both size- and charge-selective. … It serves as an attachment substrate for cells. Plays essential roles in vascularization. Critical for normal heart development and for regulating the vascular response to injury.

Calcium-dependent secretion activator 1

Calcium-binding protein involved in exocytosis of vesicles filled with neurotransmitters and neuropeptides. … ATP-dependent priming and participates in DCVs-membrane fusion.

Soluble calcium-activated nucleotidase 1

Calcium-dependent nucleotidase with a preference for ribonucleosides diphosphate UDP, GDP and IDP, while having very low activity towards ADP and CDP (PubMed:12234496, PubMed:15006348, PubMed:15248776, … Does not hydrolyze AMP and GMP (PubMed:12234496). Involved in proteoglycan synthesis (PubMed:22539336)

Calcium-dependent secretion activator 2

Calcium-binding protein involved in exocytosis of vesicles filled with neurotransmitters and neuropeptides. … Regulates neurotrophin release from granule cells leading to regulate cell differentiation and survival during cerebellar development.

Calcium-dependent protein kinase 4

Calcium-dependent protein kinase which acts as a sensor and effector of intracellular Ca(2+) levels probably in part downstream of cGMP-activated PKG kinase (PubMed:19307175, PubMed:19666141). … Plays a central role in the host erythrocytes and hepatocytes infection cycles, sexual reproduction and mosquito transmission of the parasite.

Calcium-dependent protein kinase 1

In late schizonts, phosphorylates PKA regulatory subunit PKAr in a calcium-dependent manner, which may contribute to the dissociation of regulatory PKAr and catalytic PKAc subunits and promote the activation … Calcium-dependent protein kinase which acts as a sensor and effector of intracellular Ca(2+) levels probably in part downstream of cGMP-activated PKG kinase (PubMed:18768477, PubMed:19307175, PubMed:28680058

Plasma membrane calcium-transporting ATPase

Plays dual roles in osteoclast differentiation and survival by regulating RANKL-induced calcium oscillations in preosteoclasts and mediating calcium extrusion in mature osteoclasts (By similarity). … May play a role in synaptic transmission by modulating calcium and proton dynamics at the synaptic vesicles
