Parvalbumin alpha; In muscle, parvalbumin is thought to be involved in relaxation after contraction. It binds two calcium ions; Belongs to the parvalbumin family.

Transient receptor potential cation channel subfamily V member 6; Calcium selective cation channel that mediates Ca(2+) uptake in various tissues, including the intestine. Important for normal Ca(2+) ion homeostasis in the body, including bone and skin (By similarity). The channel is activated by low internal calcium level, probably including intracellular calcium store depletion, and the current exhibits an inward rectification. Inactivation includes both a rapid Ca(2+)-dependent and a slower Ca(2+)-calmodulin-dependent mechanism; the latter may be regulated by phosphorylation. In vit [...]

45 kDa calcium-binding protein; May regulate calcium-dependent activities in the endoplasmic reticulum lumen or post-ER compartment; Belongs to the CREC family.

Calretinin; Calretinin is a calcium-binding protein which is abundant in auditory neurons; Belongs to the calbindin family.

Calmodulin-1; Calmodulin mediates the control of a large number of enzymes, ion channels, aquaporins and other proteins through calcium-binding. Among the enzymes to be stimulated by the calmodulin-calcium complex are a number of protein kinases and phosphatases. Together with CCP110 and centrin, is involved in a genetic pathway that regulates the centrosome cycle and progression through cytokinesis. Mediates calcium-dependent inactivation of CACNA1C. Positively regulates calcium-activated potassium channel activity of KCNN2.

Calmodulin-like protein 4; Calmodulin like 4; Belongs to the calmodulin family.

Transient receptor potential cation channel subfamily V member 5; Constitutively active calcium selective cation channel thought to be involved in Ca(2+) reabsorption in kidney and intestine. Required for normal Ca(2+) reabsorption in the kidney distal convoluted tubules (By similarity). The channel is activated by low internal calcium level and the current exhibits an inward rectification. A Ca(2+)-dependent feedback regulation includes fast channel inactivation and slow current decay (By similarity). Heteromeric assembly with TRPV6 seems to modify channel properties. TRPV5-TRPV6 hete [...]

Calmodulin-like protein 3; May function as a specific light chain of unconventional myosin-10 (MYO10), also enhances MYO10 translation, possibly by acting as a chaperone for the emerging MYO10 heavy chain protein. May compete with calmodulin by binding, with different affinities, to cellular substrates.
