RT "Arrhythmogenic calmodulin mutations impede activation of small-conductance
RT calcium-activated potassium current.";
RL Heart Rhythm 13:1716-1723(2016).
CC -!- FUNCTION: Calmodulin mediates the control of a large number of enzymes,
CC ion channels, aquaporins and other proteins through calcium-binding.
CC Among the enzymes to be stimulated by the calmodulin-calcium complex
CC are a number of protein kinases and phosphatases. Together with CCP110
CC and centrin, is involved in a genetic pathway that regulates the
CC centrosome cycle and progression through cytokinesis (PubMed:16760425).
CC Mediates calcium-dependent inactivation of CACNA1C (PubMed:26969752).
CC Positively regulates calcium-activated potassium channel activity of
CC KCNN2 (PubMed:27165696). {ECO:0000269|PubMed:16760425,
CC ECO:0000269|PubMed:26969752, ECO:0000269|PubMed:27165696}.
CC -!- SUBUNIT: Interacts with MYO1C, MYO5A and RRAD. Interacts with MYO10 (By
CC similarity). Interacts with CEP97, CCP110, TTN/titin and SRY
CC (PubMed:9804419, PubMed:12871148, PubMed:15746192, PubMed:16760425,
CC PubMed:17719545). Interacts with USP6; the interaction is calcium
CC dependent (PubMed:16127172). Interacts with CDK5RAP2 (PubMed:20466722).
CC Interacts with SCN5A (By similarity). Interacts with RYR1
CC (PubMed:18650434). Interacts with FCHO1 (PubMed:22484487). Interacts
CC with MIP in a 1:2 stoichiometry; the interaction with the cytoplasmic
CC domains from two MIP subunits promotes MIP water channel closure (By
CC similarity). Interacts with ORAI1; this may play a role in the
CC regulation of ORAI1-mediated calcium transport (By similarity).
CC Interacts with IQCF1 (By similarity). Interacts with SYT7 (By
CC similarity). Interacts with CEACAM1 (via cytoplasmic domain); this
CC interaction is in a calcium dependent manner and reduces homophilic
CC cell adhesion through dissociation of dimer (By similarity). Interacts
CC with RYR2; regulates RYR2 calcium-release channel activity
CC (PubMed:27516456, PubMed:18650434, PubMed:26164367). Interacts with
CC PCP4; regulates calmodulin calcium-binding (PubMed:27876793). Interacts
CC with the heterotetrameric KCNQ2 and KCNQ3 channel; the interaction is
CC calcium-independent, constitutive and participates in the proper
CC assembly of a functional heterotetrameric M channel (PubMed:27564677).

CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton, spindle
CC {ECO:0000269|PubMed:16760425}. Cytoplasm, cytoskeleton, spindle pole
CC {ECO:0000269|PubMed:16760425}. Cytoplasm, cytoskeleton, microtubule
CC organizing center, centrosome {ECO:0000269|PubMed:14654843}.
CC Note=Distributed throughout the cell during interphase, but during
CC mitosis becomes dramatically localized to the spindle poles and the
CC spindle microtubules.
CC -!- PTM: Ubiquitination results in a strongly decreased activity.
CC {ECO:0000250}.
CC -!- PTM: Phosphorylation results in a decreased activity. {ECO:0000250}.
CC -!- DISEASE: Long QT syndrome 15 (LQT15) [MIM:616249]: A form of long QT
CC syndrome, a heart disorder characterized by a prolonged QT interval on
CC the ECG and polymorphic ventricular arrhythmias. They cause syncope and
CC sudden death in response to exercise or emotional stress, and can
CC present with a sentinel event of sudden cardiac death in infancy.
CC {ECO:0000269|PubMed:23388215, ECO:0000269|PubMed:24917665,
CC ECO:0000269|PubMed:26164367, ECO:0000269|PubMed:26969752,
CC ECO:0000269|PubMed:27165696, ECO:0000269|PubMed:27516456}. Note=The
CC disease is caused by variants affecting the gene represented in this
CC entry. Mutations in CALM2 are the cause of LQT15.
CC -!- MISCELLANEOUS: This protein has four functional calcium-binding sites.
CC {ECO:0000269|PubMed:1474585}.
CC -!- SIMILARITY: Belongs to the calmodulin family. {ECO:0000305}.
