Function

FUNCTION: Non-selective calcium permeant cation channel involved in osmotic sensitivity and mechanosensitivity. Activation by exposure to hypotonicity within the physiological range exhibits an outward rectification (PubMed:18826956, PubMed:18695040). Also activated by heat, low pH, citrate and phorbol esters (PubMed:16293632, PubMed:18826956, PubMed:18695040, PubMed:25256292, PubMed:20037586, PubMed:21964574). Increase of intracellular Ca(2+) potentiates currents. Channel activity seems to be regulated by a calmodulin-dependent mechanism with a negative feedback mechanism (PubMed:12724311, PubMed:18826956). Promotes cell-cell junction formation in skin keratinocytes and plays an important role in the formation and/or maintenance of functional intercellular barriers (By similarity). Acts as a regulator of intracellular Ca(2+) in synoviocytes (PubMed:19759329). Plays an obligatory role as a molecular component in the nonselective cation channel activation induced by 4-alpha-phorbol 12,13-didecanoate and hypotonic stimulation in synoviocytes and also regulates production of IL-8 (PubMed:19759329). Together with PKD2, forms mechano- and thermosensitive channels in cilium (PubMed:18695040). Negatively regulates expression of PPARGC1A, UCP1, oxidative metabolism and respiration in adipocytes (By similarity). Regulates expression of chemokines and cytokines related to proinflammatory pathway in adipocytes (By similarity). Together with AQP5, controls regulatory volume decrease in salivary epithelial cells (By similarity). Required for normal development and maintenance of bone and cartilage (PubMed:26249260). {ECO:0000250|UniProtKB:Q9EPK8, ECO:0000269|PubMed:11025659, ECO:0000269|PubMed:12724311, ECO:0000269|PubMed:16293632, ECO:0000269|PubMed:18587396, ECO:0000269|PubMed:18695040, ECO:0000269|PubMed:18826956, ECO:0000269|PubMed:19759329, ECO:0000269|PubMed:20037586, ECO:0000269|PubMed:21964574, ECO:0000269|PubMed:25256292, ECO:0000269|PubMed:26249260}.; FUNCTION: Isoform 2: Lacks channel activity, due to impaired oligomerization and intracellular retention. {ECO:0000269|PubMed:16293632}.; FUNCTION: Isoform 6: Lacks channel activity, due to impaired oligomerization and intracellular retention. {ECO:0000269|PubMed:16293632}.;

Disease

DISEASE: Brachyolmia 3 (BCYM3) [MIM:113500]: A form of brachyolmia, a clinically and genetically heterogeneous skeletal dysplasia primarily affecting the spine and characterized by a short trunk, short stature, and platyspondyly. BCYM3 is an autosomal dominant form with severe scoliosis with or without kyphosis, and flattened irregular cervical vertebrae. {ECO:0000269|PubMed:18587396}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Spondylometaphyseal dysplasia Kozlowski type (SMDK) [MIM:184252]: A form of spondylometaphyseal dysplasia, a group of short stature disorders distinguished by abnormalities in the vertebrae and the metaphyses of the tubular bones. It is characterized by postnatal dwarfism, significant scoliosis and mild metaphyseal abnormalities in the pelvis. The vertebrae exhibit platyspondyly and overfaced pedicles. {ECO:0000269|PubMed:19232556, ECO:0000269|PubMed:20577006, ECO:0000269|PubMed:22702953}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Metatropic dysplasia (MTD) [MIM:156530]: A severe spondyloepimetaphyseal dysplasia characterized by short limbs with limitation and enlargement of joints and usually severe kyphoscoliosis. Radiologic features include severe platyspondyly, severe metaphyseal enlargement and shortening of long bones. {ECO:0000269|PubMed:19232556, ECO:0000269|PubMed:20425821, ECO:0000269|PubMed:20577006, ECO:0000269|PubMed:22702953, ECO:0000269|PubMed:26249260, ECO:0000269|Ref.6}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Neuronopathy, distal hereditary motor, 8 (HMN8) [MIM:600175]: A clinically variable, neuromuscular disorder characterized by congenital lower motor neuron disorder restricted to the lower part of the body. Clinical manifestations include non-progressive muscular atrophy, thigh muscle atrophy, weak thigh adductors, weak knee and foot extensors, minimal jaw muscle and neck flexor weakness, flexion contractures of knees and pes equinovarus. Tendon reflexes are normal. {ECO:0000269|PubMed:20037588, ECO:0000269|PubMed:22526352, ECO:0000269|PubMed:22702953}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Charcot-Marie-Tooth disease 2C (CMT2C) [MIM:606071]: An axonal form of Charcot-Marie-Tooth disease, a disorder of the peripheral nervous system, characterized by progressive weakness and atrophy, initially of the peroneal muscles and later of the distal muscles of the arms. Charcot-Marie-Tooth disease is classified in two main groups on the basis of electrophysiologic properties and histopathology: primary peripheral demyelinating neuropathies (designated CMT1 when they are dominantly inherited) and primary peripheral axonal neuropathies (CMT2). Neuropathies of the CMT2 group are characterized by signs of axonal degeneration in the absence of obvious myelin alterations, normal or slightly reduced nerve conduction velocities, and progressive distal muscle weakness and atrophy. {ECO:0000269|PubMed:20037586, ECO:0000269|PubMed:20037587, ECO:0000269|PubMed:20037588, ECO:0000269|PubMed:21115951, ECO:0000269|PubMed:21288981, ECO:0000269|PubMed:22702953, ECO:0000269|PubMed:25256292}.
