  • Function

    Non-selective calcium permeant cation channel probably involved in osmotic sensitivity and mechanosensitivity. Activation by exposure to hypotonicity within the physiological range exhibits an outward rectification. Also activated by low pH, citrate and phorbol esters. Increase of intracellular Ca(2+) potentiates currents. Channel activity seems to be regulated by a calmodulin-dependent mechanism with a negative feedback mechanism. Promotes cell-cell junction formation in skin keratinocytes and plays an important role in the formation and/or maintenance of functional intercellular barriers. Acts as a regulator of intracellular Ca(2+) in synoviocytes. 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.
  • Tissue specificity

    Found in the synoviocytes from patients with (RA) and without (CTR) rheumatoid arthritis (at protein level).
  • Involvement in disease

    Scapuloperoneal spinal muscular atrophy
    Spondyloepiphyseal dysplasia Maroteaux type
    Parastremmatic dwarfism
    Digital arthropathy-brachydactyly, familial
  • Sequence similarities

    Belongs to the transient receptor (TC 1.A.4) family. TrpV subfamily. TRPV4 sub-subfamily.
    Contains 3 ANK repeats.
  • Post-translational

    Phosphorylation results in enhancement of its channel function.
  • Cellular localization

    Cell membrane and Cell membrane. Cell junction > adherens junction. Assembly of the putative homotetramer occurs primarily in the endoplasmic reticulum.
