Research Backgrounds

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. Also activated by heat, 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 (By similarity). 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. Together with PKD2, forms mechano- and thermosensitive channels in cilium. 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.

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. Also activated by phorbol esters. Has the same channel activity as isoform 1, and is activated by the same stimuli.

Lacks channel activity, due to impaired oligomerization and intracellular retention.

Tissue Specificity:

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

Subunit Structure:

Homotetramer (Probable). Self-associates in an isoform-specific manner. Isoform 1 and isoform 5 can oligomerize, but isoform 2, isoform 4 and isoform 6 cannot oligomerize. Interacts with calmodulin. Interacts with Map7 and Src family Tyr protein kinases LYN, SRC, FYN, HCK, LCK and YES (By similarity). Interacts with CTNNB1 (By similarity). The TRPV4 and CTNNB1 complex can interact with CDH1 (By similarity). Interacts with PACSIN1, PACSIN2 and PACSIN3 (via SH3 domain) (By similarity). Part of a complex containing MLC1, AQP4, HEPACAM and ATP1B1. Interacts with ITPR3. Interacts with AQP5; the interaction is probably indirect and regulates TRPV4 activation by hypotonicity (By similarity). Interacts with ANO1 (By similarity). Interacts (via C-terminus) with PKD2 (via C-terminus).

Family&Domains:

The ANK repeat region mediates interaction with Ca(2+)-calmodulin and ATP binding (By similarity). The ANK repeat region mediates interaction with phosphatidylinositol-4,5-bisphosphate and related phosphatidylinositides (PubMed:25256292).

Belongs to the transient receptor (TC 1.A.4) family. TrpV subfamily. TRPV4 sub-subfamily.

Figure 4 LiESWT increased neuronal regeneration, synaptic transmission, and receptor response. The expressions of neuronal endogenous markers (NF, NeuN, and GFAP) and muscarinic receptor (M2 and M3), and purinergic receptor (P2X7) markers were assessed by immunostaining (A–H) and Western blots (I,J). Nuclear DNA was labeled with DAPI (blue). (A–D) The M2 immunostaining was markedly expressed in the UL and SL of the (A) sham group. On the contrary, there was less M2 staining expression in the thinner and defective urothelial mucosa in the UL (yellow arrows) of the (B) OVX group, but the immunostainings in the (C) OVX + SW4 group and the (D) OVX + SW8 group were enhanced. (E–H) Double-labeled analysis of M2 (red, upper panels) and NF (green, lower panels) was distributed in the ML of the (E) sham group. However, the double staining of the (G) OVX + SW4 group and the (H) OVX + SW8 group were widely expressed compared with the (F) OVX group. (I,J) Quantifications of the percentage of neurogenesis-related markers, muscarinic receptors, and purinergic receptors were evaluated by Western blotting. The expressions obviously decreased in the OVX group compared with the sham group. However, the expressions significantly increased in the OVX + SW4 group and OVX + SW8 group compared with the OVX group. Therefore, the LiESWT promoted bladder synaptic transmission, receptor response, and neurogenesis to ameliorate the bladder detrusor contractile response. Nuclear DNA was labeled with DAPI (blue). LiESWT, low-intensity extracorporeal shock wave therapy; OVX + SW4, OHD status for 12 months, followed by once weekly LiESWT for 4 weeks; OVX + SW8, OHD status for 12 months, followed by twice weekly LiESWT for 4 weeks; DAPI, 4′,6-diamidino-2-phenylindole; NF, neurofilament; NeuN, neuronal nuclear antigen and neuron; GFAP, glial fibrillary acidic protein; GAPDH, glyceraldehyde-3-phosphate dehydrogenase; UL, urothelial layer; SL, suburothelial layer.
