Function

Aquaporins form homotetrameric transmembrane channels, with each monomer independently mediating water transport across the plasma membrane along its osmotic gradient. Plays an important role in fluid secretion in salivary glands. Required for TRPV4 activation by hypotonicity.

Biological Context

Subcellular Location: Apical cell membrane (Multi-pass membrane protein); Cell membrane (Multi-pass membrane protein); Cytoplasmic vesicle membrane (Multi-pass membrane protein)
Tissue Specificity: Detected in skin eccrine sweat glands, at the apical cell membrane and at intercellular canaliculi (at protein level)
Disease Association: Keratoderma, palmoplantar, Bothnian type (PPKB) : A dermatological disorder characterized by diffuse non-epidermolytic hyperkeratosis of the skin of palms and soles. PPKB is frequently complicated by fungal infections. [The disease is caused by variants affecting the gene represented in this entry]

Protein Biology

Function

Aquaporins form homotetrameric transmembrane channels, with each monomer independently mediating water transport across the plasma membrane along its osmotic gradient (PubMed:18768791, PubMed:8621489). Plays an important role in fluid secretion in salivary glands (By similarity). Required for TRPV4 activation by hypotonicity. Together with TRPV4, controls regulatory volume decrease in salivary epithelial cells (PubMed:16571723). Seems to play a redundant role in water transport in the eye, lung and in sweat glands (By similarity)

Subcellular Location

Apical cell membrane (Multi-pass membrane protein); Cell membrane (Multi-pass membrane protein); Cytoplasmic vesicle membrane (Multi-pass membrane protein)

Disease Association

Keratoderma, palmoplantar, Bothnian type (PPKB) : A dermatological disorder characterized by diffuse non-epidermolytic hyperkeratosis of the skin of palms and soles.

Tissue Specificity

Subunit

Homotetramer; each monomer provides an independent water pore (PubMed:18768791, PubMed:26569106). Interacts with TRPV4; the interaction is probably indirect and regulates TRPV4 activation by hypotonicity
