CC -!- FUNCTION: Component of a heteromeric calcium-permeable ion channel
CC formed by PKD1 and PKD2 that is activated by interaction between PKD1
CC and a Wnt family member, such as WNT3A and WNT9B. Can also form a
CC functional, homotetrameric ion channel (PubMed:27214281). Functions as
CC a cation channel involved in fluid-flow mechanosensation by the primary
CC cilium in renal epithelium (PubMed:12514735, PubMed:18695040,
CC PubMed:27760766, PubMed:31048699). Functions as outward-rectifying K(+)
CC channel, but is also permeable to Ca(2+), and to a much lesser degree
CC also to Na(+) (PubMed:27760766). May contribute to the release of
CC Ca(2+) stores from the endoplasmic reticulum (By similarity). Together
CC with TRPV4, forms mechano- and thermosensitive channels in cilium
CC (PubMed:18695040). PKD1 and PKD2 may function through a common
CC signaling pathway that is necessary to maintain the normal,
CC differentiated state of renal tubule cells (PubMed:9568711,
CC PubMed:10615132). Acts as a regulator of cilium length, together with
CC PKD1. The dynamic control of cilium length is essential in the
CC regulation of mechanotransductive signaling. The cilium length response
CC creates a negative feedback loop whereby fluid shear-mediated
CC deflection of the primary cilium, which decreases intracellular cAMP,
CC leads to cilium shortening and thus decreases flow-induced signaling
CC (PubMed:20096584). Also involved in left-right axis specification via
CC its role in sensing nodal flow; forms a complex with PKD1L1 in cilia to
CC facilitate flow detection in left-right patterning (PubMed:21307093,
CC PubMed:22983710). Detection of asymmetric nodal flow gives rise to a
CC Ca(2+) signal that is required for normal, asymmetric expression of
CC genes involved in the specification of body left-right laterality
CC (PubMed:12062060, PubMed:21307093, PubMed:22983710).

CC -!- ACTIVITY REGULATION: Channel activity is regulated by phosphorylation
CC (By similarity). The channel is activated by increased cytoplasmic
CC Ca(2+) (in the uM range) and by membrane depolarization
CC (PubMed:27760766). {ECO:0000250|UniProtKB:Q13563,
CC ECO:0000269|PubMed:27760766}.
CC -!- SUBUNIT: Component of the heterotetrameric polycystin channel complex
CC with PKD1; the tetramer contains one PKD1 chain and three PKD2 chains
CC (By similarity). Interaction with PKD1 is required for ciliary
CC localization (PubMed:25405894). Homotetramer (By similarity). Isoform 1
CC interacts with PKD1 while isoform 3 does not (PubMed:16192288).
CC Interacts with PKD1L1 (PubMed:21307093, PubMed:22983710). PKD1 requires
CC the presence of PKD2 for stable expression (PubMed:16192288). Interacts
CC with CD2AP (PubMed:10913159). Interacts with HAX1 (PubMed:10760273).
CC Interacts with NEK8 (PubMed:18235101). Part of a complex containing
CC AKAP5, ADCY5, ADCY6 and PDE4C (PubMed:21670265). Interacts (via C-
CC terminus) with TRPV4 (via C-terminus) (PubMed:18695040). Interacts (via
CC C-terminal acidic region) with PACS1 and PACS2; these interactions
CC retain the protein in the endoplasmic reticulum and prevent trafficking
CC to the cell membrane (PubMed:15692563). Interacts with TMEM33

CC basolateral membranes and basal cytoplasmic vesicles (PubMed:9568711,
CC PubMed:10770959). Retained in the endoplasmic reticulum by interaction
CC with PACS1 and PACS2. Cilium localization requires GANAB (By

CC -!- TISSUE SPECIFICITY: Detected in kidney epithelium (at protein level)
CC (PubMed:9568711, PubMed:10770959, PubMed:11854751). Highly expressed on
CC basolateral membranes in distal convoluted tubules and medullary thick
CC ascending limbs of Henle (PubMed:9568711). Detected at much lower
CC levels in cortical and medullary collecting tubules, and not detected
CC in the glomerular tuft, in thin limbs of Henle, interstitium and blood
CC vessels (at protein level) (PubMed:9568711). Expressed in mesenchymally
CC derived structures in the developing embryo at day 12.5. Isoform 1 is
CC predominantly expressed in kidney at all developmental stages with high
CC levels also detected in lung. Isoform 3 shows highest expression in
CC brain with lower expression in kidney and lung, low levels in thymus
CC and is hardly detectable in liver. {ECO:0000269|PubMed:10770959,
CC ECO:0000269|PubMed:11854751, ECO:0000269|PubMed:16192288,

CC ECO:0000269|PubMed:9716661}.
CC -!- DEVELOPMENTAL STAGE: Ubiquitous in embryos at the early somite stage.
CC {ECO:0000269|PubMed:22983710}.
CC -!- DOMAIN: The C-terminal coiled-coil domain is involved in
CC oligomerization and the interaction with PKD1. The isolated coiled-coil
CC domain forms a homotrimer in vitro; the homotrimer interacts with a
CC single PKD1 chain. The coiled-coil domain binds calcium and undergoes a
CC calcium-induced conformation change (in vitro).
CC {ECO:0000250|UniProtKB:Q13563}.
CC -!- PTM: N-glycosylated (PubMed:11854751). The four subunits in a tetramer
CC probably differ in the extent of glycosylation; simultaneous
CC glycosylation of all experimentally validated sites would probably
CC create steric hindrance (By similarity). {ECO:0000250|UniProtKB:Q13563,
CC ECO:0000269|PubMed:11854751}.
CC -!- PTM: Phosphorylated (PubMed:16551655). Phosphorylation is important for
CC protein function; a mutant that lacks the N-terminal phosphorylation
CC sites cannot complement a zebrafish pkd2-deficient mutant. PKD-mediated
CC phosphorylation at the C-terminus regulates its function in the release
CC of Ca(2+) stores from the endoplasmic reticulum. PKA-mediated
CC phosphorylation at a C-terminal site strongly increases the open
CC probability of the channel, but does not increase single channel
CC conductance. {ECO:0000250|UniProtKB:Q13563,
CC ECO:0000269|PubMed:16551655}.
CC -!- DISRUPTION PHENOTYPE: Complete embryonic lethality, with most embryos
CC surviving up to about 16.5 dpc (PubMed:9568711, PubMed:10615132,
CC PubMed:12062060). Embryos lacking Pkd2 develop normally up to 13.5 dpc,
CC but after that about half of them display total body edema and focal
CC hemorrhages (PubMed:10615132). Mutant embryos display defects in left-
CC right laterality, including abnormal heart looping (PubMed:12062060).
CC After 13.5 dpc, all embryos display defects in heart development, with
CC defective formation of the interventricular septum (PubMed:10615132,
CC PubMed:12062060). Besides, many display defective formation of the
CC atrial septum and pericardial effusions (PubMed:10615132). After 14.5
CC dpc, the embryos display progressive cystic dilatation of pancreatic
CC ducts (PubMed:10615132). After 15.5 dpc, they display progressive
CC kidney cyst formation (PubMed:10615132). In contrast, liver development
CC is normal, without any cyst formation (PubMed:10615132). Heterozygous
CC mice with one null allele and one instable allele that leads to somatic
CC loss of Pkd2 expression due to intragenic recombination all display
CC bilateral renal cysts at an age of about 11 weeks (PubMed:9568711).
CC These cysts cover 25-75% of the cut surface area of each kidney
CC (PubMed:9568711). Progressive cyst formation leads eventually to renal
CC failure and shortened lifespan (PubMed:10615132). Besides, these mice
CC all display liver cysts and half of them display also bile duct
CC proliferation (PubMed:9568711). About half of the heterozygous mice
CC with one null allele and one instable allele that leads to somatic loss
CC of Pkd2 expression due to intragenic recombination display visible
CC pancreas cysts at an age of three months (PubMed:10615132). Mice
CC homozygous for an instable allele that leads to somatic loss of Pkd2
CC expression due to intragenic recombination develop renal cysts that
CC arise from cells that have lost Pkd2 expression (PubMed:9568711).
CC Heterozygous mice that bear one null allele also have a reduced
CC lifespan, but this is not due to kidney failure (PubMed:10615132).
