    motifs/domains
  • an N terminal band 3 binding domain made of 24 tandem subunits of 33 amino-acids (the SW16/Ank repeat)
  • a spectrin binding domain a
  • a regulatory domain with alternatively spliced isoforms
  • a ZU5 domain
  • a death domain
  • Obscurin/Titin-Binding-related Domain (OTBD), a muscle-specific insert of the C-terminal domain which is highly conserved among ankyrin genes, that confer ankyrins with a gain of function in vertebrates, bringing further consolidation and resilience of the linkage between sarcomeres and sarcolemma

    basic FUNCTION
  • plays a role in activities such as cell motility, activation, proliferation, contact, and the maintenance of specialized membrane domains
  • axonal initial segment and nodes of Ranvier of neurons in the central and peripheral nervous systems
  • ankyrin-G is required for transport of CNG channels to the plasma membrane of rod outer segments and is required for rod outer segments morphogenesis
  • ankyrin-G plays role(s) in either assembly and/or maintenance of rod outer segments
  • restricts ion channel diffusion at the axonal initial segment before the establishment of the diffusion barrier
  • ANK3-dependent subventricular zone (SVZ) niche assembly is required for the continued production of new neurons
  • involved in neuronal development and signaling
  • plays a role in intellectual functioning
  • role for ANK3 in modulating the biophysical properties of KCNA1, implicated in renal magnesium handling
  • functions as an adaptor to link Nav channels to KIF5B during axonal transport before anchoring them to the axon initial segment (AIS) and nodes of Ranvier

    INTERACTION
    DNA

    small molecule
    protein
  • interacting with SCN2A1
  • binds to the cytoplasmic domain of CDH1 at a conserved site distinct from that of CTNNB
  • binds to N-cadherin and probably other type 1 classical cadherins (with cadherin partners thus could direct formation of a variety of specialized membrane domains at sites of cell-cell contact, ranging from synapses in the nervous system to inter-calated discs in cardiomyocytes)
  • SODIUM CHANNEL, VOLTAGE-GATED, TYPE V, ALPHA SUBUNIT; SCN5A
  • Cyclic nucleotide–gated (CNG) channels
  • SPTBN4 is recruited to axon initial segments and nodes of Ranvier by ANK3
  • ANK3 expression is controlled by FOXJ1, a transcriptional regulator of multicilia formation
  • CD44 of control chondrocytes was found to interact and co-immunoprecipitate with both the 65- and 130-kDa isoforms of ANK3
  • ANK3 was identified as a binding partner of KCNA1 and was enriched in isolated distal convoluted tubules as compared to whole kidney
  • KIF5B directly binds to ankyrin-G (ANK3) to transport Nav channels into axons
  • constitutive binding of SCN10A with ANK3 could contribute to the pathological aspects of illnesses where SCN10A is ectopically expressed in CNS neurons
