  • 11 ankyrin repeats
  • four transmembrane domains within the N-terminal region
    CATEGORY signaling
    SUBCELLULAR LOCALIZATION     plasma membrane
  • interacts with the microtubule and actin cytoskeleton
  • basic FUNCTION
  • key feature of the neurotrophin signaling, shown to be critical for neuronal survival under pathologic settings
  • plays an important role in NF-kappaB signaling elicited by brain-derived neurotrophic factor (BDNF)
  • important for the growth of dendritic arbors and spine stability during an activity- and BDNF-dependent period of development
  • key modulator of the activity of microtubule-regulating proteins known to actively regulate neuronal morphogenesis and suggest a mechanism by which it contributes to control neuronal development
  • scaffold protein that has important implications in neurotrophin signalling, modulates the development and maturation of axons and dendrites
  • modulation of its levels can regulate basal synaptic strength in a specific manner in hippocampal neurons
  • serves as a unique downstream adaptor protein of Trk receptor tyrosine kinases
  • major factor that links neurotrophin signaling to NF-kappaB
  • interaction with SEPT5 suggests a possible role as a functional link between neurotrophin receptors and septins to mediate neurotrophin-induced intracellular signaling events, such as neurite outgrowth and cytoskeletal remodeling
  • can be potentially regulated by neuronal activity and calpain action to influence synaptic function
  • required for neuronal differentiation and survival, and its expression levels modulate synaptic plasticity
  • is not essential for basal synaptic transmission and various forms of short-term plasticity, but instead plays a novel role in the mechanisms regulating the recovery of synaptic strength in GABAergic synapses
  • is likely a key player in organizing the signaling complex to transduce the extracellular stimuli to cellular responses during dendrite development
  • was required for optimal calcium signaling
  • acts as a major signaling platform in organizing the signaling complex to regulate various cellular responses in the nervous and vascular systems
  • role of ARMS/Kidins220 as a signaling platform to regulate tumor cell proliferation in response to the extracellular stimuli
  • acts as a signaling platform at the plasma membrane and is implicated in a multitude of neuronal functions, including the control of neuronal activity
    a component
    small molecule
  • transmembrane substrate of tropomyosin receptor kinase B (TRKB)
  • intreacting with Septin 5 (SEPT5)
  • integral membrane protein that was initially identified as a substrate for protein kinase D, a kinase we have found to regulate its intracellular traffic in neurons
  • is rapidly cleaved by calpain during excitotoxicity, a form of neuronal death associated to phosphatases (PPs) activation
  • downstream target of neurotrophin and ephrin receptors, in dendrite development
  • association of NMDARs with KIDINS220 and the participation of this protein in neuronal survival and death pathways
  • KIDINS220 stability and cleavage by calpain is under the control of GSK3B and PP1 activities
  • is a substrate for GSK3B and is likely phosphorylated by this kinase in AD brain, as it has been demonstrated for MAPT
  • is required for TCR-induced sustained, but not transient, Erk activation
  • is a novel TCR-interacting protein that couples BRAF to the TCR
  • transmembrane protein playing a crucial role in neuronal and cardiovascular development
  • downstream target of neurotrophin receptors and interacts with several signalling and trafficking factors
