  • attached to the plasma membrane via a N terminal myristoylation anchor cleaved into a C terminal p25 part
  • N-terminal p10 regions, that is a unique prosurvival domain in CDK5R1, essential for normal CDK5/CDK5R1 function in neurons, and loss of the p10 domain results in CDK5/CDK5R1 toxicity and neurodegeneration
  • C-terminal CDK5 activation domains (AD)

    SUBCELLULAR LOCALIZATION     plasma membrane
    basic FUNCTION
  • neuronal specified activator of CDK5
  • maybe involved in cytoskeletal anormalities and neuronal death in the pathogenesis of neurodegenerative diseases such as Alzheimer
  • microtubule-associated protein that modulates microtubule dynamics and microtubules play an important role in the control of CDK5 activation
  • at least one of the activators of CDK5 that is mobilized in the process of cellular senescence, which may provide insight into cancer cell proliferation and future cancer therapeutics
  • CDK5R1, HOPX, FKBP4, SGTA proteins plays a distinct role in the steroid hormone receptor regulatory cycle
  • activators of CDK5, CDK5R1, and CCNI are not required for normal kidney function, but, they play pivotal coordinated roles in maintaining podocyte survival during stress states in disease (pMID: 22262481)
  • CDK5/CDK5R1 is required for motor learning and involved in long-term synaptic plasticity
  • CDK5R1-dependent mechanism in transcriptional regulation that involves the nucleocytoplasmic shuttling of transcription regulators
  • CDK5/CDK5R1 regulates spatial learning and memory, implicating CDK5/CDK5R1 as a therapeutic target in neurological disorders
  • predominance of CCNI mediates the nuclear localization of CDK5, whereas the predominance of CDK5R1 results in a membranous localization of CDK5
  • acts as a mediator of RHO GTPase activity and contributes to the neuroprotection induced by CDK5 RNAi
  • CDK5 and CDK5R1, encoding CDK5 activator p35, have a fundamental role in central nervous system (CNS) development and function, and are involved in the pathogenesis of several neurodegenerative disorders
  • CELLULAR PROCESS cell life, proliferation/growth
    text negative control
    a component
  • heterodimerizing with CDK5, with a resulting hyperphosphorylation of tau, which reduces tau's ability to associate with microtubules
  • SIK2-CDK5R1-PJA2 complex is essential for glucose homeostasis and provides a link between CDK5R1-CDK5 and the AMPK family in excitable cells
    small molecule
  • binding to neuronal CDK5
  • binds directly to alpha/beta-tubulin and microtubules
  • interacting with HSF2 through the promoter (CDK5R1 is the first target gene for HSF2 in cortical development)
  • interacting with RB1 (CDK5R1 is required for the acquisition of the senescent morphology in RB1-induced senescence, which is consistent with our previous finding that CDK5 activity is required in such changes)
  • CDK5 is activated by both CCNI and the noncyclin activator CDK5R1 in terminally differentiated cells such as kidney podocytes and neurons
  • ZNF335 is a new interacting partner of CDK5R1
  • CDK5R1 interacts with ZNF335 and regulates its nucleocytoplasmic trafficking via the nuclear export pathway
  • cell & other
    repressed by cleaved to p25 by Ca2+ calpain
