The cyclin-dependent kinase activator, Spy1A, is targeted for degradation by the ubiquitin ligase NEDD4.
Spy1A is a cyclin-like protein required for progression through the G(1)/S phase of the cell cycle. Elevated Spy1A protein levels have been implicated in tumorigenesis and are attributed to overriding the DNA damage response and enhancing cell proliferation. Understanding how Spy1A is produced and degraded is essential in resolving how it contributes to normal and abnormal growth processes. Her...
متن کاملCyclin-Dependent Kinases: CAK-handed kinase activation
A protein kinase that activates cyclin-dependent kinases has been identified as a related catalytic subunit in association with a novel cyclin regulatory subunit--it is itself a cyclin-dependent kinase.
متن کاملNeuronal morphogenesis is regulated by the interplay between cyclin-dependent kinase 5 and the ubiquitin ligase mind bomb 1.
Neuronal communication requires the coordinated assembly of polarized structures including axons, dendrites, and synapses. Here, we report the identification of a ubiquitin ligase mind bomb 1 (Mib1) in the postsynaptic density and the characterization of its role in neuronal morphogenesis. Expression of Mib1 inhibits neurite outgrowth in cell culture and its gene deletion enhances synaptic grow...
متن کاملPirh2 promotes ubiquitin-dependent degradation of the cyclin-dependent kinase inhibitor p27Kip1.
The cyclin-dependent kinase inhibitor p27(Kip1) is degraded in late G(1) phase by the ubiquitin-proteasome pathway, allowing cells to enter S phase. Due to accelerated degradation of p27(Kip1), various human cancers express low levels of p27(Kip1) associated with poor prognosis. S-phase kinase-associated protein 2, the F-box protein component of an SCF ubiquitin ligase complex, is implicated in...
متن کاملActivation of cyclin-dependent kinase 5 mediates orofacial mechanical hyperalgesia
BACKGROUND Cyclin-dependent kinase 5 (Cdk5) is a unique member of the serine/threonine kinase family. This kinase plays an important role in neuronal development, and deregulation of its activity leads to neurodegenerative disorders. Cdk5 also serves an important function in the regulation of nociceptive signaling. Our previous studies revealed that the expression of Cdk5 and its activator, p35...
