Reference | [1] Proteomic analyses reveal divergent ubiquitylation site patterns in murine tissues. Wagner SA, Beli P, Weinert BT, Schölz C, Kelstrup CD, Young C, Nielsen ML, Olsen JV, Brakebusch C, Choudhary C. Mol Cell Proteomics. 2012 Dec;11(12):1578-85. [ PMID: 22790023] |
Functional Description | Probably important in the regulation of neuronal excitability. Associates with KCNQ2 to form a potassium channel with essentially identical properties to the channel underlying the native M-current, a slowly activating and deactivating potassium conductance which plays a critical role in determining the subthreshold electrical excitability of neurons as well as the responsiveness to synaptic inputs (By similarity). |
