UniProt Protein Function: | KCNIP2: Regulatory subunit of Kv4/D (Shal)-type voltage-gated rapidly inactivating A-type potassium channels. Probably modulates channels density, inactivation kinetics and rate of recovery from inactivation in a calcium-dependent and isoform-specific manner. In vitro, modulates KCND2/Kv4.2 and KCND3/Kv4.3 currents. Involved in KCND2 and KCND3 trafficking to the cell surface. Belongs to the recoverin family. 9 isoforms of the human protein are produced by alternative splicing.Chromosomal Location of Human Ortholog: 10q24Cellular Component: voltage-gated potassium channel complex; cytoplasmMolecular Function: identical protein binding; protein binding; potassium channel regulator activity; protein N-terminus binding; calcium ion binding; ER retention sequence binding; A-type (transient outward) potassium channel activityBiological Process: synaptic transmission; muscle contraction; clustering of voltage-gated potassium channels; detection of calcium ion; signal transduction; regulation of heart contraction; potassium ion transport |

NCBI Summary: | This gene encodes a member of the family of voltage-gated potassium (Kv) channel-interacting proteins (KCNIPs), which belongs to the recoverin branch of the EF-hand superfamily. Members of the KCNIP family are small calcium binding proteins. They all have EF-hand-like domains, and differ from each other in the N-terminus. They are integral subunit components of native Kv4 channel complexes. They may regulate A-type currents, and hence neuronal excitability, in response to changes in intracellular calcium. Multiple alternatively spliced transcript variants encoding distinct isoforms have been identified from this gene. [provided by RefSeq, Jul 2008] |
