UniProt Protein Function: | calsenilin: a small calcium-binding protein. Member of the family of voltage-gated potassium (Kv) channel-interacting proteins (KCNIPs), which belong to the recoverin branch of the EF-hand superfamily. Modulates K4 voltage-gated potassium channels. May regulate A-type currents, and hence neuronal excitability, in response to changes in intracellular calcium. Also functions as a calcium-regulated transcriptional repressor, and to interact with presenilins. May play a role in the regulation of PSEN2 proteolytic processing. |

NCBI Summary: | This gene encodes a member of the family of voltage-gated potassium (Kv) channel-interacting proteins, which belong to the recoverin branch of the EF-hand superfamily. Members of this family are small calcium binding proteins containing EF-hand-like domains. They are integral subunit components of native Kv4 channel complexes that may regulate A-type currents, and hence neuronal excitability, in response to changes in intracellular calcium. The encoded protein also functions as a calcium-regulated transcriptional repressor, and interacts with presenilins. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Jul 2008] |
