Calsenilin

Calsenilin is a is_associated_with::protein that in humans is encoded by the KCNIP3 is_associated_with::gene.

Function
This gene encodes a member of the family of voltage-gated potassium (Kv) channel-interacting proteins, which belong to the neuronal calcium sensor family of proteins. Members of this family are small calcium binding proteins containing is_associated_with::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 is_associated_with::presenilins. is_associated_with::Alternatively spliced transcript variants encoding different isoforms have been described.

Interactions
Calsenilin has been shown to interact with is_associated_with::PSEN1 and is_associated_with::PSEN2.
