Calsenilin is a protein that in humans is encoded by the KCNIP3 gene. ^{[4] [5] [6]}

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. ^{[7] [8]} 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. In addition, the protein has been shown to transcriptionally repress A20 ( TNFAIP3) expression and thus modulate the anti-inflammatory signaling. ^[9] Alternatively spliced transcript variants encoding different isoforms have been described. ^[6]

Interactions

Calsenilin has been shown to interact with PSEN1 ^{[4] [10]} and PSEN2. ^{[4] [11]}
