Summaries for KCNIP1 Gene

Entrez Gene Summary for KCNIP1 Gene

  • This gene encodes a member of the family of cytosolic voltage-gated potassium (Kv) channel-interacting proteins (KCNIPs), which belong to the neuronal calcium sensor (NCS) family of the calcium binding EF-hand proteins. They associate with Kv4 alpha subunits to form native Kv4 channel complexes. The encoded protein may regulate rapidly inactivating (A-type) currents, and hence neuronal membrane excitability, in response to changes in the concentration of intracellular calcium. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, May 2013]

GeneCards Summary for KCNIP1 Gene

KCNIP1 (Kv Channel Interacting Protein 1) is a Protein Coding gene. GO annotations related to this gene include calcium ion binding and protein N-terminus binding. An important paralog of this gene is KCNIP3.

UniProtKB/Swiss-Prot for KCNIP1 Gene

  • Regulatory subunit of Kv4/D (Shal)-type voltage-gated rapidly inactivating A-type potassium channels. Regulates channel density, inactivation kinetics and rate of recovery from inactivation in a calcium-dependent and isoform-specific manner. In vitro, modulates KCND1/Kv4.1 and KCND2/Kv4.2 currents. Increases the presence of KCND2 at the cell surface.

Tocris Summary for KCNIP1 Gene

  • Voltage-gated potassium channels (KV) belong to the 6-TM family of potassium channel that also comprises the Ca2+-activated Slo (actually 7-TM) and the Ca2+-activated SK subfamilies. The pore-forming alpha-subunits contain a single pore-forming region and combine to form tetramers. Heteromeric channels can be formed within subfamilies e.g. KV1.1 with KV1.2 and KCNQ2 with KCNQ3.
