Also known as KCHIP1
Summary
KCNIP1 (potassium voltage-gated channel interacting protein 1, HGNC:15521) is a protein-coding gene on chromosome 5q35.1, encoding A-type potassium channel modulatory protein KCNIP1 (Q9NZI2). Regulatory subunit of Kv4/D (Shal)-type voltage-gated rapidly inactivating A-type potassium channels.
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.

Literature-anchored findings (GeneRIF, showing 12)
- Data show that KChIP1, KChIP2.1, and KChIP2.2 could form homo- as well as hetero-oligomers, and that this oligomerization did not perturb their interaction with Kv4.2 potassium channel. (PMID:15358149)
- X-ray crystallographic and small-angle X-ray scattering data that show that the KChIP1-Kv4.3 N-terminal cytoplasmic domain complex is a cross-shaped octamer bearing two principal interaction sites. (PMID:17057713)
- These results reveal a new role for KChIP3 in the regulation of calcium regulated secretion and also suggest that the functions of each of the KChIPs may be more specialized than previously appreciated. (PMID:18393943)
- EF-hands 3 and 4 of KChIP1 are functionally involved in a specific association with PS on the membrane (PMID:19550036)
- our findings suggest that KChIP1 interacts with Kv4.3 in interneurons at the stratum lacunosum-moleculare/radiatum junction (PMID:21129448)
- Protein aggregation due to nsSNP resulting in P56S VABP protein is associated with amyotrophic lateral sclerosis (PMID:24681403)
- V234I-VAPB induces ubiquitin aggregation followed by cell death; proposed that V234I-VAPB exhibits the characteristics of amyotrophic lateral sclerosis in spite of not having the typical aggregation property of different mutations in various neurodegenerative diseases (PMID:24792378)
- KCNIP1 from copy number variations study might function as a type 2 diabetes susceptibility gene whose dysregulation alters insulin production. (PMID:24886904)
- These studies showed that a common copy number variation in KCNIP1 gene is a genetic predictor of atrial fibrillation risk possibly pointing to a functional pathway. (PMID:26831368)
- Study shows that the VAPB-PTPIP51 tethers regulate autophagy and demonstrates that overexpression of VAPB or PTPIP51 to tighten endoplasmic reticulum-mitochondria contacts impairs, whereas small interfering RNA-mediated loss of VAPB or PTPIP51 to loosen contacts stimulates, autophagosome formation. (PMID:28132811)
- the current study provides evidence that genetic variants of Kv accessory proteins may contribute to the susceptibility of Attention-deficit/hyperactivity disorder. (PMID:29176790)
- This is the first copy number variation association study of the KCNIP1 gene in Chinese population, and these data indicated that KCNIP1 might function as a type 2 diabetes-susceptibility gene whose dysregulation alters insulin production. (PMID:29491224)

Function. 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.
Subunit / interactions. Component of heteromultimeric potassium channels. Identified in potassium channel complexes containing KCND1, KCND2, KCND3, KCNIP1, KCNIP2, KCNIP3, KCNIP4, DPP6 and DPP10. Part of a heterooctamer composed of the tetrameric channel and four KCNIP1 chains. Probably part of a complex consisting of KCNIP1, KCNIP2 isoform 3 and KCND2. Self-associates to form homodimers and homotetramers. Interacts with KCNIP2 isoform 3 in a calcium-dependent manner. Interacts with Naja atra venom CTX3. Interacts with KCND2; this interaction mediates the capture of both the N- and C-terminus of KCND2, thus preventing KCND2 N-type inactivation and modulates the channel gating kinetics. Interacts with KCND3; each KCNIP1 monomer interacts with two adjacent KCND3 subunits, through both the N-terminal inactivation ball of a KCND3 subunit and a C-terminal helix from the adjacent KCND3 subunit, clamping them together; this interaction stabilizes the tetrameric form and modulates the channel gating kinetics namely channel activation and inactivation kinetics and rate of recovery from inactivation.
Subcellular location. Cell membrane. Cytoplasm. Cell projection. Dendrite.
Tissue specificity. Isoform 1 and isoform 2 are expressed in brain and kidney. Isoform 1 is also expressed in liver, pancreas, skeletal muscle, small intestine and testis. Isoform 2 is also expressed in lung, pancreas, leukocytes, prostate and thymus.
Similarity. Belongs to the recoverin family.
