关于 KCNQ4

Cytogenetic location: 1p34.2 Genomic coordinates (GRCh38): 1:40,783,787-40,840,452 (from NCBI)

This gene has 4 transcripts (splice variants), 199 orthologues, 31 paralogues and is associated with 2 phenotypes. Ubiquitous expression in endometrium (RPKM 1.8), prostate (RPKM 1.3) and 24 other tissues.

功能概要

由该基因编码的蛋白质形成钾通道,该通道被认为在调节神经元兴奋性方面发挥关键作用,特别是在耳蜗的感觉细胞中。该通道产生的电流被 M1 毒蕈碱性乙酰胆碱受体抑制,并被新型抗惊厥药物瑞替加滨激活。编码的蛋白质可以形成与 KCNQ3 基因编码的蛋白质相关的同源多聚体钾通道或可能形成异源多聚体通道。该基因的缺陷是导致 2 型非综合征性感音神经性耳聋 (DFNA2) 的原因,这是一种常染色体显性遗传的进行性听力损失形式。已发现该基因的两个转录本变体编码不同的亚型。[RefSeq 提供,2008 年 7 月]

The protein encoded by this gene forms a Potassium Channel that is thought to play a critical role in the regulation of neuronal excitability, particularly in sensory cells of the cochlea. The current generated by this channel is inhibited by M1 muscarinic acetylcholine receptors and activated by retigabine, a novel anti-convulsant drug. The encoded protein can form a homomultimeric Potassium Channel or possibly a heteromultimeric channel in association with the protein encoded by the KCNQ3 gene. Defects in this gene are a cause of nonsyndromic sensorineural deafness type 2 (DFNA2), an autosomal dominant form of progressive hearing loss. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
