This gene has 5 transcripts (splice variants), 202 orthologues, 15 paralogues and is associated with 3 phenotypes. Broad expression in fat (RPKM 16.1), heart (RPKM 14.3) and 20 other tissues.

功能概要

钾通道存在于大多数哺乳动物细胞中,它们参与广泛的生理反应。该基因编码的蛋白是一种完整的膜蛋白和内向整流型钾通道。编码的蛋白质更倾向于让钾流入细胞而不是流出细胞,由 G 蛋白控制。该基因的缺陷可能是 J 波综合征和婴儿猝死综合征 (SIDS) 的原因。[RefSeq 提供,2012 年 5 月]

Potassium channels are present in most mammalian cells, where they participate in a wide range of physiologic responses. The protein encoded by this gene is an integral membrane protein and inward-rectifier type Potassium Channel. The encoded protein, which has a greater tendency to allow potassium to flow into a cell rather than out of a cell, is controlled by G-proteins. Defects in this gene may be a cause of J-wave syndromes and sudden infant death syndrome (SIDS). [provided by RefSeq, May 2012]
