General protein information |
|
Gene Type | protein-coding |
Organism | Homo sapiens(human) |
Genome | |
Summary | The protein encoded by this gene belongs to the family of potassium channel proteins containing two pore-forming P domains. This channel is an open rectifier which primarily passes outward current under physiological K+ concentrations. This gene is activated at alkaline pH. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2008]. |

This sequence is a reference standard in the RefSeqGene project. On May 31, 2019 this sequence version replaced NM_001135111.1. Transcript Variant: This variant (2) contains an additional exon at the 3' end compared to transcript variant 1. This results in a frame-shift and a shorter isoform (2) with a distinct C-terminus compared to isoform 1.
