= GRIK2
{c}

<GRIK2> is a human <gene> encoding the <GluK2> subunit of <kainate receptors>. Older experimental literature commonly calls this subunit GluR6. The symbol refers to the <gene>; the encoded subunit assembles with other subunits into a ligand-gated <ion channel>.<GRIK2 in NCBI Gene>[GeneID2898, official name and RefSeq Summary]{ref}

The subunit is subject to <RNA editing>, and alternatively processed transcripts can encode different isoforms. Thus locating one <gene> does not establish that every cell makes one unchanging protein sequence.<GRIK2 in NCBI Gene>[RefSeq Summary and transcript-variant descriptions; editing and isoforms]{ref}

A motivating 1998 experiment removed the corresponding GluR6 subunit in mice and recorded currents at <chemical synapses>. Train-evoked mossy-fibre <kainate receptor> currents were lost, alongside altered responses to kainate.<Altered synaptic physiology and reduced susceptibility to kainate-induced seizures in GluR6-deficient mice by C. Mulle and others>[Abstract; deletion, CA3 physiology and mossy-fibre postsynaptic currents]{ref} Genetic perturbation and direct current measurements connect the subunit to a circuit response more specifically than observing its RNA alone. They do not establish that every human variant has the same consequence as deleting the mouse gene.
