Four G protein gated inwardly-rectifying potassium ( GIRK ) channel subunits have been identified in mammals: GIRK1, GIRK2, GIRK3, and GIRK4.

GIRK1, GIRK2, and GIRK3 show abundant and overlapping distribution in the central nervous system ( CNS ) while GIRK1 and GIRK4 are found primarily in the heart.

GIRK1 combines with GIRK2 in the CNS and GIRK4 in the atrium to form heterotetramers ; each final heterotetramer contains two GIRK1 subunits and two GIRK2 or GIRK4 subunits.

GIRK2 subunits can also form homotetramers in the brain, while GIRK4 subunits can form homotetramers in the heart.

People with Down Syndrome have three copies of chromosome 21, resulting in an overexpression of the GIRK2 subunit.

The KCNJ6 gene is located on chromosome 21 and encodes for the GIRK2 protein subunit of G protein-gated K < sup >+</ sup > channels.

Though GIRK3 subunits are found in the CNS, their role in forming functional ion channels is still unknown.

The G < sub > βγ </ sub >- complex binds directly and specifically to the IKACh channel through interactions with both the GIRK1 and GIRK4 subunits .< ref name =" pmid9478984 "> Once the ion channel is activated, K < sup >+</ sup > ions flow out of the cell and cause it to hyperpolarize.

In GIRK4, the N-terminal residue is His-64 and the C-terminal residue is Leu-268 ; in GIRK1 they are His-57 and Leu-262, respectively.

IKACh is composed of two homologous GIRK channel subunits: GIRK1 and GIRK4.
