Entrez Gene summary for KCNJ5:
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. It may associate with two other G-protein-activated potassium channels to form a
heteromultimeric pore-forming complex. (provided by RefSeq, Jul 2008)

UniProtKB/Swiss-Prot: IRK5_HUMAN, P48544
Function: This potassium channel is controlled by G proteins. Inward rectifier potassium channels are characterized by
a greater tendency to allow potassium to flow into the cell rather than out of it. Their voltage dependence is
regulated by the concentration of extracellular potassium; as external potassium is raised, the voltage range of the
channel opening shifts to more positive voltages. The inward rectification is mainly due to the blockage of outward
current by internal magnesium. Can be blocked by external barium

summary for KCNJ5:
The inward-rectifier potassium channel family (also known as 2-TM channels) include the strong
inward-rectifier channels (KIR2.x), the G-protein-activated inward-rectifier channels (KIR3.x) and the
ATP-sensitive channels (KIR6.x, which combine with sulphonylurea receptors (SUR)). Structurally, the
pore-forming subunit of KIR channels is the alpha-subunit. It contains a single pore domain between two
membrane spanning regions. Four alpha-subunits combine to form a tetramer, with the pore domain of each
subunit contributing to the structure of the central pore. Heteromeric channels can also be formed within
subfamilies, e.g. KIR3.2 with KIR3.3.

    UniProtKB/Swiss-Prot: IRK5_HUMAN, P48544
  • Defects in KCNJ5 are the cause of long QT syndrome type 13 (LQT13) [MIM:613485]. It is a heart disorder
  • characterized by a prolonged QT interval on the ECG and polymorphic ventricular arrhythmias. They cause syncope and
    sudden death in response to excercise or emotional stress, and can present with a sentinel event of sudden cardiac
    death in infancy
  • Defects in KCNJ5 are the cause of familial hyperaldosteronism type 3 (FH3) [MIM:613677]. A form of
  • hyperaldosteronism characterized by hypertension secondary to massive adrenal mineralocorticoid production. Like
    patients with familial hyperaldosteronism type 1 (glucocorticoid-remediable aldosteronism), patients with FH3 present
    with childhood hypertension, elevated aldosteronism levels, and high levels of the hybrid steroids 18-oxocortisol and
    18-hydroxycortisol. However, hypertension and aldosteronism are not reversed by administration of exogenous
    glucocorticoids and patients require adrenalectomy to control hypertension
  • Note=Somatic mutations in KCNJ5 have been found in aldosterone-producing adrenal adenomas and can be
  • responsible for aldosteronism associated with cell autonomous proliferation. These are typically solitary, well
    circumscribed tumors diagnosed between ages 30 and 70. They come to medical attention due to new or worsening
    hypertension, often with hypokalemia. KCNJ5 mutations produce increased sodium conductance and cell depolarization,
    which in adrenal glomerulosa cells produces calcium entry, the signal for aldosterone production and cell
    proliferation
