25599232 The findings of this study suggest that variations in KCNJ3 genes are associated with both mild and severe persistent breast pain after breast cancer surgery.
24392765 For KCNJ3 rs7574878, individuals who were heterozygous or homozygous for the rare G allele (TT versus TG+ GG) had a 48% reduction in the odds of reporting preoperative breast pain.
23368630 we show that Kir3.1, in the absence of trafficking partner subunits, can exit the endoplasmic reticulum (ER) and reach the Golgi (though not the plasma membrane)
23219908 In the dorsal horn of the developing rat, K(ir)3.1 and K(ir)3.2 were expressed at mature levels from birth.
23175530 Conformational changes at the Gbetagamma/Kir3 interface were lost when Kir3.1 subunits were replaced.
21927946 These data suggest that the KCNJ3 gene is genetically associated with schizophrenia in Asian populations and add further evidence to the "channelopathy theory of psychiatric illnesses".
21420934 Kir3.1 channel is involved in the TLR4-mediated signal at an early event by facilitating the recruitment of TLR4 into lipid raft.
21044958 halothane predominantly interferes with Gbetagamma-mediated Kir3 currents, such as those functioning during inhibitory synaptic activity
20512921 The very high abundance of mRNA's encoding GIRK1 together with the presence of GIRK1 protein suggests a pathophysiological role in breast cancer
20468064 Observational study of gene-disease association. (HuGE Navigator)
20110696 We identified several known single nucleotide polymorphisms in KCNJ3 and KCNJ5, but no mutations in either of the genes.
20110696 Observational study of gene-disease association. (HuGE Navigator)
19151997 S385 identified as in vitro phosphorylation site. Mutation of this residue to alanine resulted in reduced sensitivity of Kir3.1* currents to H89 & Forskolin, confirming in vivo role for this novel site of the Kir3.1 channel subunit in regulation by PKA.
19135528 Sar 1 H79G and Rab 1 S25N mutants efficiently blocked the plasma membrane trafficking of the Kir3.1/Kir3.4 complex however they did not block the Gbeta1gamma2/Kir3.1 interaction. Gbeta1-4 can interact with Kir3.1 in the absence of Kir3.4.
18498071 GIRK1 was overexpressed in breast carcinoma suggesting its involvement in proliferation and oncogenesis and its possible use as a putative pharmaceutical target.
16109170 GIRK1 and GIRK2 channels, but not GIRK3 or GIRK4, may may activate signaling pathways in development of lung cancer
15142872 that GIRK channels are important functional effectors of the P2Y(12) receptor in human platelets.

12034888 glutamate residue at the C terminus regulates activity -- implications for Andersen Disease (inward rectifier potassium channel 2; IRK2)
