26509711 IRBIT forms signaling complexes with PIPKIalpha and NBCe1-B, whose activity is regulated by PI(4,5)P2.
25237103 Formation of the Ribonucleotide reductase-IRBIT complex is regulated through phosphorylation of IRBIT, and ablation of IRBIT expression in HeLa cells causes imbalanced dNTP pools and altered cell cycle progression.
24518248 IRBIT is a master regulator of ion channels and ion transporters. (Review)
24489003 HIV-1 Tat modulates IRBIT expression in neuron cells
23769829 IRBIT plays an important role in intracellular pH regulation, mediated by NHE3, and further regulated by SPAK.
23431199 relationships between the WNK/SPAK and IRBIT/PP1 sites in the regulation of Na+-HCO3- cotransporters
22826361 conclude that AHCYL1 expression is associated with ovarian carcinogenesis as an oncogene in chickens, whereas it plays the role of tumor suppressor in human EOC, suggesting a paradoxical function of AHCYL1 in ovarian carcinogenesis
22012331 A NBCe1-B construct that lacks amino acid residues 2-16 of the amino-terminus is fully autoinhibited, but cannot be stimulated by IRBIT, indicating that autoinhibitory and IRBIT-binding determinants within the cytosolic amino-terminus are not identical.
21956116 HIV-1 Tat modulates IRBIT expression in neuron cells
21317537 IRBIT opposes the effects of WNKs and SPAK by recruiting PP1 to the complex to dephosphorylate CFTR and NBCe1-B, restoring their cell surface expression, in addition to stimulating their activities
21242704 Both IRBIT (inositol 1,4,5-trisphosphate receptor-binding protein) and WNK [with no lysine (K)] kinase have been implicated as additional HCO(3)(-) secretory controllers.
20584908 IRBIT is critically involved in mediating activation of NHE3 by ANG II via a Ca(2+)/calmodulin-dependent protein kinases II-dependent pathway.
19220705 An IRBIT homologue, Long-IRBIT, demonstrates only weak binding ability to inositol 1,4,5-trisphosphate receptor because of an inhibitory effect of its LISN domain, a Long-IRBIT specific N-terminal appendage.
16769890 regulation through IRBIT enables NBC1 variants to have different physiological roles
