Summary: Enables enzyme regulator activity. Involved in epithelial fluid transport. Acts upstream of or within several processes, including protein export from nucleus; regulation of mRNA 3'-end processing; and regulation of monoatomic ion transport. Located in cytosol and intracellular membrane-bounded organelle. Is expressed in several structures, including alimentary system; integumental system; nervous system; respiratory system; and sensory organ. Orthologous to human AHCYL1 (adenosylhomocysteinase like 1). [provided by Alliance of Genome Resources, Nov 2024]

Both IRBIT and long-IRBIT bind to and coordinately regulate Cl(-)/HCO3(-) exchanger AE2 activity through modulating the lysosomal degradation of AE2.
Title: Both IRBIT and long-IRBIT bind to and coordinately regulate Cl(-)/HCO(3)(-) exchanger AE2 activity through modulating the lysosomal degradation of AE2.
IRBIT controlled five phosphorylation sites in NBCe1-B that determined both the active conformation of the transporter and its regulation by Cl(-)

NHERF1 mediates ANG II-induced activation of renal NHE3, which requires coordination between IRBIT and the NHERF1 PDZ1 domain in binding and transporting NHE3
Title: The NHERF1 PDZ1 domain and IRBIT interact and mediate the activation of Na+/H+ exchanger 3 by ANG II.
IRBIT forms signaling complexes with PIPKIalpha and NBCe1-B, whose activity is regulated by PI(4,5)P2.

Irbit was sequestered by InsP3 receptors (IP3Rs) in the endoplasmic reticulum
Title: Irbit mediates synergy between ca(2+) and cAMP signaling pathways during epithelial transport in mice.
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
Title: IRBIT governs epithelial secretion in mice by antagonizing the WNK/SPAK kinase pathway.
Results sugest that IRBIT modulates the polyadenylation state of specific mRNAs, both by controlling the cytoplasmic/nuclear partitioning of Fip1 and by inhibiting PAP activity, in response to a stimulus that alters its phosphorylation state.
Title: Inositol 1,4,5-triphosphate receptor-binding protein released with inositol 1,4,5-triphosphate (IRBIT) associates with components of the mRNA 3' processing machinery in a phosphorylation-dependent manner and inhibits polyadenylation.
Data show that pNBC1 activation requires the IRBIT PEST domain, while CFTR activation requires multiple domains, and suggest that IRBIT is a key coordinator of epithelial fluid and HCO3- secretion.
Title: IRBIT coordinates epithelial fluid and HCO3- secretion by stimulating the transporters pNBC1 and CFTR in the murine pancreatic duct.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
