Adenosylhomocysteinase-like 1

IRBIT, S-adenosyl homocysteine hydrolase, DCAL
The protein encoded by this gene interacts with inositol 1,4,5-trisphosphate receptor, type 1 and may be involved in the conversion of S-adenosyl-L-homocysteine to L-homocysteine and adenosine. Several transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Jun 2011] (from NCBI)

UNASSIGNED: Besides its capacity to inhibit the 1,4,5-trisphosphate (IP3 ) receptor, the regulatory protein IRBIT (IP3 receptor-binding protein released with IP3 ) is also able to control the activity of numerous ion channels and electrolyte transporters and thereby creates an optimal electrolyte composition of various biological fluids.

Adenosine reagent-free detection by co-immobilization of adenosine deaminase and phenol red on an optical biostrip.
Clonis et al., Athens, Greece. In Biotechnol J, 2015
Adenosine can be determined enzymatically using either S-adenosyl-homocysteine hydrolase and (3) [H]-adenosine, or adenosine kinase combined with GTP and luciferase, or an amperometric biosensor carrying adenosine deaminase (ADA), purine nucleoside phosphorylase, and xanthine oxidase.
Role of IP3 receptor signaling in cell functions and diseases.
Mikoshiba, Wako, Japan. In Adv Biol Regul, 2015
Moreover, IP3 was found not only to release Ca(2+), but also to release IRBIT (IP3receptor binding protein released with inositol trisphosphate) essential for the regulation of acid-base balance, RNA synthesis and ribonucleotide reductase.

IRBIT inhibits ribonucleotide reductase (RNR) by stabilizing dATP binding to the RNR activity site.
IRBIT: a regulator of ion channels and ion transporters.
Mikoshiba et al., Wako, Japan. In Biochim Biophys Acta, 2014
IRBIT (also called AHCYL1) was originally identified as a binding protein of the intracellular Ca(2+) channel inositol 1,4,5-trisphosphate (IP3) receptor and functions as an inhibitory regulator of this receptor.
Enzyme regulation. IRBIT is a novel regulator of ribonucleotide reductase in higher eukaryotes.
Dasso et al., Bethesda, United States. In Science, 2014
Here, we show that the metazoan protein IRBIT forms a deoxyadenosine triphosphate (dATP)-dependent complex with RNR, which stabilizes dATP in the activity site of RNR and thus inhibits the enzyme.

Mechanism and synergism in epithelial fluid and electrolyte secretion.
Muallem et al., Bethesda, United States. In Pflugers Arch, 2014
The function of the transporters is regulated by multiple inputs, which in the duct include major regulation by the WNK/SPAK pathway that inhibit secretion and the IRBIT/PP1 pathway that antagonize the effects of the WNK/SPAK pathway to both stimulate and coordinate the secretion.
