关于 IMPA1

Cytogenetic location: 8q21.13 Genomic coordinates (GRCh38): 8:81,656,914-81,686,325 (from NCBI)

This gene has 13 transcripts (splice variants), 232 orthologues, 4 paralogues and is associated with 1 phenotype. Ubiquitous expression in testis (RPKM 15.5), thyroid (RPKM 10.4) and 24 other tissues.

功能概要

该基因编码一种酶，该酶可使肌醇单磷酸去磷酸化以产生游离肌醇 (磷脂酰肌醇的前体) ，因此是通过产生第二信使肌醇 1,4,5-三磷酸和甘油二酯进行细胞内信号转导的重要调节剂.该酶还可以使用肌醇 1,3-二磷酸、肌醇 1,4-二磷酸、鲨肌醇-磷酸、葡萄糖-1-磷酸、葡萄糖-6-磷酸、果糖-1-磷酸、β -甘油磷酸盐和 2'-AMP 作为底物。这种酶表现出镁依赖性磷酸酶活性，并被治疗浓度的锂抑制。抑制肌醇单磷酸水解和随后用于磷脂酰肌醇合成的肌醇耗尽可以解释锂治疗双相情感障碍的抗躁狂和抗抑郁作用。可变剪接导致编码不同异构体的多个转录变体。该基因的假基因也存在于染色体 8q21.13 上。[RefSeq 提供，2014 年 12 月]

This gene encodes an Enzyme that dephosphorylates myo-inositol monophosphate to generate free myo-inositol, a precursor of phosphatidylinositol, and is therefore an important modulator of intracellular signal transduction via the production of the second messengers myoinositol 1,4,5-trisphosphate and diacylglycerol. This Enzyme can also use myo-inositol-1,3-diphosphate, myo-inositol-1,4-diphosphate, scyllo-inositol-phosphate, glucose-1-phosphate, glucose-6-phosphate, fructose-1-phosphate, beta-glycerophosphate, and 2'-AMP as substrates. This Enzyme shows magnesium-dependent Phosphatase activity and is inhibited by therapeutic concentrations of lithium. Inhibition of inositol monophosphate hydroylosis and subsequent depletion of inositol for phosphatidylinositol synthesis may explain the anti-manic and anti-depressive effects of lithium administered to treat bipolar disorder. Alternative splicing results in multiple transcript variants encoding distinct isoforms. A pseudogene of this gene is also present on chromosome 8q21.13. [provided by RefSeq, Dec 2014]
