Emerging Roles of Histidine Triad Nucleotide Binding Protein 1 in Neuropsychiatric Diseases

Abstract

The histidine triad nucleotide binding protein1(HINT1),which belongs to the histidine triad(HIT) enzyme superfamily,exerts its enzymic activities as hydrolase or transferase. Its physiological functions are still unclear. HINT1 protein is expressed in various tissues and plays an important role in transcription and signal transduction. Earlier studies have identified HINT1 as a haplo-insufficient tumor suppressor. Other evidences indicate that HINT1 is involved in a wide variety of physiological processes,some of which are irrelevant with its basic enzymic activities. Investigations recently suggest that HINT1 is closely related to many peripheral and central nervous system diseases,and plays a vital role in some of neuropsychiatric diseases such as inherited peripheral neuropathies,schizophrenia,mood disorder,drug addiction,and Down's syndrome. In this review,the role of HINT1 in above-mentioned neuropsychiatric disorders was summarised,and the research findings of HINT1 in each of the above diseases were summarized and analyzed,in order to provide some guidance for further research on this protein.

三联组氨酸核苷结合蛋白1(HINT1)是三联组氨酸(HIT)酶家族成员,作为核苷水解酶或转移酶起作用,其生物学功能尚不清楚。HINT1蛋白可在多种组织中表达,在转录和信号转导中发挥重要作用。早期研究已经明确HINT1是单倍剂量不足的肿瘤抑制因子;也有研究表明HINT1广泛参与一系列生理过程,且部分功能与其基本的酶活性无关;新近研究表明这一蛋白与诸多外周、中枢神经系统疾病存在密切关系,在遗传性周围神经病、精神分裂症、心境障碍、药物成瘾、唐氏综合征等神经精神疾病中起作用。本文针对HINT1蛋白在以上不同神经精神疾病中的作用做了详细综述,分析归纳了HINT1在上述每一种疾病中的研究发现,以期对今后该蛋白的深入研究起到一定的指导作用。.
