2024年12月25日 · OAS1 (2'-5'-Oligoadenylate Synthetase 1) is a Protein Coding gene. Diseases associated with OAS1 include Immunodeficiency 100 With Pulmonary Alveolar Proteinosis And Hypogammaglobulinemia and Infantile-Onset Pulmonary Alveolar Proteinosis-Hypogammaglobulinemia.
OAS1 - Wikipedia
2'-5'-oligoadenylate synthetase 1 is an enzyme that in humans is encoded by the OAS1 gene. [5][6] This gene encodes a member of the 2-5A synthetase family, which include essential proteins involved in the innate immune response to viral infection.
Activation of Oas1a gene expression by type I IFN requires both …
2012年4月10日 · Oas1a is an active synthetase with broad antiviral activity mediated through RNase L. Oas1b is inactive but can inhibit Oas1a synthetase activity and mediate a flavivirus-specific antiviral activity through an unknown RNase L-independent mechanism.
2'-5'-寡聚腺苷酸合成酶 1(OAS1)基因 - MCE-生物活性 ...
这种干扰素诱导的基因编码一种合成 2',5'-寡聚腺苷酸 (2-5As) 的蛋白质。 这种蛋白质在先天细胞抗病毒反应中起着关键作用,并与其他细胞过程如细胞生长和细胞凋亡有关。 可变剪接导致具有不同酶活性的多个转录变体。 该基因的多态性与病毒感染的易感性有关,包括 SARS-CoV-2 和 1 型糖尿病。 该基因位于 12 号染色体上的一组相关基因中。 [RefSeq 提供,2022 年 5 月] This interferon-induced gene encodes a protein that synthesizes 2',5'-oligoadenylates (2-5As).
Type I interferon sensing unlocks dormant adipocyte ... - Nature
2020年6月2日 · We show that activation of the type I interferon (IFN)/IFNα receptor (IFNAR) axis amplifies adipocyte inflammatory vigor and uncovers dormant gene expression patterns resembling inflammatory...
OAS cross-activates RNase L intercellularly through cell-to-cell ...
2025年2月25日 · OAS high tumors naturally produce 2-5A that induces antitumor immunity. The 2′,5′-oligoadenylate synthetase (OAS)-RNase L pathway is a classical antiviral innate immune pathway. Upon sensing dsRNA, OAS produces 2′,5′-oligoadenylate (2-5A) as a second messenger to activate RNase L.
Activation of Oas1a gene expression by type I IFN requires ... - PubMed
2012年4月10日 · The murine 2'-5' oligoadenylate synthetase 1a (Oas1a) and Oas1b genes are type 1 IFN responsive genes. Oas1a is an active synthetase with broad antiviral activity mediated through RNase L. Oas1b is inactive but can inhibit Oas1a synthetase activity and mediate a flavivirus-specific antiviral activit …
多组学分析揭示干扰素刺激基因 OAS1 作为泛癌的预后和免疫生物 …
简介OAS1(2'-5'-寡腺苷酸合成酶1)是干扰素刺激基因的成员,在抗病毒过程中发挥着重要作用。 近年来,OAS1在肿瘤中的作用引起人们的关注,并发现它与多种肿瘤的预后相关。 然而,OAS1影响肿瘤的机制尚不清楚,有必要对OAS1进行泛癌研究,以更好地了解其在癌症中的意义。 方法采用TCGA分析OAS1在泛癌中的表达、预后价值、遗传改变、选择性剪接事件、GTEx、HPA、GEPIA 和 OncoSplicing 数据库。 使用 ESTIMATE、xCell、CIBERSORT 和 …
