TAC1(Tachykinin precursor 1,速激肽前体1)基因编码速激肽家族(Tachykinin family)的神经肽前体蛋白,该家族成员均含有共同的C端序列“Phe-X-Gly-Leu-Met”(X为可变氨基酸),通过G蛋白偶联受体(一种跨膜蛋白,负责传递细胞外信号)发挥作用。TAC1经剪切可产生多种活性肽,包括P物质(Substance P)、神经激肽A(Neurokinin A)等,主要分布于中枢神经系统和周围神经,参与痛觉传递、炎症反应、平滑肌收缩及情绪调节。其作用位点包括神经元突触(神经细胞间的连接结构)、免疫细胞和血管内皮细胞。TAC1突变可能导致神经肽分泌异常,与慢性疼痛、哮喘、炎症性肠病和抑郁症相关。过表达TAC1会增强痛觉敏感性和炎症反应,例如在关节炎患者中观察到P物质水平升高;而降低表达(如通过基因敲除)可减轻疼痛和炎症,但可能影响情绪调节功能。该基因与TAC3(编码神经激肽B)等同属速激肽家族,家族共性为通过NK1R、NK2R等受体(NK即Neurokinin,神经激肽受体)调控神经与免疫系统交叉反应。在癌症中,TAC1过表达可能促进肿瘤血管生成(通过P物质刺激血管生长),而某些神经系统疾病如纤维肌痛与其功能紊乱有关。

This gene encodes four products of the tachykinin peptide hormone family, substance P and neurokinin A, as well as the related peptides, neuropeptide K and neuropeptide gamma. These hormones are thought to function as neurotransmitters which interact with nerve receptors and smooth muscle cells. They are known to induce behavioral responses and function as vasodilators and secretagogues. Substance P is an antimicrobial peptide with antibacterial and antifungal properties. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2014]

该基??因编码四种产品的速激肽激素家族,P物质和神经激肽A的,以及相关的肽,神经肽K和神经肽伽马。这些激素被认为充当其与神经受体和平滑肌细胞相互作用的神经递质。它们被称为诱导行为反应并用作血管扩张剂和分泌。 P物质是具有抗菌和抗真菌特性的抗微生物肽。已发现该基因编码不同亚型的多个抄本变形。 [由RefSeq的,2014年11月提供]
