FATP是脂肪酸转运蛋白(fatty acid transport proteins),主要用于运输长链脂肪酸,至少有六种(FATP1-6),各有不同的专一性和组织分布。 脂肪酸与转运蛋白结合后,表观pKa从水溶液中的4.5升高到7.6,结果大约一半的脂肪酸不带电荷,从而能够穿过磷脂双层。 在质膜的内表面,脂肪酸可以与胞质脂肪酸结合蛋白(FABPc)或小窝蛋白1(Caveolin-1)结合。 FABPc使脂肪酸保持可溶性,并可以在细胞内运输到各个细胞区室(细胞器)。 脂肪酸氧化前要先活化,即生成 …
FABP5 controls macrophage alternative activation and ... - Cell Press
2022年11月15日 · In mice with myeloid-specific deletion of fatty acid-binding protein 5 (FABP5), OVA-induced allergic airway inflammation (AAI) is significantly exacerbated by increasing alternatively activated macrophages (M2). Fabp5 deficiency increases IL-4-induced M2 in vitro.
脂肪酸摄取和脂肪酸氧化-脂肪酸(fatty acid)代谢 - 每日生物评论
2023年11月23日 · 脂肪酸氧化(Fatty Acid Oxidation,FAO)是肉碱棕榈酰转移酶 1和2(CPT1和CPT2)将长链脂肪酸转运到线粒体基质后经羟酰基辅酶a氧化为乙酰辅酶a、NADH和FADH2并生成能量的过程,脂肪酸氧化分为四步:
Regulation of macrophage functions by FABP-mediated …
Fatty acid binding proteins (FABPs) represent a family of evolutionarily conserved proteins facilitating lipid transport, metabolism and responses inside cells. More specifically, adipose-FABP (A-FABP) and epidermal-FABP (E-FABP) are highly expressed in macrophages and play a central role in integrating metabolic and inflammatory pathways.

2022年11月16日 · 该研究发现,脂肪酸结合蛋白FABP5主要通过调节长链不饱和脂肪酸 (LCUFAs) -PPARγ-ATP-STAT6通路调节巨噬细胞M2极化,进而调节过敏性哮喘。 该研究为过敏性哮喘的防治提供了新的策略和思路。 过敏性哮喘已经成为一种严重危害公众健康的气道慢性炎症性疾病。 目前,全世界约有一亿哮喘患者。 近年来,研究发现替代激活的巨噬细胞(Alternatively …
A Critical Role of Fatty Acid Binding Protein 4 and 5 (FABP4/5
2013年11月14日 · Cytoplasmic fatty-acid-binding proteins (FABPs) actively facilitate the transport of lipids to specific compartments in cells. FABP4 (also known as aP2/ALBP/A-FABP) and FABP5 (also referred to as mal1/E-FABP) play important roles in the pathogenesis of metabolic diseases.
