摘要
s -酰化(或棕榈酰化)是一种可逆的翻译后修饰(PTM)，可调节蛋白质活性、信号转导和运输。棕榈酰化被发现显著影响各种参与病原体进入的膜受体的活性，如CCR5 (HIV)和炭疽毒素受体、细胞增殖(表皮生长因子受体)、心脏功能(β-肾上腺素能受体)或突触功能(AMPA受体)。这些膜受体的棕榈酰化不仅影响它们的内化、定位和激活，还影响其他PTMs，如磷酸化。在这篇综述中，我们讨论了最近的研究结果显示棕榈酰化如何不同地影响这些膜受体的生物学。
How palmitoylation affects trafficking and signaling of membrane receptors
S-acylation (or palmitoylation) is a reversible post-translational modification (PTM) that modulates protein activity, signalization and trafficking. Palmitoylation was found to significantly impact the activity of various membrane receptors involved in either pathogen entry, such as CCR5 (for HIV) and anthrax toxin receptors, cell proliferation (epidermal growth factor receptor), cardiac function (β-Adrenergic receptor), or synaptic function (AMPA receptor). Palmitoylation of these membrane receptors indeed affects not only their internalization, localization, and activation, but also other PTMs such as phosphorylation. In this review, we discuss recent results showing how palmitoylation differently affects the biology of these membrane receptors.
期刊介绍：
The journal publishes original research articles and reviews on all aspects of cellular, molecular and structural biology, developmental biology, cell physiology and evolution. It will publish articles or reviews contributing to the understanding of the elementary biochemical and biophysical principles of live matter organization from the molecular, cellular and tissues scales and organisms.
This includes contributions directed towards understanding biochemical and biophysical mechanisms, structure-function relationships with respect to basic cell and tissue functions, development, development/evolution relationship, morphogenesis, stem cell biology, cell biology of disease, plant cell biology, as well as contributions directed toward understanding integrated processes at the organelles, cell and tissue levels. Contributions using approaches such as high resolution imaging, live imaging, quantitative cell biology and integrated biology; as well as those using innovative genetic and epigenetic technologies, ex-vivo tissue engineering, cellular, tissue and integrated functional analysis, and quantitative biology and modeling to demonstrate original biological principles are encouraged.
