BioVector® YB332研究蛋白质修饰和脂肪酸代谢的模式酵母单倍体菌株
基因型:
MATa ura3 leu2-3 his3 ade2 lys2交配型:
MATa营养缺陷型: 具有尿嘧啶(ura3)、亮氨酸(leu2)、组氨酸(his3)、腺嘌呤(ade2)和赖氨酸(lys2)的合成缺陷。这意味着它必须在添加了这些营养物质的完全培养基(如 YPD)或相应的合成缺失培养基(SC 缺失培养基)中生长。

2. 核心研究应用
蛋白质 N-肉豆蔻酰化(N-myristoylation): 它是研究 N-肉豆蔻酰转移酶(Nmt1p)功能的关键菌株。科研人员利用 YB332 及其衍生突变株来探索蛋白质如何通过脂质修饰定位到细胞膜上。
脂肪酸代谢: YB332 常用于研究脂肪酸的转运和激活过程(如 Faa1p 和 Faa4p 蛋白)。它是研究细胞如何吸收和利用外源脂肪酸的重要工具。
钙信号传导: 该菌株也被用于研究钙调神经磷酸酶(Calcineurin)的激活及其对环境压力的响应。
推荐培养基:
YPD 培养基: 1% 酵母提取物,2% 蛋白胨,2% 葡萄糖。
SC 缺失培养基: 用于筛选转化质粒或进行遗传选育。
生长温度: 最适生长温度为 24°C 至 30°C。在某些涉及温度敏感型(ts)突变的研究中,可能会在 37°C 下观察其表型变化。
保存方式: 长期保存建议使用 15%-25% 的甘油溶液,置于 -80°C 超低温冰箱中。
MATa ura3 leu2-3 his3 ade2 lys2. It is often used as the "wild-type" (control) strain in research studies that involve genetic modifications to explore specific gene functions.Model Organism: As a Saccharis cerevisiae strain, it serves as a nonpathogenic model organism for studying fundamental eukaryotic cellular processes, including cell division, gene expression, and protein interactions.
Fatty Acid Metabolism Studies: It is widely used in studies concerning fatty acid transport and activation proteins (Faa1p, Faa4p, etc.). Researchers use it to understand how cells uptake and metabolize exogenous fatty acids.
N-myristoylation Research: The strain has been instrumental in studying protein N-myristoylation, a critical process for protein function and localization. It helps investigate how N-myristoyltransferase (Nmt1p) activity regulates cellular processes, such as the calcium sensitivity of calcineurin activation.
Genetic Manipulation: YB332 is amenable to standard genetic manipulation techniques, including transformation with plasmids and gene deletions, which makes it a versatile tool for laboratory experiments.
Growth Conditions: In lab settings, it is typically grown in YPD (yeast extract/peptone/dextrose) or synthetic complete media (SC) at temperatures around 24°C to 30°C.
