產(chǎn)品介紹 |
background: Musashi1 (Msi1) is an RNA-binding protein expressed in neural progenitor cells and neural stem cells. Msi1 is the mammalian homolog of Drosophila Musashi. The gene encoding human Msi1 encodes a 362 amino acid protein. In murine embryonic neural progenitor cells, Msi1 localizes to the cytoplasm and is downregulated during differentiation. Msi1 binds to NUMB, which encodes a membrane-associated antagonist of Notch signaling. Msi1 appears to function in the proliferation and maintenance of stem cell populations of the central nervous system. In addition to its usefulness as a marker for neural progenitor cells in normal human brains, Msi1 is also a marker for human gliomas. In rats, Msi1 is expressed in Sertoli cells of the testis and granulosa cells of the ovary. Function: RNA binding protein that regulates the expression of target mRNAs at the translation level. Regulates expression of the NOTCH1 antagonist NUMB. Binds RNA containing the sequence 5'-GUUAGUUAGUUAGUU-3' and other sequences containing the pattern 5'-[GA]U(1-3)AGU-3'. May play a role in the proliferation and maintenance of stem cells in the central nervous system. Subcellular Location: Cytoplasm. Nucleus. Tissue Specificity: Detected in fetal kidney, brain, liver and lung, and in adult brain and pancreas. Detected in hepatoma cell lines. Similarity: Belongs to the Musashi family. Contains 2 RRM (RNA recognition motif) domains.

Musashi1是一種進(jìn)化保守的RNA結(jié)合蛋白,在維持干細(xì)胞狀態(tài)、分化和腫瘤發(fā)生方面起著重要作用。Musashi1 選擇性地表達(dá)在神經(jīng)前體細(xì)胞上,包括神經(jīng)干細(xì)胞上。在神經(jīng)系統(tǒng)外,Musashi1還是腸干細(xì)胞的選擇性標(biāo)記。這些組織干細(xì)胞或未成熟細(xì)胞Musashi1的表達(dá),表明Musashi1在轉(zhuǎn)錄后基因調(diào)節(jié)階段維持這些細(xì)胞未分化狀態(tài)起重要作用。Musashi1過度表達(dá)通過依賴RBP2Jk的旁路激活Notch1,而Notch信號(hào)途徑功能為誘導(dǎo)哺乳動(dòng)物神經(jīng)干細(xì)胞自我更新。通過musashi1-P-小鼠培養(yǎng)腦細(xì)胞的Musashi蛋白產(chǎn)物反義去除研究,發(fā)現(xiàn)這些基因在維持神經(jīng)干細(xì)胞未分化狀態(tài)起著重要的作用。 Musashi抑制m-Numb轉(zhuǎn)錄的分子機(jī)制尚待進(jìn)一步研究。Musashi1有可能除轉(zhuǎn)錄調(diào)控外還參與其他調(diào)控途徑。另外,Musashi1還表達(dá)在一些腦腫瘤的特殊類型(這些腫瘤可能起源自非成熟腦細(xì)胞),并且表達(dá)水平和腫瘤的惡性程度及增殖能力相關(guān)。 |
