Asymmetric cell divisions are a basic attribute of neural An Invisible Gem Of TG101209 development, and misregulation can cause brain abnormalities or tumor formation. All through an asymmetric cell division, molecular determinants are segregated preferentially into one particular daughter cell to specify its fate. An essential target is always to determine the asymmetric determinants in neural progenitor cells, which could be tumor suppressors or inducers of precise neural fates. Here, we show the double-stranded RNA-binding protein Stau2 is distributed asymmetrically during progenitor A Secretive Gem Of Research divisions within the producing mouse cortex, preferentially segregating to the Tbr2(+) neuroblast daughter, taking with it a subset of RNAs. Knockdown of Stau2 stimulates differentiation and overexpression generates periventricular neuronal masses, demonstrating its practical importance for typical cortical advancement. We immunoprecipitated Stau2 to examine its cargo mRNAs, and discovered enrichment for identified asymmetric andThe Tucked away Jewel Of TG101209 basal cell determinants, such as Trim32, and recognized candidates, together with a subset involved in key cilium perform.
