Evolutionary conservation of Notch signaling inhibition by TMEM131L overexpression
چکیده انگلیسی
Human KIAA0922/TMEM131L encodes a transmembrane protein, TMEM131L, that regulates the canonical Wnt/β-catenin signaling pathway by eliciting the lysosome-dependent degradation of phosphorylated LRP6 co-receptor. Here, we use a heterospecific Drosophila transgenic model to examine the potential evolutionary conservation of TMEM131L function. Analysis of TMEM131L transgenic flies shows that TMEM131L interference with the Wnt pathway results primarily from a Notch-dependent decrease in Wingless production. Consistently, lentivirus-mediated overexpression of TMEM131L in human CD34+ hematopoietic progenitor cells leads to decreased susceptibility to Notch1 ligation and defective commitment toward the T lineage. These results show that TMEM131L corresponds to an evolutionary conserved regulator of the Notch signaling pathway.
