Zika virions likely bind phosphatidylserine receptors to enter fetal neural progenitor cells and impede normal brain growth.

During tissue patterning, the transcriptional response of cells to inductive signals relies on tissue‐intrinsic competence to induce specific target genes and the ability of cells to interpret dynamics in morphogen exposure and signaling through transcriptional networks.

Proximity labeling for proteomic profiling To achieve regional protein labeling, the enzymes are usually fused with a targeting signal peptide or a spatially‐restricted protein (SP). The enzymes can also be fused with any protein of interest for protein interactome studies. After performing proximity labeling in living cells, the cells are lysed and the biotinylated endogenous proteins are isolated using steptavidin beads. Small peptides of enriched proteins are generated by trypsin digestion and subsequently ionized for MS analysis. The mass‐to‐charge (m/z) ratio of each peptide is then used to identify peptide sequence usually through computational comparison against established databases.
