Study shows that, when uropathogenic E. coli infect bladder epithelial cells, they are targeted by autophagy but avoid degradation because of their capacity to neutralize lysosomal pH. This change is detected by TRPML3, TRPML3 activation then spontaneously initiates lysosome exocytosis, resulting in expulsion of exosome-encased bacteria.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
