  • Interestingly, numerous IS elements (for example, IS1341 , IS809 and IS1136 ) encode TnpB as the only protein (putative transposase), but the supporting evidence for TnpB-mediated transposition is still missing. (biomedcentral.com)
  • Hence, although rare, IAP-induced local heterochromatin spreading into nearby genes may influence expression and, in turn, host fitness. (prolekarniky.cz)
  • The data generated from spatial transcriptomics experiments typically consists of gene expression levels associated with specific spatial coordinates. (gatech.edu)
