Cytoskeleton bacteria
WebHotspot mutations in the NRAS gene are causative genetic events associated with the development of melanoma. Currently, there are no FDA-approved drugs directly targeting NRAS mutations. Previously, we showed that p38 acts as a tumor suppressor in vitro and in vivo with respect to NRAS-mutant melanoma. We observed that because of p38 … WebMreB is a bacterial cytoskeleton protein that has been widely studied and is associated with the determination of rod shape as well as important subcellular processes including …

Bacteria also have multiple homologues of actin that are involved in everything from cell division (FtsA), plasmid partitioning (ParM and AlfA), organelle organization (MamK), and regulation of cell growth and chromosome segregation (MreB). Not surprisingly, these proteins all have distinct localization patterns.
