Protein Family Models

This is a bacterial family of cytoplasmic membrane proteins. It includes two transmembrane regions. The molecular function of FxsA is unknown, but in Escherichia coli its over-expression has been shown to alleviate the exclusion of phage T7 in those cells with an F plasmid. [1]. 10497017. Increased synthesis of an Escherichia coli membrane protein suppresses F exclusion of bacteriophage T7. Wang WF, Margolin W, Molineux IJ;. J Mol Biol 1999;292:501-512. (from Pfam)

Members of this family are predicted membrane proteins homologous to FxsA, named for a phenomenon in Escherichia coli in which overexpression counteracts the ability of F plasmid to cause exclusion of phage T7. The most generally relevant function for members of this family remains unknown.
