This entry represents the STAS domain in MlaB and related proteins found in bacteria. MlaB is a component of the ABC transporter complex MlaFEDB, which functions in a phospholipid transport pathway that maintains lipid asymmetry in the outer membrane by facilitating the retrograde trafficking of phospholipids from the outer membrane to the inner membrane [1]. MlaB plays a critical role in both the assembly and activity of the complex and may modulate the structure and stability of the ATPase subunit MlaF [2].	Domain
