CC   -!- FUNCTION: ATPase required for the post-translational delivery of tail-
CC       anchored (TA) proteins to the endoplasmic reticulum. Recognizes and
CC       selectively binds the transmembrane domain of TA proteins in the
CC       cytosol. This complex then targets to the endoplasmic reticulum by
CC       membrane-bound receptors, where the tail-anchored protein is released
CC       for insertion. This process is regulated by ATP binding and hydrolysis.
CC       ATP binding drives the homodimer towards the closed dimer state,
CC       facilitating recognition of newly synthesized TA membrane proteins. ATP
CC       hydrolysis is required for insertion. Subsequently, the homodimer
CC       reverts towards the open dimer state, lowering its affinity for the
CC       membrane-bound receptor, and returning it to the cytosol to initiate a
CC       new round of targeting. {ECO:0000255|HAMAP-Rule:MF_03112}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_03112}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_03112}.
CC       Endoplasmic reticulum {ECO:0000255|HAMAP-Rule:MF_03112}.
CC   -!- SIMILARITY: Belongs to the arsA ATPase family. {ECO:0000255|HAMAP-
CC       Rule:MF_03112}.
