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}.
