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 GET1 and GET2, where the tail-anchored protein
CC is released for insertion. This process is regulated by ATP binding and
CC hydrolysis. ATP binding drives the homodimer towards the closed dimer
CC state, facilitating recognition of newly synthesized TA membrane
CC proteins. ATP hydrolysis is required for insertion. Subsequently, the
CC homodimer reverts towards the open dimer state, lowering its affinity
CC for the GET1-GET2 receptor, and returning it to the cytosol to initiate
CC a new round of targeting. Cooperates with the HDEL receptor ERD2 to
CC mediate the ATP-dependent retrieval of resident ER proteins that
CC contain a C-terminal H-D-E-L retention signal from the Golgi to the ER.
CC Involved in low-level resistance to the oxyanions arsenite and
CC arsenate, and in heat tolerance. {ECO:0000255|HAMAP-Rule:MF_03112}.
CC -!- SUBUNIT: Homodimer. Component of the Golgi to ER traffic (GET) complex,
CC which is composed of GET1, GET2 and GET3. Within the complex, GET1 and
CC GET2 form a heterotetramer which is stabilized by phosphatidylinositol
CC binding and which binds to the GET3 homodimer. Interacts with the
CC chloride channel protein GEF1. {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}. Golgi
CC apparatus {ECO:0000255|HAMAP-Rule:MF_03112}. Note=GET1 and GET2 are
CC required for targeting GET3 to the endoplasmic reticulum.
CC {ECO:0000255|HAMAP-Rule:MF_03112}.
CC -!- SIMILARITY: Belongs to the arsA ATPase family. {ECO:0000255|HAMAP-
CC Rule:MF_03112}.
