General annotation (Comments)

Function	ATPase required for the post-translational delivery of tail-anchored (TA) proteins to the endoplasmic reticulum. Recognizes and selectively binds the transmembrane domain of TA proteins in the cytosol. This complex then targets to the endoplasmic reticulum by membrane-bound receptors, where the tail-anchored protein is released for insertion. This process is regulated by ATP binding and hydrolysis. ATP binding drives the homodimer towards the closed dimer state, facilitating recognition of newly synthesized TA membrane proteins. ATP hydrolysis is required for insertion. Subsequently, the homodimer reverts towards the open dimer state, lowering its affinity for the membrane-bound receptor, and returning it to the cytosol to initiate a new round of targeting By similarity. May be involved in insulin signaling. Ref.12 Ref.13
Subunit structure	Homodimer By similarity. Component of a transmembrane domain recognition complex (TRC) By similarity. Interacts with SERP1 and SEC61B By similarity. Interacts with WRB. Ref.12 Ref.13 Ref.15
Subcellular location	Cytoplasm. Endoplasmic reticulum. Nucleus › nucleolus Ref.10 Ref.12 Ref.15.
Tissue specificity	Expressed in the epithelial cells of the liver, kidney, and stomach wall, in the adrenal medulla, in the islet cells of the pancreas, in the red pulp of the spleen, and in cardiac and skeletal muscle. Ref.11
Sequence similarities	Belongs to the arsA ATPase family.
Biophysicochemical properties	Kinetic parameters: KM=0.22 mM for ATP Ref.9 Vmax=16.6 nmol/min/mg enzyme for ATP
Sequence caution	The sequence AAC50731.1 differs from that shown. Reason: Frameshift at position 19.
