Predicted to enable chaperone binding activity. Predicted to be involved in cytoplasmic sequestering of protein; maintenance of unfolded protein involved in ERAD pathway; and tail-anchored membrane protein insertion into ER membrane. Predicted to be located in chromosome; cytoplasm; and nuclear lumen. Predicted to be part of BAT3 complex. Predicted to be active in cytosol. Is expressed in neural retinal epithelium; retina inner nuclear layer; retina nuclear layer; and retina outer nuclear layer. Orthologous to human GET4 (guided entry of tail-anchored proteins factor 4). [provided by Alliance of Genome Resources, Apr 2022]
