Predicted to enable Hsp70 protein binding activity; chaperone binding activity; and misfolded protein binding activity. Predicted to be involved in several processes, including negative regulation of IRE1-mediated unfolded protein response; positive regulation of immunoglobulin production; and ubiquitin-dependent ERAD pathway. Located in cytoplasm and nucleolus. Orthologous to human DNAJB9 (DnaJ heat shock protein family (Hsp40) member B9). [provided by Alliance of Genome Resources, Apr 2022]
