Predicted to enable several functions, including adenyl-nucleotide exchange factor activity; chaperone binding activity; and tau protein binding activity. Predicted to be involved in negative regulation of protein binding activity; protein stabilization; and regulation of cellular protein metabolic process. Predicted to act upstream of or within protein metabolic process. Predicted to be located in axon and dendrite. Predicted to be part of chaperone complex. Predicted to colocalize with dendritic microtubule. Orthologous to human BAG2 (BAG cochaperone 2). [provided by Alliance of Genome Resources, Apr 2022]
