Predicted to enable chaperone binding activity; protein homodimerization activity; and unfolded protein binding activity. Predicted to be involved in chaperone-mediated protein folding; negative regulation of cardiac muscle cell apoptotic process; and positive regulation of angiogenesis. Predicted to be located in several cellular components, including Golgi apparatus; cytosol; and nucleolus. Is expressed in brain subventricular zone; lung; retina inner nuclear layer; retina outer nuclear layer; and smooth muscle tissue. Orthologous to human HSPB6 (heat shock protein family B (small) member 6). [provided by Alliance of Genome Resources, Apr 2022]
