Predicted to be involved in several processes, including blood vessel endothelial cell proliferation involved in sprouting angiogenesis; positive regulation of ERK1 and ERK2 cascade; and positive regulation of sprouting angiogenesis. Predicted to act upstream of or within inner ear development; negative regulation of BMP signaling pathway; and ureteric bud development. Predicted to be located in extracellular region. Predicted to be active in extracellular matrix and extracellular space. Orthologous to human BMPER (BMP binding endothelial regulator). [provided by Alliance of Genome Resources, Apr 2022]
