Predicted to enable WW domain binding activity. Predicted to be involved in several processes, including negative regulation of transport; positive regulation of protein ubiquitination; and ubiquitin-dependent protein catabolic process. Predicted to be located in mitochondrion. Predicted to be integral component of membrane. Predicted to be active in Golgi apparatus; endoplasmic reticulum; and perinuclear region of cytoplasm. Is expressed in several structures, including alimentary system; central nervous system; lower urinary tract; sensory organ; and trigeminal nerve. Orthologous to human NDFIP2 (Nedd4 family interacting protein 2). [provided by Alliance of Genome Resources, Apr 2022]
