NDFIP1 (Nedd4 family interacting protein 1) is an adaptor protein belonging to the Nedd4 (neural precursor cell expressed developmentally down-regulated protein 4) protein family. It was originally identified in a Nedd4-binding protein screen. It resides in the Golgi and post-Golgi vesicles, and is composed of three transmembrane domains.

Storage: -20C
Application: All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry. The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

Biochem Physiol Actions: NDFIP1 (Nedd4 family interacting protein 1) binds with membrane proteins and controls their interaction with cytoplasmic protein Nedd4 (neural precursor cell expressed developmentally down-regulated protein 4). In brain, it is co-expressed with Nedd4 in neurons, and during neuronal injury, their interaction is critical for promoting the survival of cortical neurons. It is neuroprotective, and in collaboration with Nedd4, ubiquitinates and removes harmful proteins, post brain-injury. It maintains iron homeostasis in cells by interacting with divalent metal transporter 1 (DMT1) and promoting its degradation. In brains of Parkinson's disease (PD) patients, this protein is found to be expressed in astrocytes, where it is normally absent. Elevation in Parkinsonian brain iron levels leads to the up-regulation of NDFIP1 protein for the control of DMT1.
