NEDD4 Binding Protein 2 Like 1, commonly abbreviated as NEDD4L or NEDD4-2, is a significant member of the HECT (homologous to the E6-AP carboxyl terminus) family of E3 ubiquitin ligases. The corresponding gene for NEDD4L is referred to as "NEDD4L."NEDD4L is a cytoplasmic enzyme that plays an essential role in post-translational modification of proteins through ubiquitination, a process that typically targets proteins for degradation by the proteasome, alters their cellular location, affects their activity, or facilitates or prevents protein interactions. Ubiquitination by NEDD4L involves the attachment of ubiquitin, a small regulatory protein, to specific lysine residues on substrate proteins, which can lead to various outcomes depending on the number of ubiquitin molecules added and the ubiquitination pattern.

One of the well-characterized functions of NEDD4L is the regulation of ion transport across cellular membranes. NEDD4L is known to ubiquitinate and thus regulate the stability and function of various ion channels and transporters, including the epithelial sodium channel (ENaC). Through its impact on ENaC, NEDD4L indirectly influences blood pressure and volume homeostasis, making it a protein of interest in the study of hypertension and fluid balance disorders.Additionally, NEDD4L has been implicated in signaling pathways related to cell growth and proliferation, as well as in the regulation of other cellular processes due to its ability to ubiquitinate a wide range of substrates. Aberrations in the function of NEDD4L have been associated with various pathologies, including cancer, where altered ubiquitination patterns may contribute to tumorigenesis by affecting the degradation of proteins that regulate cell cycle and apoptosis.
