NEDD4 family-interacting protein 2

Gene

NDFIP2

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Activates HECT domain-containing E3 ubiquitin-protein ligases, including ITCH, NEDD4, NEDD4L, SMURF2, WWP1 and WWP2, and consequently modulates the stability of their targets. As a result, may control many cellular processes. Recruits ITCH, NEDD4 and SMURF2 to endosomal membranes. May modulate EGFR signaling.3 Publications

Undergoes transient tyrosine-phosphorylation following EGF stimulation, most probably catalyzed by SRC. Also phosphorylated by LYN and FYN.1 Publication

Interactioni

Subunit structurei

Forms heterodimers with NDFIP1. Interacts with HECT domain-containing E3 ubiquitin-protein ligases, including NEDD4. Interacts with NEDD4L (By similarity). Interacts with PTEN. When phosphorylated at Tyr-167, interacts with SRC and LYN SH2 domain. May thus act as a scaffold that recruits SRC to NDFIP1, enhancing NDFIP1 phosphorylation. Interacts with SLC11A2/DMT1. May interact with phosphorylated EGFR.By similarity3 Publications
