PDZRN4 (PDZ Domain-Containing RING Finger Protein 4), also known as LHFP or HH18. is a member of the PDZRN protein family characterized by the presence of a PDZ (Postsynaptic Density-95/Discs Large/Zonula Occludens-1) domain and a RING (Really Interesting New Gene) finger domain. The PDZ domain facilitates protein-protein interactions, often mediating the assembly of signaling complexes, while the RING finger domain confers E3 ubiquitin ligase activity, suggesting a role in ubiquitination-dependent protein degradation or regulation.
PDZRN4 is implicated in diverse cellular processes, including neuronal development, muscle differentiation, and tissue homeostasis. Studies highlight its involvement in regulating Wnt/β-catenin and Notch signaling pathways, which are critical for cell proliferation, differentiation, and apoptosis. In the nervous system, PDZRN4 influences synaptic organization and axon guidance by interacting with postsynaptic scaffolding proteins. Additionally, it has been linked to myogenesis, where it modulates myoblast fusion and muscle fiber formation.
Aberrant PDZRN4 expression is associated with pathological conditions. For instance, it is downregulated in certain cancers (e.g., osteosarcoma, breast cancer) and may act as a tumor suppressor by promoting ubiquitination and degradation of oncogenic proteins. Conversely, its overexpression has been noted in neurodegenerative disorders, though the mechanisms remain unclear.
Despite progress, PDZRN4's precise molecular functions and regulatory networks are not fully elucidated. Its dual-domain structure suggests a bridging role between signaling pathways and proteasomal degradation, positioning it as a potential therapeutic target or biomarker. Further research is needed to unravel its context-dependent roles in health and disease.
