Nhlrc2 Protein — Nhl Repeat Containing 2 is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
NHLRC2 (NHL Repeat Containing 2) is a protein encoded by the NHLRC2 gene located on chromosome 10p13. The protein contains multiple NHL (NCL-1, HT2A, LIN-41) repeats, which are known to mediate protein-protein interactions and are often found in proteins involved in RNA processing and post-translational modification.
While initially characterized in the context of cancer and developmental disorders, emerging research suggests NHLRC2 may play important roles in cellular stress responses and protein homeostasis relevant to neurodegenerative diseases.
