Introduction

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.

Overview

NHLRC2 (NHL Repeat Containing 2) is a protein encoded by the NHLRC2 gene located on chromosome 10p13[@sarda2019]. 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[@wickramasinghe2020].

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.
