Ifrd1 Protein Interferon Related Developmental Regulator 1 is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
IFRD1 Protein (Interferon-Related Developmental Regulator 1) is a 415-amino acid protein involved in transcriptional regulation, cellular differentiation, and neuroprotection [1]. The protein is expressed in various tissues, with highest levels in the brain and spinal cord, particularly in neurons and motor neurons [2].
¶ Domain Organization
- N-terminal Domain: Involved in protein-protein interactions
- Central Region: Regulatory domain
