Product Description

Recombinant human ADARB1 (ADAR2L) (2-741) was expressed by baculovirus in Sf9 insect cells using an N-terminal Flag tag. The gene accession number is NM_015833.4 (transcript variant 2, canonical sequence).

 

Scientific Background

Adenosine deaminases acting on RNA (ADARs) are enzymes that catalyze the chemical conversion of denosines to inosines in double-stranded RNA (dsRNA) substrates. ADARB1 (ADAR2L – Adenosine Deaminase Acting on RNA 2 Long Isoform) is an RNAediting enzyme that modifies adenosine to inosine in doublestranded RNA, impacting RNA splicing, stability, and translation. It contains double-stranded RNA-binding domains and a catalytic deaminase domain, enabling precise substrate recognition and editing. ADAR2L plays a critical role in the nervous system, with its editing of the GRIA2 mRNA Q/R site being essential for proper AMPA receptor function and neuronal calcium regulation (1). This editing safeguards neurons against excitotoxicity, supporting neural plasticity and development. Dysregulation of ADAR2L activity has been associated with neurological diseases and phsycatric disorders (2). Additionally, altered ADAR2L expression may contribute to cancer progression by disrupting RNA processing (3). Its specificity and critical biological roles make it a potential therapeutic target in neurological and oncological disorders.
