TOR2A (Torsin-2A) is a member of the Torsin family of ATPases, a subgroup of the AAA+ (ATPases Associated with diverse cellular Activities) superfamily. These proteins are characterized by their conserved ATPase domains and involvement in membrane-associated processes. Torsins are predominantly localized in the endoplasmic reticulum (ER) and nuclear envelope, where they contribute to maintaining cellular homeostasis, membrane dynamics, and protein quality control. TOR2A shares structural homology with TOR1A (Torsin-1A), a well-studied family member linked to DYT1 dystonia, a neurological movement disorder caused by a mutation in the TOR1A gene.
While TOR1A has been extensively studied, TOR2A’s biological roles remain less defined. Emerging evidence suggests TOR2A may play a role in cellular stress responses, neurodevelopment, and interactions with other Torsin family members. It is hypothesized to participate in regulating ER-nuclear envelope communication, vesicular trafficking, or modulating the unfolded protein response (UPR). Its expression in various tissues, including the brain, underscores potential relevance to neurological functions and disorders.
Recombinant TOR2A protein, produced via heterologous expression systems (e.g., E. coli, mammalian cells), enables mechanistic studies of its biochemical properties, structure-function relationships, and interactions. Researchers utilize it to investigate ATPase activity, substrate binding, and its interplay with cofactors like LAP1 or LULL1. which regulate Torsin ATPase cycles. Additionally, recombinant TOR2A serves as a tool for exploring its role in disease models, particularly those involving ER stress or nuclear envelope defects.
Despite progress, key questions persist regarding TOR2A’s distinct functions compared to TOR1A and its potential therapeutic implications. Ongoing research aims to clarify its contribution to cellular physiology and pathology, bridging gaps in understanding the Torsin family’s broader impact on human health.
