TDP-43 Protein Pathology and RNA Splicing in ALS

Overview of TDP-43 Function

Normal Role: TDP-43 (TAR DNA-binding protein 43) is primarily a nuclear protein involved in regulating RNA metabolism, including transcription, transport, stability, and particularly RNA splicing.
Pathological Shift: In Amyotrophic Lateral Sclerosis (ALS), TDP-43 mislocalizes from the nucleus, forming abnormal cytoplasmic inclusions, and is depleted from its normal nuclear site of action.

Connection to RNA Splicing Errors

Loss of Nuclear Function: The depletion of functional TDP-43 from the nucleus leads to a direct loss of normal RNA regulation.
Cryptic Exons: Without sufficient nuclear TDP-43, the cellular machinery fails to properly suppress cryptic exons (non-coding sequences normally excluded from mature messenger RNA), resulting in aberrant splicing events.
Downstream Toxicity: These widespread splicing errors produce truncated or dysfunctional proteins, ultimately contributing to neurodegeneration and the death of motor neurons characteristic of ALS.
