ELP1 (Elongator Complex Subunit 1), also known as IKBKAP (Inhibitor of Kappa Light Polypeptide Gene Enhancer in B-cells, Kinase Complex-Associated Protein), is a gene located on chromosome 6p21.31 that encodes a subunit of the Elongator complex. The Elongator complex is involved in transcription elongation through histone acetylation and also plays a role in tRNA modification.
ELP1 is a core component of the Elongator complex, which consists of ELP1, ELP2, ELP3, and other subunits:
Hereditary Sensory and Autonomic Neuropathy Type I (HSAN1): ELP1 mutations cause HSAN1, an autosomal dominant disorder characterized by loss of pain and temperature sensation, autonomic dysfunction, and distal muscle weakness. The most common mutation is a T→C transition affecting mRNA splicing.
Amyotrophic Lateral Sclerosis (ALS): ELP1 variants and reduced expression have been associated with ALS risk. The Elongator complex may be particularly important in motor neurons.
Alzheimer's Disease: Elongator deficiency may contribute to synaptic dysfunction in AD through impaired tRNA modification and translation.
The study of Elp1 — Elongator Complex Subunit 1 has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
