Background InformationNebulin (UniProt: P20929; also known as NEB, NEM2) is encoded by the NEB gene (Gene ID: 4703) in human. Nebulin is a highly conserved, muscle-specific protein that is located in the thin filament of striated muscle. It is involved in maintaining the structural integrity of sarcomeres and the membrane system associated with the myofibrils. It is shown to bind and stabilize F-actin. Nebulin has a highly repetitive protein structure with about 97% of the protein consisting of modules of 30 to 35 amino-acids arranged into simple repeats or super repeats. Each repeat binds to actin along the length of the thin filament. The repeat modules contain conserved SDxxYK consensus sequence that binds F-actin. The N-terminal and the C-terminal ends of Nebulin contain unique protein domains. The C-terminal is anchored in the Z-disc of the muscle sarcomere and contains a conserved Src homology (SH3) domain. Although all known exons in the NEB gene can encode a protein with up to 8,525 amino-acids, alternative splicing may produce somewhat smaller proteins. Most of these alternative splicing events simply remove exons from the nebulin mRNAs, however, all nebulin mRNAs contain either exon 143 or exon 144, but never both. Exon 143 codes for amino acids 5242-5272 and exon 144 codes for amino acids 5277-5307. The sequence encoded by exon 143 shows complete homology between mouse, rat, and human. Studies on NEB knockout mice demonstrate a role for nebulin in establishing lateral connectivity of myofibrils and they lose their tight lateral register on stretch. (Ref.: Lam, L., et al. (2018).
