  1. UNC-54 Caenorhabditis elegans genome Chris Weaver | Bioinformatics | Spring 2008

  2. Introduction • Uncoordinated protein 54 • Also known as: myo-4 (Myosin-4) • UNC-54 is required for locomotion and egg-laying • Gene: F11C3.3 • Transcripts: F11C3.3.1, F11C3.3.2, F11C3.3.3 • Wormbase ID: WBGene00006789

  3. Characteristics • Size • 1963 amino acids • 5892 base pairs • mRNA sequence: 6826 bps • Exons: 11 • Introns: 10 • Location • Chromosome I at location 14,852,479-14,863,527. (2) • The start of this gene is located in Superlink Chromosome I. (2)

  4. Fun facts • Encodes a muscle myosin class II heavy chain (MHC B) • Motor Protein responsible for actin-based mobility • C. Elegan sperm is thought to be the only eukaryotic cell without G-actin. (4) • UNC-54 is a thick filament component that is expressed in multiple muscle cell classes including body wall, intestinal, anal depressor, and sphincter muscles as well as sex-specific muscles • Interacts with ITR-1, an IP3 receptor, and this interaction may provide a link between calcium signaling and the muscle cytoskeleton

  5. Gene ontology • Biological Processes • Body morphogenesis, inositol lipid-mediated signaling, locomotion, muscle contraction (5), muscle thick filament assembly, Oviposition, pharyngeal pumping, positive regulation of locomotion, signal transduction • Cellular component • Intracellular, Muscle myosin complex, Myosin complex • Molecular function • ATP binding, Motor activity, Nucleotide binding, Structural constituent of muscle

  6. Predicted Exon Structure NOTE: Transcript is on (-) strand.

  7. Discovery • Origin: Welcome Trust Sanger Institute, Cambridge UK • Predicted coding sequence & Curated • MacLeod AR, Waterston RH, Brenner S. • Genetic screening (3) • Partially Confirmed with cDNA evidence
