    at STAGE
  • 23 N terminal actin-binding repeats of 35 residues (S2XXYK consensus sequence)
  • a serine rich domain with potential phosphorylation sites
  • a C terminal SH3 domain, that is novel ligand of proline-rich regions of XIRP1 and XIRP2
    interspecies homolog to murine Lasp2
    intraspecies homolog to extremely similar to the C terminus of nebulin
    FAMILY LASP family proteins, nebulin family of actin binding proteins.
    CATEGORY motor/contractile , structural protein
  • binding the Z band to actin filaments
  • C terminal integrating into the Z disc lattice and a N terminus projecting into the I-band
  • basic FUNCTION
  • playing an important role in the assembly of the Z- disc
  • may play an important role in the organization of focal adhesions with LASP1, and zyxin
  • LASP1 and NEBL, are important during early embryo- and fetogenesis and are highly expressed in the central nervous system of the adult
  • dynamic focal adhesion protein that increases the rate of attachment and spreading of fibroblasts on fibronectin coated surfaces
  • NEBL and LASP1 have distinct roles in the actin cytoskeleton
  • cardiac-specific isoform of the giant actin-binding protein nebulin
  • has an important role in coordinating and regulating the composition and dynamics of focal adhesions
  • sarcomeric Z-disk protein involved in mechanosensing and force generation via its interaction with actin and tropomyosin-troponin complex
    a component
    small molecule
  • actin binding
  • interacting with LASP1 and ZYX (SH3 domains from LASP1 and nebulin can also interact with zyxin, but the SH3 domains from more distantly related proteins such as vinexin and SNX9 do not)
  • importance of the NEBL-TPM1 interactions in the maintenance and stability of the thin filaments
  • interplay between LASP2 and LASP1 could be an adhesion regulatory mechanism
  • temporally restricted interaction of Xin-repeat proteins (XIRP1, XIRP2) with nebulin/nebulette during early stages of myofibril development that is lost upon further maturation

  • to endocardial fibroelastosis
  • Variant & Polymorphism SNP
  • N654K, homozygotes KK susceptibility
  • different mutations in NEBL trigger specific mechanisms, converging to a common pathological cascade leading to endocardial fibroelastosis and DCM
  • Candidate gene
  • effects of NEBL mutations on sarcomere ultrastructure, cellular contractile function, and calcium homeostasis in preclinical dilated cardiomyopathy (DCM), suggesting that these abnormalities correlate with detectable myocardial wall motion patterns
