PROTEIN
PHYSICAL PROPERTIES
STRUCTURE
motifs/domains
  • a NAC domain, with a region as a new nucleic acid-binding region, which is blocked from binding nucleic acids in the heterodimeric complex by a helix region in the beta-subunit
  • mono polymer heteromer , dimer

    basic FUNCTION
  • transcriptional coactivator, preventing inappropriate targeting of non-secretory polypeptides to the endoplasmic
  • reticulum (ER)
  • cytokine-modulated specific transcript in the human TF-1 erythroleukemic cell line
  • is a new factor involved in the positive regulation of human erythroid-cell differentiation
  • may act as a specific coactivator for JUN, binding to DNA
  • and stabilizing the interaction of JUN homodimers with target gene promoters
  • participates in the proper maturation of newly synthesized proteins
  • its degradation triggers ER stress responses and initiates apoptotic processes in hypoxic cells, and GSK3B may participate upstream in this mechanism
  • plays potentially a critical role in ventricular cardiomyocyte expansion and regulates postnatal skeletal muscle growth and regeneration
  • plays a role in regulating gene transcription during mesenchymal cell differentiation by differentially recruiting corepressors at target promoters
  • controls myoblast migration and sarcomere architecture in a calpain-dependent manner
  • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
    a component
  • complexing with newly synthesized polypeptide chains
  • heterodimer, and its two subunits form a stable complex through a dimerizing domain called the NAC domain
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • interacts with TBP and JUN
  • NACA may serve as an intracellular regulator of FADD function
  • is the major binding partner for SMYD1 in the developing heart
  • functional interaction between ATF4, TXLNG, and NACA, three proteins that have been previously shown to associate using various protein-protein interaction assays
  • acts as a transcriptional coactivator of the Osteocalcin gene
  • inhibition of NACA gene expression leads to enhanced, and overexpression of NACA gene to repressed, activity of CAPN1 and, to a lesser extent, CAPN3 in myoblasts
