    PHYSICAL PROPERTIES
    STRUCTURE
    motifs/domains
  • a conserved MYND zinc finger involved in recruitement of HDAC and transcriptional repression, and that may primarily serve as a protein interaction module and cooperate SMYD1 with NACA to regulate cardiomyocyte growth and maturation
  • a "split" SET domain,
  • a novel C-terminal domain (CTD) that distinguishes SMYD1 from other SET domain containing methyltransferases
  • HOMOLOGY
    interspecies homolog to murine Bop
    Homologene
    FAMILY

    basic FUNCTION
  • involved in cardiomyocyte differentiation and chamber-specific development
  • acting as a histone deacetylase-dependent transcriptional repressor
  • involved in cardiovascular development and transcriptional regulation
  • may be playing a critical role in myofibril organization during myofiber maturation
  • regulator of right ventricular heart development
  • essential downstream effector gene of MEF2C in the developing heart
  • key regulator of myogenic differentiation, acting as a downstream target of muscle regulatory factors SRF and myogenin
  • cardiac- and muscle-specific histone methyltransferase that methylates histone H3 at lysine 4 and regulates gene transcription in early heart development
  • muscle-restricted histone methyltransferase, essential for cardiogenesis and functions with a network of cardiac regulatory proteins
  • essential role for the SMYD1-myosin interaction in cardiac and fast-twitch skeletal muscle thick filament assembly
  • CELLULAR PROCESS nucleotide, transcription, regulation

    INTERACTION
    DNA
    RNA
    small molecule
    protein
  • interacting with HDGF
  • direct transcriptional target of MEF2C in the developing heart (SMYD1 expression in the developing heart depends on the direct binding of MEF2C to a MEF2-response element in the Bop promoter)
  • NACA is the major binding partner for SMYD1 in the developing heart
  • cell & other
    REGULATION
    repressed by HDGF, through interaction with a transcriptional corepressor C-terminal binding protein CTBP1, and CTBP2
    Other appears to be regulated by an autoinhibition mechanism
