    basic FUNCTION
  • involved in nuclear lamina organization and in the stability and function of rigorously moving nuclei in tissues such as skeletal muscle, heart, joints
  • regulating gene expression in heart and muscle by interacting with specific transcription factors or DNA sequences
  • type II inner nuclear membrane (INM) protein
  • regulate the flux of beta-catenin, an important transcription coactivator, into the nucleus
  • can influence signaling pathways by restricting access of transcription coactivators to the nucleus
  • having functions in cell polarization
  • nuclear-membrane protein with roles in nuclear architecture, gene regulation and signaling
  • having roles as a downstream effector and signal integrator for tyrosine kinase signaling pathway(s) at the nuclear envelope

    INTERACTION
    DNA
    RNA
    small molecule
    protein
  • LMNA, barrier to integration factor (BAF), through the LEM domain
  • interacting with nuclear actin
  • LMO7 positively regulating many EDMD-relevant genes (including emerin)
  • feedback-regulating LMO7
  • molecularly connected with the nuclear lamina, a protein meshwork composed of lamins and lamin-binding proteins underlying the inner nuclear membrane (emerin-prelamin A interplay influences nuclear organization)
  • interacting with SYNE2 (Nesprin-2 and emerin localize to the nuclear enveloppe)
  • binds to and inhibits the activity of LMO7, a transcription factor that regulates the expression of genes implicated in EMD (binding to LMO7 inhibited LMO7 binding to and activation of the MYOD and PAX3 promoters)
  • binds directly to HDAC3, the catalytic subunit of the nuclear co-repressor (NCoR) complex, and recruits HDAC3 to the nuclear periphery

    REGULATION
    Other phosphorylated on serine 49 by protein kinase A
    its function is regulated by multiple tyrosine kinases, including ERBB2, SRC and ABL1, two of which (ERBB2, SRC) regulate striated muscle
