  • co-localizes with lamin A and C in the nuclear envelope, and also co-localizes with promyelocytic leukemia (PML) bodies within the nucleus
  • majority of MLIP is localized to the nuclear envelope and within the nucleus itself
    • basic FUNCTION
  • may serve important biological roles in regulating lamin function that includes important roles in maintaining nuclear structure, chromatin organization, DNA replication, cell cycle regulation, and apoptosis
  • likely to contribute to the mesenchymal phenotypes of laminopathies
  • may represent an innovation of amniotes, an amniote acquisition that may play an important regulatory or functional role that is unique to amniotes
  • may function as a tethering protein linking LMNA to unidentified factors either within the nuclear envelope or within PML bodies

  • interacts directly and co-localizes with lamin A and C in the nuclear envelope
  • interaction with LMNA, and MLIP interaction domain is between AAs 1 and 130 of LMNA, which includes the N-terminal globular head domain plus coil 1A, linker 1, and the first 43 AAs of coil 1B
