Comments
  • FUNCTION: Strong transcriptional activator; DNA-binding protein that specifically recognize the sequence 5'-YAAC[GT]G-3'. Could have a role in the proliferation and/or differentiation of neurogenic, spermatogenic and B-lymphoid cells.
  • SUBUNIT: Component of the DREAM complex (also named LINC complex) at least composed of E2F4, E2F5, LIN9, LIN37, LIN52, LIN54, MYBL1, MYBL2, RBL1, RBL2, RBBP4, TFDP1 and TFDP2. The complex exists in quiescent cells where it represses cell cycle-dependent genes. It dissociates in S phase when LIN9, LIN37, LIN52 and LIN54 form a subcomplex that binds to MYBL2.
  • SUBCELLULAR LOCATION: Nucleus.
  • TISSUE SPECIFICITY: Expressed in a variety of lymphoid and solid tumor lines cultured in vitro.
  • SIMILARITY: Contains 3 HTH myb-type DNA-binding domains.
  • WEB RESOURCE: Name=Atlas of Genetics and Cytogenetics in Oncology and Haematology; URL="http://atlasgeneticsoncology.org/Genes/MYBL1ID41468ch8q13.html";.
