Myeloid/Lymphoid Or Mixed Lineage Leukemia 3 (MLL3)

MLL3 is a member of the myeloid/lymphoid or mixed-lineage leukemia (MLL) family and encodes a nuclear protein with an AT hook DNA-binding domain, a DHHC-type zinc finger, six PHD-type zinc fingers, a SET domain, a post-SET domain and a RING-type zinc finger. This protein is a member of the ASC-2/NCOA6 complex (ASCOM), which possesses histone methylation activity and is involved in transcriptional coactivation. MLL3 has 6 plant homeodomain (PHD) fingers preceded by a cys-rich ZNF1 domain in its N terminus; a high mobility group (HMG) box, an ATPase alpha-beta signature, and a leucine zipper motif in its central region; and 2 C-terminal FY (phe-tyr) motifs and a SET domain preceded by a ZNF2 domain in its C terminus. The predicted protein also contains several putative nuclear localization motifs.
