General annotation (Comments)
| Function | Histone methyltransferase. Methylates 'Lys-4' of histone H3. H3 'Lys-4' methylation represents a specific tag for epigenetic transcriptional activation. Ref.10 |
| Catalytic activity | S-adenosyl-L-methionine + histone L-lysine = S-adenosyl-L-homocysteine + histone N(6)-methyl-L-lysine. Ref.10 |
| Subunit structure | Component of the MLL3/MLL4 complex, at least composed of MLL3, MLL4, ASH2L, RBBP5, DPY30, WDR5, NCOA6, KDM6A (or KDM6B), PAXIP1/PTIP and C16orf53/PA1. |
| Subcellular location | Nucleus By similarity. |
| Tissue specificity | Widely expressed. Highest levels in testis. Also found in brain, bone marrow, heart, muscle, kidney, pancreas, spleen, thymus, prostate, ovary, intestine, colon, peripheral blood lymphocytes, and placenta. |
| Post-translational modification | Phosphorylated upon DNA damage, probably by ATM or ATR By similarity. |
| Involvement in disease | Often amplified in pancreatic carcinomas. |
| Sequence similarities | Belongs to the histone-lysine methyltransferase family. TRX/MLL subfamily. Contains 3 A.T hook DNA-binding domains. Contains 1 CXXC-type zinc finger. Contains 3 PHD-type zinc fingers. Contains 1 post-SET domain. Contains 1 SET domain. |
| Caution | This protein was first named MLL2 by Ref.3 and Ref.6. MLL2 corresponds to another protein located on chromosome 12 (see AC O14686). |
