== Function ==
 +
[https://www.uniprot.org/uniprot/WDR5_HUMAN WDR5_HUMAN] Contributes to histone modification. May position the N-terminus of histone H3 for efficient trimethylation at 'Lys-4'. As part of the MLL1/MLL complex it is involved in methylation and dimethylation at 'Lys-4' of histone H3. H3 'Lys-4' methylation represents a specific tag for epigenetic transcriptional activation. As part of the NSL complex it may be involved in acetylation of nucleosomal histone H4 on several lysine residues. May regulate osteoblasts differentiation.<ref>PMID:19556245</ref> <ref>PMID:19103755</ref> <ref>PMID:20018852</ref> <ref>PMID:16600877</ref> <ref>PMID:16829960</ref>

== Publication Abstract from PubMed ==
 +
The WD40-repeat protein WDR5 is a conserved subunit of Trithorax (TRX) histone methyltransferase complexes. WDR5 has been reported to selectively bind dimethylated Lys4 (K4me2) in histone H3 to promote K4 trimethylation by TRX. To elucidate the basis of this binding specificity, we have determined the crystal structure of WDR5 bound to a histone H3 peptide bearing K4me2. The structure reveals that the N terminus of histone H3 binds as a 3(10)-helix in the central depression formed by the WD40 repeats. R2 in histone H3 is bound in the acidic channel in the protein's core, whereas K4me2 is solvent exposed and does not engage in direct interactions with WDR5. Functional studies confirm that WDR5 recognizes A1, R2 and T3 in histone H3 but has virtually identical affinities for the unmodified and mono-, di- and trimethylated forms of K4, demonstrating that it does not discriminate among different degrees of methylation of this residue.
