UniprotKB/SwissProt ID: Q8BVE8 (Q8BVE8)
Gene Name:
Nsd2
Organism: Mus musculus (Mouse)
Function: Histone methyltransferase which specifically dimethylates nucleosomal histone H3 at 'Lys-36' (H3K36me2) (PubMed:19483677, PubMed:31636135, PubMed:32862441). Also monomethylates nucleosomal histone H3 at 'Lys-36' (H3K36me) in vitro (PubMed:19483677). Does not trimethylate nucleosomal histone H3 at 'Lys-36' (H3K36me3) (By similarity). However, specifically trimethylates histone H3 at 'Lys-36' (H3K36me3) at euchromatic regions in embryonic stem (ES) cells (PubMed:19483677). By methylating histone H3 at 'Lys-36', involved in the regulation of gene transcription during various biological processes (PubMed:19483677, PubMed:23241889, PubMed:31636135, PubMed:32862441). In ES cells, associates with developmental transcription factors such as SALL1 and represses inappropriate gene transcription mediated by histone deacetylation (PubMed:19483677). During heart development, associates with transcription factor NKX2-5 to repress transcription of NKX2-5 target genes (PubMed:19483677). Plays an essential role in adipogenesis, by regulating expression of genes involved in pre-adipocyte differentiation (By similarity). During T-cell receptor (TCR) and CD28-mediated T-cell activation, promotes the transcription of transcription factor BCL6 which is required for follicular helper T (Tfh) cell differentiation (PubMed:31636135). During B-cell development, required for the generation of the B1 lineage (PubMed:32862441). During B2 cell activation, may contribute to the control of isotype class switch recombination (CRS), splenic germinal center formation, and the humoral immune response (PubMed:32862441). Plays a role in class switch recombination of the immunoglobulin heavy chain (IgH) locus during B-cell activation (PubMed:23241889). By regulating the methylation of histone H3 at 'Lys-36' and histone H4 at 'Lys-20' at the IgH locus, involved in TP53BP1 recruitment to the IgH switch region and promotes the transcription of IgA (PubMed:23241889) Histone methyltransferase which specifically dimethylates nucleosomal histone H3 at 'Lys-36' (H3K36me2) (By similarity). Mono-, di- and tri-methylates histone H3 at 'Lys-27' (H3K27me, H3K27me2, H3K27me3) (PubMed:18172012). Methylation of histone H3 at 'Lys-27' is controversial (By similarity). May act as a transcription regulator that binds DNA and suppresses IL5 transcription through HDAC recruitment (PubMed:18172012)
