Protein: Histone-lysine N-methyltransferase SETD1B (EC 2.1.1.364) (SET domain-containing protein 1B) (Q8CFT2)
Organism: Mus musculus (Mouse)
Function: Histone methyltransferase that catalyzes methyl group transfer from S-adenosyl-L-methionine to the epsilon-amino group of 'Lys-4' of histone H3 (H3K4) via a non-processive mechanism. Part of chromatin remodeling machinery, forms H3K4me1, H3K4me2 and H3K4me3 methylation marks at active chromatin sites where transcription and DNA repair take place (By similarity). Plays an essential role in regulating the transcriptional programming of multipotent hematopoietic progenitor cells and lymphoid lineage specification during hematopoiesis.
Subcellular location: Nucleus {ECO:0000269|PubMed:24550110}. Nucleus speckle {ECO:0000250|UniProtKB:Q9UPS6}. Chromosome {ECO:0000250|UniProtKB:Q9UPS6}. Cytoplasm {ECO:0000250|UniProtKB:Q9UPS6}. Note=Localizes to a largely non-overlapping set of euchromatic nuclear speckles with SETD1A, suggesting that SETD1A and SETD1B each bind to a unique set of target genes (By similarity). Predominantly nuclear (By similarity). {ECO:0000250|UniProtKB:Q9UPS6}.
