Recombinant Human Histone-lysine N-methyltransferase SETD1B (SETD1B), Truncated

Target Species

Human

Target Name

SETD1B

Target Full Name

Histone-lysine N-methyltransferase SETD1B

Target 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. Plays an essential role in regulating the transcriptional programming of multipotent hematopoietic progenitor cells and lymphoid lineage specification during hematopoiesis.

Target Subcellular Location

Nucleus speckle. Chromosome. Note=Localizes to a largely non-overlapping set of euchromatic nuclear speckles with SETD1A, suggesting that SETD1A and SET1B each bind to a unique set of target genes.

Target Protein Families

Class V-like SAM-binding methyltransferase superfamily

Target Synonyms

FLJ20803; Histone-lysine N-methyltransferase SETD1B; hSET1B; KIAA1076; KMT2G; Lysine N-methyltransferase 2G; SET domain containing 1B; SET domain-containing protein 1B; SET1B; SET1B_HUMAN; SETD1B

Target Background

SET1B is a component of a histone methyltransferase complex that produces trimethylated histone H3 at Lys4 (Lee et al., 2007 [PubMed 17355966]).
