Anti-SET1/SETD1A Antibody Picoband® Fluoro488 Conjugated

Histone-lysine N-methyltransferase SETD1A is an enzyme that in humans is encoded by the SETD1A gene. It is mapped to 16p11.2. The protein encoded by this gene is a component of a histone methyltransferase (HMT) complex that produces mono-, di-, and trimethylated histone H3 at Lys4. Trimethylation of histone H3 at lysine 4 (H3K4me3) is a chromatin modification known to generally mark the transcription start sites of active genes. The protein contains SET domains, a RNA recognition motif domain and is a member of the class V-like SAM-binding methyltransferase superfamily.

Histone-lysine N-methyltransferase SETD1A; Lysine N-methyltransferase 2F; SET domain-containing protein 1A; Hset1a; Set1/Ash2 histone methyltransferase complex subunit SET1; SETD1A; KIAA0339; KMT2F; SET1; SET1A

Histone methyltransferase that specifically methylates 'Lys-4' of histone H3, when part of the SET1 histone methyltransferase (HMT) complex, but not if the neighboring 'Lys-9' residue is already methylated. H3 'Lys-4' methylation represents a specific tag for epigenetic transcriptional activation. The non-overlapping localization with SETD1B suggests that SETD1A and SETD1B make non-redundant contributions to the epigenetic control of chromatin structure and gene expression.
