SET and MYND domain containing 1; Methylates histone H3 at ’Lys-4’ (H3K4me), seems able to perform both mono-, di-, and trimethylation. Acts as a transcriptional repressor. Essential for cardiomyocyte differentiation and cardiac morphogenesis (490 aa)

ubiquitin C (685 aa)

SET domain containing 1A; 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-overalpping localization with SETD1B suggests that SETD1A and SETD1B make non-redundant contributions to the epigenetic control of chromatin structure and gene expression (1707 aa)

H3 ’Lys-4’ methylation represents a specific tag for epigenetic transcriptional activation. The non-overalpping localization with SETD1A suggests that SETD1A and SETD1B make non-redundant contributions to the epigenetic control of chromatin structure and gene expression. Specifically tri-methylates ’Lys-4’ of histone H3 in vitro (1923 aa)

bromodomain and PHD finger containing, 3; Component of the MOZ/MORF complex which has a histone H3 acetyltransferase activity (1205 aa)

bromodomain containing 1; Component of the MOZ/MORF complex which has a histone H3 acetyltransferase activity (1058 aa)

suppressor of Ty 5 homolog (S. cerevisiae); Component of the DRB sensitivity-inducing factor complex (DSIF complex), which regulates mRNA processing and transcription elongation by RNA polymerase II. DSIF positively regulates mRNA capping by stimulating the mRNA guanylyltransferase activity of RNGTT/CAP1A. DSIF also acts cooperatively with the negative elongation factor complex (NELF complex) to enhance transcriptional pausing at sites proximal to the promoter. Transcriptional pausing may facilitate the assembly of an elongation competent RNA polymerase II complex. DSIF and NELF promot [...] (1087 aa)

ash2 (absent, small, or homeotic)-like (Drosophila); Component of the Set1/Ash2 histone methyltransferase (HMT) complex, a complex that specifically methylates ’Lys-4’ of histone H3, but not if the neighboring ’Lys-9’ residue is already methylated. As part of the MLL1/MLL complex it is involved in methylation and dimethylation at ’Lys-4’ of histone H3. May function as a transcriptional regulator. May play a role in hematopoiesis (628 aa)
