retinoblastoma binding protein 5; In embryonic stem (ES) cells, plays a crucial role in the differentiation potential, particularly along the neural lineage, regulating gene induction and H3 ’Lys-4’ methylation at key developmental loci, including that mediated by retinoic acid (By similarity). As part of the MLL1/MLL complex, involved in mono-, di- and trimethylation at ’Lys-4’ of histone H3. Histone H3 ’Lys-4’ methylation represents a specific tag for epigenetic transcriptional activation (538 aa)

myeloid/lymphoid or mixed-lineage leukemia 2; Histone methyltransferase. Methylates ’Lys-4’ of histone H3 (H3K4me). H3K4me represents a specific tag for epigenetic transcriptional activation. Acts as a coactivator for estrogen receptor by being recruited by ESR1, thereby activating transcription (5537 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)

SMAD family member 3 (425 aa)

catenin (cadherin-associated protein), beta 1, 88kDa; Key downstream component of the canonical Wnt signaling pathway. In the absence of Wnt, forms a complex with AXIN1, AXIN2, APC, CSNK1A1 and GSK3B that promotes phosphorylation on N-terminal Ser and Thr residues and ubiquitination of CTNNB1 via BTRC and its subsequent degradation by the proteasome. In the presence of Wnt ligand, CTNNB1 is not ubiquitinated and accumulates in the nucleus, where it acts as a coactivator for transcription factors of the TCF/LEF family, leading to activate Wnt responsive genes. Involved in the regulation [...] (781 aa)

Histone-lysine N-methyltransferase MLL4 ; Histone methyltransferase. Methylates ’Lys-4’ of histone H3. H3 ’Lys-4’ methylation represents a specific tag for epigenetic transcriptional activation. Plays a central role in beta-globin locus transcription regulation by being recruited by NFE2. Plays an important role in controlling bulk H3K4me during oocyte growth and preimplantation development. Required during the transcriptionally active period of oocyte growth for the establishment and/or maintenance of bulk H3K4 trimethylation (H3K4me3), global transcriptional silencing that preceeds r [...] (2715 aa)

SMAD family member 2; Receptor-regulated SMAD (R-SMAD) that is an intracellular signal transducer and transcriptional modulator activated by TGF-beta (transforming growth factor) and activin type 1 receptor kinases. Binds the TRE element in the promoter region of many genes that are regulated by TGF-beta and, on formation of the SMAD2/SMAD4 complex, activates transcription. May act as a tumor suppressor in colorectal carcinoma. Positively regulates PDPK1 kinase activity by stimulating its dissociation from the 14-3-3 protein YWHAQ which acts as a negative regulator (467 aa)

nuclear factor of kappa light polypeptide gene enhancer in B-cells 1; NF-kappa-B is a pleiotropic transcription factor present in almost all cell types and is the endpoint of a series of signal transduction events that are initiated by a vast array of stimuli related to many biological processes such as inflammation, immunity, differentiation, cell growth, tumorigenesis and apoptosis. NF-kappa-B is a homo- or heterodimeric complex formed by the Rel-like domain-containing proteins RELA/p65, RELB, NFKB1/p105, NFKB1/p50, REL and NFKB2/p52 and the heterodimeric p65-p50 complex appears to b [...] (969 aa)
