fibroblast growth factor 4; Plays an important role in the regulation of embryonic development, cell proliferation, and cell differentiation. Required for normal limb and cardiac valve development during embryogenesis (206 aa)

ring finger protein 212; Key regulator of crossing-over during meiosis- required to couple chromosome synapsis to the formation of crossover- specific recombination complexes. Localizes to recombination sites and stabilizes meiosis-specific recombination factors, such as MutS-gamma complex proteins (MSH4 and MSH5) and TEX11. May act as a SUMO E3 ligase that mediates sumoylation of target proteins MSH4 and/or MSH5, leading to enhance their binding to recombination sites. Acts as a limiting factor for crossover designation and/or reinforcement (By similarity) (297 aa)

lysine (K)-specific demethylase 2A; Histone demethylase that specifically demethylates ’Lys- 36’ of histone H3, thereby playing a central role in histone code. Preferentially demethylates dimethylated H3 ’Lys-36’ residue while it has weak or no activity for mono- and tri-methylated H3 ’Lys- 36’. May also recognize and bind to some phosphorylated proteins and promote their ubiquitination and degradation. Required to maintain the heterochromatic state. Associates with centromeres and represses transcription of small non-coding RNAs that are encoded by the clusters of satellite repeats at [...] (1162 aa)

5’-3’ exoribonuclease 1; Major 5’-3’ exoribonuclease involved in mRNA decay. Required for the 5’-3’-processing of the G4 tetraplex-containing DNA and RNA substrates. The kinetic of hydrolysis is faster for G4 RNA tetraplex than for G4 DNA tetraplex and monomeric RNA tetraplex. Binds to RNA and DNA (By similarity). Plays a role in replication-dependent histone mRNA degradation. May act as a tumor suppressor protein in osteogenic sarcoma (OGS) (1706 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)

euchromatic histone-lysine N-methyltransferase 2 (1210 aa)

H2A histone family, member X; Variant histone H2A which replaces conventional H2A in a subset of nucleosomes. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling. Required for checkpoint-mediated arrest of cell cycle progression in resp [...] (143 aa)

HORMA domain containing 2; Essential for synapsis surveillance during meiotic prophase via the recruitment of ATR activity. Plays a key role in the male mid-pachytene checkpoint and the female meiotic prophase checkpoint- required for efficient build-up of ATR activity on unsynapsed chromosome regions, a process believed to form the basis of meiotic silencing of unsynapsed chromatin (MSUC) and meiotic prophase quality control in both sexes. Required for the DNA double-strand break-independent, BRCA1-dependent activation of ATR on the sex chromosomes that is essential for normal sex bod [...] (307 aa)
