ZNF899, (5p14.2), PRDM9, PR/SET domain 9

Tämä sinkkisormiproteiini  (ZNF899) on  tärkeä meioosin profaasissa, sillä se pystyy metyloimaan histoni3 proteiinin lysiini numero K4 ja asettamaan siihen  kolmannen metyyliryhmn. tuote siis on H3K4m3. Siis  se on histonimetyylitransferaasi. Se on H3-K4 spesifinen. tällä proteiinilla on monta erilaista  domeenia, muta  sinkkisormidomeeni ( tyyppiä C2H2) on tärkeä, koska se tunnistaa tuon spesifisen kohdan, johon pitää asettaa   se metyyli. Koska   tällä sinkkisormiproteiinilla on  monta  domeenia, sillä on erilaisia nimiä eikä vain tämä  sinkkisormiryhmän  numeronsa.

Tähän geeniin liittyvinä tauteina tunnetaan velokardiofakiaalinen oireyhtymä ja Hayerhillin kuume (streptobasilloosi, rotanpuremakuume). .

 The protein encoded by this gene is a zinc finger protein with histone methyltransferase activity that catalyzes histone H3 lysine 4 trimethylation (H3K4me3) during meiotic prophase. This protein contains multiple domains, including a Kruppel-associated box (KRAB) domain, an SSX repression domain (SSXRD), a PRD1-BF1 and RIZ homologous region, a subclass of SET (PR/SET) domain, and a tandem array of C2H2 zinc fingers. The zinc finger array recognizes a short sequence motif, leading to local H3K4me3, and meiotic recombination hotspot activity. The observed allelic variation alters the DNA-binding sequence specificity of the protein, resulting in distinct meiotic recombination hotspots amongst individuals and populations. Multiple alternate alleles of this gene have been described. [provided by RefSeq, Jul 2015]
Diseases associated with PRDM9 include Velocardiofacial Syndrome and Haverhill Fever. Among its related pathways are Meiosis and PKMTs methylate histone lysines. Gene Ontology (GO) annotations related to this gene include nucleic acid binding and histone methyltransferase activity (H3-K4 specific). An important paralog of this gene is ZNF343. Size: 894 amino acids Quaternary structure: Homodimer (PubMed:26833727, PubMed:24095733, Ref.9). Interacts with EHMT2 and CDYL; interaction only takes place when PRDM9 is bound to hotspot DNA. Interacts with CXXC1; this interaction does not link PRDM9-activated recombination hotspot sites with DSB machinery and is not required for the hotspot recognition pathway. Forms a complex with EWSR1, REC8, SYCP3 and SYCP1; complex formation is dependent of phosphorylated form of REC8 and requires PRDM9 bound to hotspot DNA; EWSR1 joins PRDM9 with the chromosomal axis through REC8 (By similarity).

UniProtKB/Swiss-Prot Summary for CIITA Gene

  • Essential for transcriptional activity of the HLA class II promoter; activation is via the proximal promoter. No DNA binding of in vitro translated CIITA was detected. May act in a coactivator-like fashion through protein-protein interactions by contacting factors binding to the proximal MHC class II promoter, to elements of the transcription machinery, or both. Alternatively it may activate HLA class II transcription by modifying proteins that bind to the MHC class II promoter. Also mediates enhanced MHC class I transcription; the promoter element requirements for CIITA-mediated transcription are distinct from those of constitutive MHC class I transcription, and CIITA can functionally replace TAF1 at these genes. Activates CD74 transcription (PubMed:32855215). Exhibits intrinsic GTP-stimulated acetyltransferase activity. Exhibits serine/threonine protein kinase activity: can phosphorylate the TFIID component TAF7, the RAP74 subunit of the general transcription factor TFIIF, histone H2B at 'Ser-37' and other histones (in vitro). Has antiviral activity against Ebola virus and coronaviruses, including SARS-CoV-2. Induces resistance by up-regulation of the p41 isoform of CD74, which blocks cathepsin-mediated cleavage of viral glycoproteins, thereby preventing viral fusion (PubMed:32855215).
