ZNF896,
(Xp11.21), ZXDA,'
Geeni koodaa toista kahdesta kaksinkertaistuneesta sinkkisormigeenistä: Tämä X-kromosomin geeni (Xp11) on telomeerinen kopio ja se, joka on sentromeerismpänä sijaitseva. Ne kaksi geeniä omaavat 98%:sen nukleotidisekvenssien samankaltaisuuden ja oletetut proteiinit sisältävät 10 peräkkäistä sinkkisormimotiivia. Tähän geeniin ZXDA liittyy monokromaattinen sinivärisokeus. Tärkeä paralogi on se toinen geeni ZXDB ( ZNF905, X11.21).
Lisänä tästä geenistä ZNF896 tärkeää tietoa: Sillä on vaikutusta immunologiseen rakenteeseen: Se edistää MHC I ja MHC II luokkien geenitranskriptiota. Proteiinikoko 799 aminohappoa.

Tästä on tietoa on sen oman otsikon alla enemmän:
-
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).
