ZNF683, (1p36.11). immuunikudos- T-solun transkription säätelijä Hobit

 Hobit, kudoksessa sijaitseva t-solutranskriptiota säätelevä sinkkisormiproteiini ZNF689, ZNF638 (1p36.11),


 Tapasin tänään uuden sinkkisormiproteiinin ZNF683 , kun luin  uudesta   diagnostisesta menetelmästä Viral-Track , jolla voidaan  tutkia COVID-19 potilaiden keuhkohuuhtelunäytteiden  kudos ja immuunisolujen  tilannetta, ovatko ne  infektoituneita viruksesta vai bystander-soluja.  Menetelmässä voidaan erottaa lievää COVID-19 tautia ja vaikeaa tautimuotoa  sairastavien soluprofiilit.   COVID--19 infektiossa lymfoidisissa  soluissa tavataan  CD8+ solujen yhteydessä  ZNF683 sinkkisormiproteiinia. lievemmän  tautimuodon merkitsijänä.

Katson lisäietoa tästä sinkkisormiproteiinista.

   GeneCards Summary for ZNF683 GeneZNF683 (Zinc Finger Protein 683) is a Protein Coding gene. An important paralog of this gene is ZBTB49.
  • Transcription factor that mediates a transcriptional program in various innate and adaptive immune tissue-resident lymphocyte T-cell types such as tissue-resident memory T (Trm), natural killer (trNK) and natural killer T (NKT) cells and negatively regulates gene expression of proteins that promote the egress of tissue-resident T-cell populations from non-lymphoid organs. Plays a role in the development, retention and long-term establishment of adaptive and innate tissue-resident lymphocyte T cell types in non-lymphoid organs, such as the skin and gut, but also in other nonbarrier tissues like liver and kidney, and therefore may provide immediate immunological protection against reactivating infections or viral reinfection. Plays also a role in the differentiation of both thymic and peripheral NKT cells. Negatively regulates the accumulation of interferon-gamma (IFN-gamma) in NKT cells at steady state or after antigenic stimulation. Positively regulates granzyme B production in NKT cells after innate stimulation. Associates with the transcriptional repressor PRDM1/BLIMP1 to chromatin at gene promoter regions.
    • [Isoform 1]: Lacks transcriptional repressor activity. Binds to DNA within promoter regions of the transcriptional repressor PRDM1/BLIMP1 target sites. Unable to regulate interferon-gamma (IFN-gamma) production in cytomegalovirus (CMV)-infected effector CD8(+) T-cells.
    • [Isoform 2]: Transcriptional repressor that binds to DNA within promoter regions of the transcriptional repressor PRDM1/BLIMP1 target sites. Regulates interferon-gamma (IFN-gamma) production in cytomegalovirus (CMV)-infected effector CD8(+) T cells.
