Tirozinska proteinska kinaza CSK (C-Src kinaza, C-terminalna Src kinaza) enzim je koji je kod ljudi kodiran CSK genom.[1] Ovaj enzim fosforilizuje tirozinske ostatke locirane na C-terminalnom kraju Src familije kinaza (SFK) uključujući SRC, HCK, FYN, LCK, LYN i YES1.[2][3]
Funkcija[uredi | uredi kod]
Tirozinska proteinska kinaza CSK supresuje dejstvo Src familije proteinskih kinaza putem fosforilacije članova Src familije na konuerviranom C-terminalnom mestu u Src.[4][5][6][7] Za Csk kontrolu dejstva Src familije se smatra da ima centralno mesto u regulaciji imunskog responsa.[8] Src takođe reguliše angiogene faktore i vaskularnu permeabilnost nakon fokalne cerebralne ischemijske reperfuzije.[9][10]
Klinički značaj[uredi | uredi kod]
Csk interakcija sa fosfatazom ("Lyp", genski produkt PTPN22) acociran je sa povišenom zastupljenošću autoimunskih bolesti vezanih za PTPN22 mutacije.[11]
