Funkcija

uredi

Ovaj gen kodira člana porodice Ser/Thr protein kinaze. Ova kinaza regulirana je direktnom fosforilacijom, pomoću p38 MAP-kinaza. Poznato je da je, zajedno sa p38 MAP-kinazom, ova kinaza uključena u mnoge ćelijske procese, kao što su stres i upalne odgovore, jedarni eksport, regulaciju ekspresije gena i proliferaciju ćelija. Pokazalo se da je protein toplotnog šoka HSP27 njegov glavni direktni supstrat in vivo. Za ovaj gen su pronađene dvije varijante transkripta koje kodiraju dvije različite izoforme.[9]

Vaskularna barijera

uredi

Pokazalo se da put MK2 ima ključnu ulogu u održavanju i popravljanju integriteta endotelne barijere u plućima putem aktina [10] i remodeliranja vimentina. Pokazalo se da aktivacija MK2 putem njegove fosforilacije pomoću p38 obnavlja vaskularnu barijeru[7] i popravlja vaskularno curenje,[11] povezano sa preko 60 medicinskih stanja, uključujući sindrom akutnog respiratornog distresa (ARDS), glavnog uzroka smrti širom svijeta.[12]

Inicijacija SASP-a

uredi

MAPKAPK2 posreduje u inicijaciji sekretornog fenotipa vezanog za starenje (SASP), pomoću mTOR (mehanička meta rapamicina).[13][14] Interleukin 1 alfa (IL1A) nalazi se na površini senescentnih ćelija, gdje doprinosi proizvodnji SASP faktora zbog pozitivne povratne petlje sa NF-κB.[15][16] Translacija iRNK za IL1A u velikoj mjeri ovisi o aktivnosti mTOR-a.[17] Aktivnost mTOR povećava nivoe IL1A, posredovane putem MAPKAPK2.[15]
