Angiopoietinski receptori su receptori za koje se vezuje angiopoietin.

TIE-1 i TIE-2 su receptori na ćelijskoj površini koji se aktiviraju vezivanjem angiopoietina, (Ang1, Ang2, Ang3, Ang4). Angiopoietini su proteinski faktori rasta koji su neophodni za formiranje krvnih sudova (angiogenezu).[1]

Angiopoietini

[uredi | uredi kod]

Angiopoietini su proteinski faktori rasta koji pospešuju angiogenezu, formiranje krvnih sudova. Poznata su četiri angiopoietina: Ang1, Ang2, Ang3, Ang4. Ang1 i Ang4 deluju kao agonistički i aktivirajući ligandi za Tie2, dok su Ang2 i Ang3 kompetitivni antagonisti. Oni se vezuju za Tie-1 i Tie-2. Ovi receptori su tirozinske kinaze koji posreduju prenos signala indukovanjem fosforilacije ključnih tirozina, čime iniciraju proces ćelijske signalizacije.
