SRGN

Serglicin, znan i kao hematopoietski proteoglikanski jezgreni protein ili proteoglikanski jezgreni protein sekrecijskih granula, jest protein koji je kod ljudi kodiran genom SRGN. It is primarily expressed in hematopoietic cells and endothelial cells, and is the only known intracellular proteoglycan.

Funkcija

Ovaj gen kodira protein najpoznatiji kao hematopoetska ćelija proteoglikanskih granula. Proteoglikani pohranjeni u sekrecijskim granulama mnogih hematopoetskih ćelija također sadrže peptidno jezgro otporno na proteazu, koja može biti važna za neutraliziranje hidrolitiskih enzima. Utvrđeno je da je ovaj kodirani protein povezan s makromolekulnim kompleksom granzima i perforina, koji može poslužiti kao posrednik apoptoza posredovanih granulama.
