Phosphofurin acidic cluster sorting protein 1 also known as PACS-1 is a protein that in humans is encoded by the PACS1 gene.[1][2][3]

Contents

Function

The PACS-1 protein has a putative role in the localization of trans-Golgi network (TGN) membrane proteins. Mouse and rat homologs have been identified and studies of the homologous rat protein indicate a role in directing TGN localization of furin by binding to the protease's phosphorylated cytosolic domain. In addition, the human protein plays a role in HIV-1 Nef-mediated downregulation of cell surface MHC-I molecules to the TGN, thereby enabling HIV-1 to escape immune surveillance.[3]

Interactions

PACS1 has been shown to interact with Furin.[4]
