Function

GBP1_HUMAN Hydrolyzes GTP to GMP in two consecutive cleavage reactions. Exhibits antiviral activity against influenza virus. Promote oxidative killing and deliver antimicrobial peptides to autophagolysosomes, providing broad host protection against different pathogen classes.^[1]

Publication Abstract from PubMed

Interferon-gamma is an immunomodulatory substance that induces the expression of many genes to orchestrate a cellular response and establish the antiviral state of the cell. Among the most abundant antiviral proteins induced by interferon-gamma are guanylate-binding proteins such as GBP1 and GBP2. These are large GTP-binding proteins of relative molecular mass 67,000 with a high-turnover GTPase activity and an antiviral effect. Here we have determined the crystal structure of full-length human GBP1 to 1.8 A resolution. The amino-terminal 278 residues constitute a modified G domain with a number of insertions compared to the canonical Ras structure, and the carboxy-terminal part is an extended helical domain with unique features. From the structure and biochemical experiments reported here, GBP1 appears to belong to the group of large GTP-binding proteins that includes Mx and dynamin, the common property of which is the ability to undergo oligomerization with a high concentration-dependent GTPase activity.
