Homodimer (PubMed:21151871). Heterodimer with other family members, including GBP1, GBP2, GBP3 and GBP4 (PubMed:21151871). Dimerization is nucleotide-dependent; isoform 1 and isoform 2 form dimers when GTP-bound. GDP-bound isoform 2 is monomeric, while isoform 1 remains dimeric (PubMed:20180847). Dimerization regulates subcellular location. May also form tetramers (dimer of dimers) in the presence of GTP (PubMed:20180847). Interacts with NLRP3, possibly in its tetrameric form, and promotes PYCARD/ASC polymerization (PubMed:22461501).
