This entry represents the G-like (guanine nucleotide-binding domain) domain, found in Tsr1, a protein required for normal export of the pre-40S particles from the nucleus to the cytoplasm during 40S ribosomal subunit synthesis [1-5]. This domain adopts a GTPase-like fold, but lacks a P-loop and is not predicted to bind GTP.	Domain
