Bms1, an essential GTPase, promotes assembly of preribosomal RNA processing complexes; Bms1 is an essential, evolutionarily conserved, nucleolar protein. Its depletion interferes with processing of the 35S pre-rRNA at sites A0, A1, and A2, and the formation of 40S subunits. Bms1, the putative endonuclease Rc11, and the essential U3 small nucleolar RNA form a stable subcomplex that is believed to control an early step in the formation of the 40S subumit. The C-terminal domain of Bms1 contains a GTPase-activating protein (GAP) that functions intramolecularly. It is believed that Rc11 activates Bms1 by acting as a guanine-nucleotide exchange factor (GEF) to promote GDP/GTP exchange, and that activated (GTP-bound) Bms1 delivers Rc11 to the preribosomes.

40S ribosome biogenesis protein Tsr1 and BMS1 C-terminal; RIBIOP_C is a family of eukaryotic proteins from the C-terminus of pre-rRNA-processing protein or ribosome biogenesis proteins BMS1 and TSR1. These proteins act, in the nucleolus, as a molecular switch during maturation of the 40S ribosomal subunit. This domain, domain IV of translation elongation factor selb, adopts the same fold as translation proteins such as domain II of GTP-elongation factor Tu proteins.

GTP translation factor family primarily contains translation initiation, elongation and release factors; The GTP translation factor family consists primarily of translation initiation, elongation, and release factors, which play specific roles in protein translation. In addition, the family includes Snu114p, a component of the U5 small nuclear riboprotein particle which is a component of the spliceosome and is involved in excision of introns, TetM, a tetracycline resistance gene that protects the ribosome from tetracycline binding, and the unusual subfamily CysN/ATPS, which has an unrelated function (ATP sulfurylase) acquired through lateral transfer of the EF1-alpha gene and development of a new function.

of the residues that compose this conserved feature have been mapped to the query sequence.
Click on the triangle to view details about the feature, including a multiple sequence alignment
of your query sequence and the protein sequences used to curate the domain model,
where hash marks (#) above the aligned sequences show the location of the conserved feature residues.
The thumbnail image, if present, provides an approximate view of the feature's location in 3 dimensions.

This image shows a graphical summary of conserved domains identified on the query sequence.
The Show Concise/Full Display button at the top of the page can be used to select the desired level of detail: only top scoring hits
(labeled illustration) or all hits
(labeled illustration).
Domains are color coded according to superfamilies
to which they have been assigned. Hits with scores that pass a domain-specific threshold
(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.
click on the bars or triangles to view your query sequence embedded in a multiple sequence alignment of the proteins used to develop the corresponding domain model.
The table lists conserved domains identified on the query sequence. Click on the plus sign (+) on the left to display full descriptions, alignments, and scores.
Click on the domain model's accession number to view the multiple sequence alignment of the proteins used to develop the corresponding domain model.
To view your query sequence embedded in that multiple sequence alignment, click on the colored bars in the Graphical Summary portion of the search results page,

Concise Display shows only the best scoring domain model, in each hit category listed below except non-specific hits, for each region on the query sequence.

(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:
specific hits meet or exceed a domain-specific e-value threshold
(illustrated example)
and represent a very high confidence that the query sequence belongs to the same protein family as the sequences use to create the domain model
non-specific hits
meet or exceed the RPS-BLAST threshold for statistical significance (default E-value cutoff of 0.01, or an E-value selected by user via the
