ARB1

ATP-binding cassette family ATPase ARB1, YER036C
ATPase of the ATP-binding cassette (ABC) family; involved in 40S and 60S ribosome biogenesis, has similarity to Gcn20p; shuttles from nucleus to cytoplasm, physically interacts with Tif6p, Lsg1p

DED1

SPP81, DEAD-box ATP-dependent RNA helicase DED1, L000000500, YOR204W
ATP-dependent DEAD (Asp-Glu-Ala-Asp)-box RNA helicase; required for translation initiation of all yeast mRNAs; binds to mRNA cap-associated factors, and binding stimulates Ded1p RNA-dependent ATPase activity; mutation in human homolog DBY is associated with male infertility; human homolog DDX3X complements ded1 null mutation; DED1 has a paralog, DBP1, that arose from the whole genome duplication

Affinity Capture-MS

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner is identified by mass spectrometric methods.

Publication

The novel ATP-binding cassette protein ARB1 is a shuttling factor that stimulates 40S and 60S ribosome biogenesis.

Dong J, Lai R, Jennings JL, Link AJ, Hinnebusch AG

ARB1 is an essential yeast protein closely related to members of a subclass of the ATP-binding cassette (ABC) superfamily of proteins that are known to interact with ribosomes and function in protein synthesis or ribosome biogenesis. We show that depletion of ARB1 from Saccharomyces cerevisiae cells leads to a deficit in 18S rRNA and 40S subunits that can be attributed ... [more]

Affinity Capture-Western

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner identified by Western blot with a specific polyclonal antibody or second epitope tag. This category is also used if an interacting protein is visualized directly by dye stain or radioactivity. Note that this differs from any co-purification experiment involving affinity capture in that the co-purification experiment involves at least one extra purification step to get rid of potential contaminating proteins.
