SSB2
YG103, Hsp70 family ATPase SSB2, L000002715, YNL209W
Cytoplasmic ATPase that is a ribosome-associated molecular chaperone; functions with J-protein partner Zuo1p; may be involved in the folding of newly-synthesized polypeptide chains; member of the HSP70 family; SSB2 has a paralog, SSB1, that arose from the whole genome duplication

Co-purification
An interaction is inferred from the identification of two or more protein subunits in a purified protein complex, as obtained by classical biochemical fractionation or affinity purification and one or more additional fractionation steps.

The cotranslational function of ribosome-associated Hsp70 in eukaryotic protein homeostasis.
In eukaryotic cells a molecular chaperone network associates with translating ribosomes, assisting the maturation of emerging nascent polypeptides. Hsp70 is perhaps the major eukaryotic ribosome-associated chaperone and the first reported to bind cotranslationally to nascent chains. However, little is known about the underlying principles and function of this interaction. Here, we use a sensitive and global approach to define the ... [more]

- High Throughput
Additional Notes
- isolation of cotranslationally bound SSB-RNC complexes allows us to identify the chaperone-bound nascent polypeptides through analysis of the mRNAs encoding the substrates
