This gene encodes a member of the prefoldin alpha subunit family.The encoded protein is one of six subunits of prefoldin, a molecular chaperone complex that binds and stabilizes newly synthesized polypeptides, thereby allowing them to fold correctly.The complex, consisting of two alpha and four beta subunits, forms a double beta barrel assembly with six protruding coiled-coils.The encoded protein may also repress the transcriptional activity of the proto-oncogene c-Myc.Alternatively spliced transcript variants encoding different isoforms have been described.[provided by RefSeq]
