Protein attributes

Sequence length	154 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Binds specifically to cytosolic chaperonin (c-CPN) and transfers target proteins to it. Binds to nascent polypeptide chain and promotes folding in an environment in which there are many competing pathways for nonnative proteins. Ref.7
Subunit structure	Heterohexamer of two PFD-alpha type and four PFD-beta type subunits. Binds to c-Myc; interacts with its N-terminal domain. Represses the transcriptional activity of c-Myc.
Tissue specificity	Highly expressed in pancreas and skeletal muscle and moderately in other tissues.
Sequence similarities	Belongs to the prefoldin subunit alpha family.
